‍Precise design for maximum
gas yield

WELTEC plants are designed for a wide range of organic waste materials: from municipal organic waste, food waste and food waste to industrial waste such as spent grain, slurry or glycerin to agricultural substrates such as manure, manure and energy crops. Each system is individually tailored to the available substrates and their properties.

Economic efficiency depends on several factors: substrate availability, plant size, gas utilization (electricity, heat, biomethane) and regional conditions. WELTEC prepares a detailed profitability calculation for each project and supports you with funding applications. Many investments pay for themselves within a few years.

It usually takes 12 to 24 months from planning to commissioning — depending on project size, approval process and individual requirements. WELTEC takes care of the entire project management: from approval to construction to training of your operating personnel.

The fermentation residues are rich in nutrients and are ideal as organic fertiliser in agriculture. They contain valuable nutrients such as nitrogen, phosphorus and potassium and can replace chemical fertilizers. This is how the cycle is closed sustainably.

Yes, WELTEC will also support you over the long term: We offer comprehensive service contracts, technical support, spare parts supply and remote monitoring of your system. Our goal is trouble-free, economical continuous operation — worldwide.

Absolutely. WELTEC analyses existing plants and develops concepts for increasing performance, expanding substrates or optimising gas utilization. Modernization of outdated technology is also part of our range of services.
