MAXIMUM energy
Each substrate has its own characteristics — our systems are designed for them. Waste, farm manure or energy crops: WELTEC BIOPOWER designs biogas plants that are specifically tailored to your organic materials. Our substrate database comprises more than 400 different substrates, which we have already successfully industrialized. In this way, we guarantee optimal fermentation, stable operation and maximum energy yield.
Animal manure is the classic biogas raw material. Our systems reliably digest cattle manure, pig manure or chicken droppings and provide you with energy for the farm — while recovering low-odour, nutrient-rich fertiliser.
Organic waste from industry, catering and households is a valuable source of energy. Our plants recycle biowaste into biogas and high-quality digestate.
Industrial and municipal wastewater contains organic waste that can be used for energy purposes. With our biogas reactor, wastewater treatment becomes an energy gain.
Customers all over the world rely on our biogas plants. Find out how different industries generate sustainable energy using WELTEC technology.
Do you have any questions about your biogas project? Our team of experts will provide you with individual advice — from the very first idea through planning the implementation.
Energy crops such as corn, grass or grains offer high gas yields and predictable output. Our systems are designed for efficient use of renewable organic material and enable farmers to create additional value directly from the field.
