The beverage manufacturing industry is standing at a historic turning point. Pressure from consumers, strict legal regulations, and supply chain transparency requirements are no longer just trends but have become mandatory requirements.

1. Circular economy: from “encouraged” to mandatory “rules of the game”

The circular economy is no longer a distant concept. Regulations such as the EU Packaging and Packaging Waste Regulation (PPWR) are creating immense pressure, requiring enterprises to take responsibility for the entire lifecycle of packaging – from design and use to recycling.

Challenges:

• Increasing the rate of recycled materials in packaging (PET bottles, aluminum cans, cartons).
• Designing products for easy sorting and recycling.
• Reducing energy, water, and raw resource consumption within the production process itself. Many factories are still struggling with this optimization problem.

2. ESG reporting and transparency: the “passport” for the global market

If your enterprise wants to reach the global market, especially the EU, Environmental, Social, and Governance (ESG) reporting is inevitable. New regulations like the EU Corporate Sustainability Reporting Directive (CSRD) compel enterprises (including those outside the EU) to publicly disclose data on emissions, resource usage, and social impact.

Challenges:

• Collecting and validating greenhouse gas emission data across the entire supply chain (Scope 1, 2, and 3).
• Building a clear and feasible emission reduction roadmap.
• Pressure to transparently disclose raw material origins.

3. Packaging restructuring: the shift from plastic to biological materials

The trend of shifting from traditional plastic bottles to friendlier packaging types such as fiber bottles or compostable packaging is becoming increasingly strong.

Challenges:

• Production costs for these new packaging types remain very high.
• Production scale has not yet met the demand of large corporations.
• Production technology and end-of-life treatment for these materials require synchronous investment and research.

4. Regenerative agriculture: ensuring sustainable raw materials from the roots

Input materials (barley, hops, fruits, sugarcane) determine product quality and are also a significant part of an enterprise’s carbon footprint. Large corporations like PepsiCo are pioneering investments in regenerative agriculture to improve soil health and reduce emissions.

Challenges:

• Initial investment costs and technical transition for farmers are substantial.
• It takes time to see distinct results in productivity and quality.
• Building a sustainable supply chain requires close cooperation and long-term commitment.

5. By-product treatment: turning “waste” into “golden resources”

Brewers’ grains, fruit pomace, rice husks… are massive by-products of the beverage industry. Instead of viewing them as waste needing treatment, many enterprises are researching to turn them into raw materials for new products, animal feed, or biofuels.

Challenges:

• By-product recycling and reuse technologies are not yet widespread and require large investments.
• By-product treatment processes often generate wastewater with very high organic pollution concentrations (high BOD, COD), putting heavy pressure on existing treatment systems.

The changes above are not burdens, but opportunities for pioneering beverage manufacturing enterprises to affirm their position, build sustainable brands, and conquer the most demanding markets. Proactively investing in a solid environmental infrastructure today is a strategic move for future development.

Do not let wastewater treatment, water supply, or exhaust gas issues become barriers. With leading experience and technology, we are ready to become a strategic partner, providing “tailor-made” solutions to help your enterprise not only meet regulations but also optimize costs and enhance brand image.

The pig farming industry in Vietnam is undergoing strong transformations, abandoning small-scale, fragmented farming methods for industrialized, large-scale centralized models. This change aims not only to meet the growing market demand but also to improve productivity, control disease, and optimize profits.

However, accompanying development is a massive environmental challenge. The more modern and centralized the farming models, the more urgent the waste treatment issue becomes. Let NGO analyze deeper into the trending models and find sustainable answers to the accompanying environmental problem.

I. Large-scale pig farming models in Vietnam

Two prominent industrial pig farming models suitable for development orientation in Vietnam include:

1. “Pig Apartment” Model (High-rise Farming) – The Future of Centralized Farming

This is the most breakthrough model, highly appreciated by the Ministry of Agriculture and Rural Development, and being proposed by pioneer large enterprises, promising to completely change the face of the livestock industry.

