PRODUCTION WASTE
REUSE AND RECYCLE
BIOGAS FROM INDUSTRIAL WASTE
Industrial production processes generate large quantities of organic waste—ranging from food waste to brewery spent grain and distillers’ grains. These waste materials are valuable energy sources that serve as the basis for biogas production through anaerobic digestion. WELTEC BIOPOWER develops biogas plants for industrial companies that want to utilize their production waste on-site to generate energy, thereby lowering disposal costs, reducing energy expenses, and improving their carbon footprint. From vegetable processors and breweries to fats from the cosmetics industry—our plants are designed for maximum efficiency and reliability.

Individual investments
FROM THE FOOD INDUSTRY
TO THE CHEMICAL SECTOR
Industrial waste materials vary greatly in composition, consistency and energy content. WELTEC BIOPOWER develops individual fermentation concepts for every company, which are precisely tailored to the available substrates — from high-calorie fats to fiber-rich grains and liquid process water. Our systems are designed to be flexible and can also process highly fluctuating substrate flows. Intelligent process management maximizes gas yield and continuously optimizes operation. In this way, you reduce disposal costs and generate electricity and heat directly on site at the same time.

FOR INDUSTRIAL WASTE
WELTEC BIOPOWER technology is specifically designed for industrial waste: challenging compositions, fluctuating availability, or high contamination levels are no problem for us. Solutions for substrate preparation, digestate treatment, and biogas processing are tailored to your specific industrial requirements. All components are designed with one goal in mind: maximum gas yield, minimal disposal costs, and the cost-effective operation of your plant directly at the production site.
Double the Benefits
Reducing Costs, Generating Energy
Industrial biogas plants transform production waste into economic and environmental value. Instead of paying high disposal costs, companies generate renewable energy from their waste materials—in the form of electricity, heat, or biomethane. The energy produced on-site can be used directly in production, reducing dependence on external energy suppliers and lowering costs in the long term.
At the same time, companies significantly improve their carbon footprint: controlled digestion prevents methane emissions that would otherwise result from conventional disposal or open storage.
The digestate can often be marketed as fertilizer or further utilized. Many companies also benefit from incentive programs and can generate additional revenue by feeding electricity or biomethane into the grid.
WELTEC BIOPOWER designs every plant precisely to meet operational requirements: from substrate intake and digester design to gas utilization. Our plants are robust, reliable, and designed for maximum availability. We conduct feasibility studies, assist with permitting, and support you through to commissioning. This ensures your biogas plant becomes a key factor for economic and sustainable success.
