Vietnam's First Full-Cycle Waste Valorization Company

Waste Is A
Resource.

CBE converts mixed municipal and industrial solid waste into organic bio-fertilizer and energy pellets — using proprietary lab-engineered bacteria and anaerobic digestion. Zero chemicals. Zero landfill.

The Scale of the Problem

Vietnam's
Waste Crisis

65K
Tonnes per day of solid waste generated across Vietnam — growing 10–16% annually in cities.
75%
Of waste is landfilled or openly dumped — organic matter rots untreated, producing methane and leachate.
$2.9B
Annual value of recoverable materials discarded — organic compost, energy pellets, biogas all wasted.
<10%
Of waste treated by modern, resource-recovering facilities.

Vietnam's cities produce 7,000–9,000 tonnes of household waste per day in Hanoi and Ho Chi Minh City alone. Plastic accounts for 8–12% of that — 3.8 million tonnes of plastic waste annually, 75% of which is mismanaged.

The result is staggering: leachate contaminating groundwater, methane emissions accelerating climate change, and $2.9B in recoverable material value buried in the ground every year.

Policy is catching up fast. Stricter EPR obligations under Decree 05/2025, regional treatment targets under Decision 611, and Vietnam's national Net-Zero 2050 pledge are creating mandatory, growing demand for exactly what CBE does.

The Technology

From Bin
To Value

A fully integrated 4-stage process that handles mixed waste as-is — no pre-sorting required from citizens. CBE's proprietary lab-engineered bacteria accelerate decomposition that normally takes 6–12 weeks into just 24 hours at 150 t/day throughput.

Critical Application

Solving The #1 Problem
In Livestock &
Food Processing

Ammonia and hydrogen sulphide (H₂S) build-up in pig, poultry and processing environments is not just a smell issue — it is a direct animal welfare, food safety, worker health, and regulatory compliance crisis. CBE's bio-bacteria eliminates both gases at source within 24–48 hours, while simultaneously drying out floor and surface moisture — no chemicals, no ventilation overhaul required.

🐷

Pig Confinement Barns

Pig slurry produces H₂S and ammonia at dangerous concentrations. Wet bedding compounds infection risk and promotes foot rot. CBE bio-bacteria applied to barn floors and slurry pits neutralises H₂S within 24 hours, actively dries surface moisture, and suppresses ammonia re-release — reducing barn odour complaints by the surrounding community by over 80% in pilot sites.

H₂S neutralised in 24h Surface moisture reduced No chemical inputs
🐔

Poultry Barns & Broiler Houses

Ammonia from litter decomposition stunts bird growth, causes airsacculitis, and triggers early flock mortality. Wet litter creates coccidiosis and footpad lesions — a major animal welfare and export-quality issue. Bio-bacteria sprayed or mixed into litter actively competes with putrefactive bacteria, halting ammonia generation, binding moisture, and extending litter usability between cleanouts from 6 to 12+ weeks.

Ammonia suppression Litter life doubled Footpad lesions reduced
🏭

Pork & Poultry Processing Factories

Processing floors accumulate blood, fat, and organic matter that generate intense H₂S and putrefaction odours within hours. Wet surfaces are a primary vector for Salmonella and Listeria cross-contamination — a direct food safety and export-certification risk. CBE bio-bacteria applied as a floor wash or surface spray breaks down organic residues biologically, eliminates odour-producing bacteria, and keeps surfaces drier between deep cleans — meeting HACCP and export-grade hygiene standards.

Pathogen load reduced HACCP compatible Export-quality compliance
🐟

Seafood Processing Plants

Fish and shellfish processing generates trimethylamine (TMA) and H₂S — some of the most acute organic odours in any food industry. Export-quality compliance for markets in Japan, Korea, and the EU increasingly requires verified odour and surface hygiene standards. Bio-bacteria applied to processing surfaces, drain channels, and waste holding areas eliminates TMA and H₂S at source — without corrosive chemical washes that damage equipment and create wastewater treatment burdens.

TMA & H₂S eliminated EU / Japan export ready Equipment-safe
How It's Applied