• Context and Implementation Momentum:
  This proposal stems from lessons learned from China. Facing pressure to ensure pork supply for 1.41 billion people after heavy losses from African Swine Fever, China strongly implemented the “pig apartment” model. Results were impressive: since 2018, over 2,000 models with nearly 4,500 high-rise buildings have gone into operation, demonstrating its efficiency and feasibility. In Vietnam, large enterprises like BAF (cooperating with Muyuan Group) and Xuan Thien Thanh Hoa have officially submitted projects, showing this is a trend with a solid practical basis.

• Superior advantages thanks to high-tech integration:
  According to the Ministry’s assessment, the power of this model lies in integrating a series of Industry 4.0 technologies:

  • Automation & Smart Farming: The entire process is automated, monitored by sensors, and Artificial Intelligence (AI) analyzes images and sounds of individual pigs in real-time. This helps in early disease warning, growth estimation, and sales process optimization.

  • Land and Labor Saving: Land use efficiency can increase up to 4.3 times compared to traditional farming. Simultaneously, one worker can manage up to 2,000 pigs, solving labor cost and management efficiency problems.

• Advanced Biosecurity and Environmental Control:
  The model is designed with a multi-layer biosecurity system. Specifically, the air environment is strictly controlled through a four-layer filtration system, capable of removing over 95% of odors and harmful bacteria. This is a key factor in remotely preventing dangerous diseases like ASF, PRRS…

• Environmental challenges at massive scale:
  Although integrated with smart waste treatment systems, the nature of this model is centralization at extremely high density. The entire volume of wastewater and manure from tens of thousands of pigs will concentrate at a single point. This places huge pressure on the treatment system. Any error or overload incident can lead to serious environmental consequences, requiring a final treatment technology that is extremely powerful, stable, and reliable.

2. Closed chain farming model (3F Model: Feed – Farm – Food)

This is a common industrial model proved effective by “giants” in the Vietnamese livestock industry.

• Nature & Advantages: Enterprises autonomously control the entire value chain: from the feed manufacturing plant (Feed), to the farm system (Farm), and finally the food processing plant (Food). This model helps absolutely control input-output quality, trace product origin, and build brands sustainably.
• “Hidden” Challenges:
  • The truth about Biogas digesters: Most 3F farms build Biogas digesters to treat waste. Biogas does a good job of reducing odors and converting part of organic matter into fuel gas. However, this is only a preliminary treatment step.
  • Post-Biogas wastewater remains heavily polluted: Wastewater leaving the Biogas digester still contains concentrations of Ammonium (NH4+), Nitrogen, Phosphorus many times higher than permissible limits. If this water source is not treated at a higher level, it will never meet QCVN 62-MT:2016/BTNMT and illegal discharge will cause serious pollution to surface water and groundwater.

II. Common bottlenecks and solutions from NGO experts

Whether high-rise “apartments” or closed 3F chains, both advanced models lead to a critical bottleneck: wastewater treatment. Traditional methods like Biogas are no longer sufficient to thoroughly solve this problem, especially as environmental regulations tighten.

Understanding that knot, NGO has brought a wastewater treatment solution applying modern microbial technology, designed specifically for industrial pig farming models.

NGO’s solution directly addresses existing problems:

• Thoroughly treating Ammonium, Nitrogen & Phosphorus – factors that Biogas digesters leave unresolved.

• Lean system, saving construction area, especially suitable for “apartment” models or farms wanting to reserve land for expansion.

• Can eliminate Biogas digesters, helping reduce initial investment costs and eliminating Methane (CH4) emissions causing the greenhouse effect.

• Commitment to output water meeting Standard A (QCVN 62-MT:2016/BTNMT), allowing enterprises to reuse water for watering plants, cleaning barns, aiming for a circular economy.

The application of a modern, effective wastewater treatment technology not only helps businesses comply with the law but is also a strategic investment step for sustainable development and building a “green brand” image.

Effective from July 1, 2025, regulations regarding the issuance of construction capability certificates for organizations were officially abolished. This groundbreaking change is expected to remove an administrative “barrier,” creating a healthier and more transparent competitive environment for businesses in the industry, including specific sectors such as the construction of wastewater treatment works.

This change came into effect based on the provisions of the Law on Railways 2025, issued by the National Assembly on June 27, 2025. Specifically, this law abolished Clause 4, Article 148 of the Law on Construction 2014 (amended and supplemented in 2020), which was the provision requiring organizations participating in construction activities to possess capability certificates.

From pre-inspection to post-inspection

• Previously, the capability certificate was considered a state management tool and often became a mandatory requirement in many bidding dossiers for state-funded projects. However, in reality, this regulation was sometimes abused, becoming a burden and an invisible barrier for many contractors.
• With the new regulation, the burden of administrative procedures for new issuance or re-issuance of certificates will be completely removed. Instead, organizations participating in construction activities will self-disclose information regarding their capabilities. The state management mechanism will shift from “pre-inspection” (checking certificates before participation) to “post-inspection”. Accordingly, the Departments of Construction will be responsible for inspecting and handling violations regarding compliance with capability conditions of organizations within their management jurisdiction.

No overlap with Decree 175/2024/ND-CP

Many may wonder if the abolition of certificates causes overlap or conflict with Decree 175/2024/ND-CP, which details the management of construction activities and mentions capability management.

However, it is necessary to clarify that:

• The Law on Railways 2025 abolishes the requirement for certificates – effectively removing an administrative procedure, a type of “sub-license”.
• Decree 175/2024/ND-CP details the capability conditions that an organization must meet (such as personnel, equipment, experience, finance) to implement a project.

Thus, abolishing the certificate does not mean abolishing capability requirements. Enterprises, including contractors in the wastewater treatment sector, must still ensure full compliance with capability conditions as prescribed. The key difference is that now they do not need to apply for a paper certificate but instead must self-declare and take responsibility for the honesty of the information they publish.

The essence of the contractor’s capability and experience will be demonstrated more comprehensively through similar contracts, personnel capacity, and specific equipment in the bid dossiers. This change is assessed to help construction businesses focus on their core competencies, which are project quality, progress, and innovation, rather than being bound by formalistic administrative procedures.

I. General characteristics of pharmaceutical & cosmetic wastewater

Unlike domestic or typical industrial wastewater, pharmaceutical industry wastewater contains complex compounds.

Active Pharmaceutical Ingredients (APIs)

Contains Active Pharmaceutical Ingredients (APIs), excipients, organic solvents (ethanol, methanol…).

Heavy metals

May contain heavy metals from the coating process or equipment.

High pH

pH fluctuates strongly due to the use of acids/bases in production.

Colorants, additives

May contain colorants and additives for pharmaceutical/chemical production lines.

High COD, BOD

High COD and BOD levels, difficult to biodegrade and existing in micro-particle form: Due to containing many organic compounds from drugs, solvents, additives…

Other components

Pollution components change continuously: Because the pharmaceutical industry constantly innovates drug formulas, making control and treatment more difficult.

II. Pharmaceutical wastewater treatment system diagram

Wastewater from production and cleaning processes is collected in the collection tank, then pumped through the screening device to remove coarse trash, avoiding system clogging. Next, wastewater flows through **serial contact oxidation tanks (1, 2, 3)** – here air blowers provide continuous oxygen for the oxidation process of organic substances (BOD, COD), TN, TP

Contact oxidation filtration technology uses contact materials with a 3D structure submerged in the treatment tank, supplemented with oxygen from air blowers to allow the oxidation reaction of pollution components to take place. Contact materials allow the oxidation efficiency to increase manifold and be distributed evenly throughout all areas of the treatment tank.

R&D results in the lab as well as actual operating data prove COD removal efficiency reaches 125mg/L – 250 mg/L per 1m3 of contact material.

After the reaction stage, pollution components are converted into waste sludge in the water, and separated from the water source at the phase separation tank. Settled sludge and floating sludge are collected in the sludge holding tank for periodic treatment or suctioning. The clear water is sent to the disinfection tank using Chlorine or UV rays to destroy harmful microorganisms before being discharged into the environment, ensuring compliance with discharge regulations.

III. How are Vietnamese Pharmaceutical factories treating wastewater?

Treating production wastewater physically/chemically keeps operating costs high; many factories cannot afford to maintain operation according to the design

For factories using biological technology, microorganisms often encounter load shock phenomena and unstable operation

Operating staff encounter many difficulties in handling incidents during operation, lacking the ability to standardize operating procedures.

IV. NGO’s solution is completely distinct in the market

With understanding of the properties of raw materials used in pharmaceutical and chemical production activities, NGO designs systems with different treatment levels, completely suitable for the specific characteristics of each factory

The system consists of 3 main oxidation reaction treatment steps

Level 1: BOD Oxidation

Level 2: Oxidation of preservatives, surfactants from line cleaning chemicals, and TN nutrients

Level 3: Oxidation of trace soluble COD difficult to biodegrade

NGO’s solution allows:

• Minimizing chemical consumption compared to advanced oxidation or activated carbon adsorption methods
• Stable system operation, good treatment of toxins harmful to microorganisms that cause load shock to the system
• The system personalizes additional treatment steps depending on the reuse purpose of each factory.

The dairy processing industry in Vietnam is growing strongly along with the increasing demand for dairy products. Parallel to the economic benefits, the milk production process also generates a significant amount of wastewater.

On average, for every liter of milk processed, 2–6 liters of wastewater can be generated. This wastewater contains high concentrations of organic substances (lactose, fat, milk proteins, etc.), making the biochemical oxygen demand (BOD) of raw milk ~250 times higher than that of typical domestic wastewater. If not treated properly, dairy wastewater will cause severe pollution to the receiving water body, especially organic and nutrient pollution.

An inefficient treatment system can expose a business to fines of up to billions of dong, the risk of operational suspension, and worse, a media crisis that could destroy a painstakingly built brand image. A single non-compliant discharge incident can become a negative media focal point, causing immeasurable damage.

Don’t let wastewater become a legal risk and a critical vulnerability in your production chain. At NGO International, with nearly 10 years of experience, we don’t just provide a treatment system; we deliver a comprehensive solution, turning environmental costs into a smart investment, protecting your reputation, and ensuring sustainable development for your business.

I. Dairy Production Process and Wastewater Characteristics

The production process for dairy products (pasteurized fresh milk, yogurt, butter, cheese, powdered milk, etc.) involves many different stages. During this process, multiple wastewater sources are generated, mainly from equipment cleaning and raw material losses. The main sources of discharge include:

In general, most of the pollution in dairy plant wastewater originates from milk and dairy products lost during the production process. Therefore, minimizing leaks and maximizing the recovery of residual milk will significantly contribute to reducing the pollution load on the treatment system.

II. Current Common Solutions and NGO’s Differentiating Technology

Comparison of dairy wastewater treatment solutions between NGO International and traditional technology:

III. Case Study

• Background: A dairy processing plant with a capacity of 1200 m³/day, TSS = 500 mg/L, COD = 1000 mg/L. The old treatment system was frequently overloaded, effluent was unstable, and chemical costs were high.
• Solution from NGO International: Instead of applying a traditional anaerobic biological treatment method, a system for COD treatment and upstream fat and protein separation was implemented.
• Impressive Results:
  • TSS reduced by 90% & COD reduced by 50% after just one treatment step.
  • Reduced pollution load on the biological system, helping it operate stably & eliminating shock load phenomena.

NGO, in partnership with Krofta—which holds over 20 patents and has experience in more than 40 countries worldwide—is committed to delivering quality solutions for dairy industry projects.

Traditional craft villages play a crucial role in Vietnam’s rural economy, creating jobs for millions of laborers and preserving cultural identity. However, spontaneous development with outdated technology has led to a serious environmental pollution problem, especially water pollution. Wastewater from craft villages often contains high levels of organic matter, toxic chemicals, pathogenic microorganisms, etc., which, if not treated, will have negative impacts on the ecosystem and public health.

According to the 2020 Report on Environmental Protection Work by the Ministry of Agriculture & Rural Development, there are currently 4,575 craft villages nationwide, of which 1,951 are officially recognized, including 1,062 new craft villages and 889 traditional ones. According to the 2020 Report on Environmental Protection Work by the Ministry of Agriculture & Rural Development, only 16.1% of craft villages have a centralized wastewater treatment system that meets environmental protection requirements; the rate of craft villages with industrial solid waste collection points is 20.9%.

1. Composition and properties of craft village wastewater

Wastewater generated from craft villages has a very diverse composition, depending on the type of production. In general, the main pollution parameters commonly encountered include biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), nutrients (nitrogen, phosphorus), oil and grease, microorganisms (Coliform, E. coli), and many other specific pollutants (dyes, heavy metals, chemical solvents, etc.).

Source: National State of the Environment Report for the period 2016 – 2020

Craft village wastewater contains a diverse range of pollutants at high concentrations, far exceeding the environment’s self-purification capacity. Each type of production has its own unique pollution “footprint,” requiring an appropriate treatment process to thoroughly remove specific pollutants.

2. Common craft village wastewater treatment processes today

Given the pollution situation described above, the construction of wastewater treatment systems in craft villages is urgent. However, according to the report from the Ministry of Agriculture & Rural Development, only about 16.1% of craft villages have centralized wastewater treatment systems that meet the requirements. The majority of wastewater is still discharged directly into the environment or undergoes rudimentary treatment merely for compliance purposes. Below are the common processes and stages of craft village wastewater treatment currently applied in Vietnam.

• Preliminary treatment (pre-treatment)
• Physico-chemical treatment (coagulation, precipitation, neutralization)
• Biological treatment (aerobic, anaerobic)
• Disinfection and finishing

3. Optimal craft village wastewater treatment solution from NGO International

Urban wastewater is one of the main causes of water pollution in Vietnam. With rapid urbanization, the volume of wastewater from domestic, commercial, and industrial activities is increasing, while the wastewater treatment system has not kept pace, leading to direct discharge into the environment.

According to the Ministry of Natural Resources and Environment, Vietnam generates approximately 10 million m³ of urban wastewater daily, but only 12-15% of it is treated to standard. The remainder causes severe pollution to river systems, canals, and groundwater sources.

Impacts of urban wastewater pollution:

• Environment: Pollution of water sources, degradation of aquatic ecosystems.
• Health: Increased risk of skin, digestive, and respiratory diseases.
• Economy: Increased healthcare costs, decreased value of real estate and water resources.

1. Characteristic Pollutants in Urban Wastewater

Urban wastewater is primarily generated from the domestic activities of residents, commerce, services, and partly from small-scale industrial production.

2. Common Urban Wastewater Treatment Technologies Today

• Aerobic – anaerobic biological treatment: Common, moderately priced, good BOD and COD removal efficiency.

• MBR Technology (Membrane Bioreactor): High efficiency, produces reusable effluent.

• SBR Technology (Sequencing Batch Reactor): Saves space, suitable for small residential areas.

• Tertiary treatment: Removes nutrients, microorganisms, improves water quality for reuse.

However, many current systems are not optimized in terms of cost, footprint, or ensuring long-term operational stability under conditions of rapid urbanization and highly variable wastewater sources.

3. Solutions from NGO – Optimizing Urban Wastewater Treatment

• Customized design, suitable for residential areas, buildings, and commercial centers.
• Optimized footprint, Automation – Saves manpower, Easy to operate
• Effluent meets QCVN 14:2025/BTNMT Grade A, suitable for discharge into receiving waters or for reuse.

Decree 05/2025/ND-CP, issued on January 6, 2025, amends and supplements a number of articles of Decree 08/2022/ND-CP to detail the implementation of the Law on Environmental Protection. Below are the main changes:

I. Decentralization of Authority for Environmental Appraisal and Permitting:

• Provincial People’s Committees are delegated the authority to appraise environmental impact assessment reports and issue environmental permits for certain projects previously under the authority of the Ministry of Natural Resources and Environment. This aims to increase local proactivity and responsibility in environmental protection.
• The Ministry of Natural Resources and Environment still maintains its overall state management role, responsible for guiding and inspecting the implementation of environmental regulations nationwide.
• The issuance of an environmental permit can be carried out concurrently with the appraisal process of the environmental impact assessment report. This helps to shorten administrative time and procedures.
• Projects belonging to different groups may have different permitting processes and timelines. Projects with a higher risk of causing pollution will undergo a stricter appraisal and permitting process.
• Provincial Departments of Natural Resources and Environment are assigned the responsibility of advising the Provincial People’s Committee on environmental permitting.

II. Amendments and Supplements to Articles Related to Environmental Permits:

• The Decree adjusts regulations on the dossier, sequence, and procedures for issuing, renewing, modifying, reissuing, and revoking environmental permits. These regulations are made more detailed to facilitate implementation by businesses and management agencies.
• Regulations on the trial operation of waste treatment facilities after an environmental permit has been issued are also adjusted. Facilities must ensure that their waste treatment facilities operate effectively before commencing official operation.
• Added regulations on the responsibilities of project owners/facilities after being granted an environmental permit. They must ensure compliance with the contents of the permit, including monitoring, waste treatment, and other environmental protection measures.
• The cases where projects and facilities must have an environmental permit are more clearly defined to prevent legal loopholes or omissions.
• The content of the environmental permit is more clearly specified, including requirements for monitoring, waste treatment, and other environmental protection measures.
• There are regulations on the public disclosure of information regarding environmental permits to enhance transparency and accountability of management agencies and businesses.
• The term of the environmental permit is also specified more clearly.

III. Replacement and Supplement of Appendices:

• The Decree replaces and supplements many appendices related to the list of types of production, business, and services at risk of causing environmental pollution and other environmental criteria. These appendices are updated to align with the current situation and new environmental protection requirements.

• • Appendix II is amended regarding the list of production, business, and service sectors at risk of causing environmental pollution.
  • Appendix III is amended regarding the list of Group I investment projects with a high risk of adverse environmental impact.
  • Appendix IV is amended regarding the list of Group II investment projects with a risk of adverse environmental impact.
  • Appendix V is amended regarding the list of investment projects with a low risk of adverse environmental impact.
  • Appendices VIa, VIb add templates for community consultation in environmental impact assessment.
  • Appendix VIII amends the template for the report proposing the issuance of an environmental permit.
  • Appendix X is amended for the template of the report proposing the reissuance of an environmental permit.
  • Appendix XI is amended for the template of the report proposing the modification of an environmental permit.
  • Appendix XIII is amended for the template of the written request for issuance, modification, or reissuance of an environmental permit.
  • Appendix XV is amended for the template of the report on the results of the trial operation of waste treatment facilities.
  • Appendix XVI is amended for the list of projects and facilities exempt from environmental registration.
  • Appendix XXII is amended for the list of products and packaging subject to recycling.
  • Appendix XXIII is replaced for the list of products, packaging, and the contribution rates for waste treatment support.
  • Appendices XXXIa and XXXIb are added before Appendix XXXI.

• The appendices are amended and supplemented to align with the current situation and new environmental protection requirements.

IV. Amendments to Some Articles of Related Decrees:

• Decree 05/2025/ND-CP also amends and supplements some articles of Decree 134/2016/ND-CP on export and import tariffs. These amendments relate to tax incentives for environmental protection activities.
• Decree 05/2025/ND-CP also amends and supplements some articles of Decree 31/2021/ND-CP guiding the Law on Investment. These amendments relate to the appraisal of investment projects with environmental implications.
• Regulations on tax, fee, and charge incentives are also adjusted to encourage environmental protection activities.
• Regulations related to waste management, wastewater, and scrap importation are also amended. These amendments aim to enhance management efficiency and minimize environmental pollution.
• There are some adjustments related to environmental restoration deposits to ensure that resource extraction projects are responsible for environmental restoration after their operations conclude.
• Regulations on environmental monitoring are also adjusted to ensure the accuracy and reliability of monitoring data.

Decree 05/2025/ND-CP takes effect from January 6, 2025. Relevant organizations and individuals need to update and comply with the new regulations to ensure their activities are in accordance with environmental protection laws.
