ANAEROBIC DIGESTION & RESOURCE RECOVERY TECHNOLOGIES

We are a global technology leader for the production of clean energy, organic fertilizer and biochar from a broad range of organic waste streams. We offer state-of-the-art resource recovery technologies such as high solids anaerobic digestion for the municipal, industrial, commercial, and agricultural markets. Our resource recovery facilities stand for sustainability, local added value, and closed material cycles. Focusing on a clean and liveable environment through renewable energy (electricity, heat, biomethane) and fuel (CNG), as well as healthy soils through compost, organic fertilizer, and biochar. While creating new revenue sources for our clients, our technologies are also reducing greenhouse gas emissions.

“The sustainable use of resources is of great importance today. Biowaste and green waste from agriculture, the food industry, municipalities and waste disposal companies, in particular, are a raw material that is greatly underestimated. The correct utilization of these potentials leads to a profitable investment for operators, waste disposal companies and the environment”.

CASE STUDY: DIGESTION OF HORSE MANURE & STRAW

In Lehrte, Germany, the two farmers Adrian Bartels and Jens Boedecker use horse manure in our high solids anaerobic digestion system (biogas plant). How economically successful and ecologically sustainable this utilization can be is demonstrated by the farmers’ team with its new “problem solver”.

As a hobby and leisure partner, the horse has become an indispensable part of our society. A horse produces up to 50 kg of manure per day. With approx. 1.2 million horses in Germany alone, this is an enormous amount. Not only the animal itself, but also its dung, has become an economic factor. Especially when it comes to the energetic utilization of residual materials, the biogas plant is once again coming into focus. Biogas is produced by the fermentation of stackable manure from animal husbandry and other organic waste, which is converted into electricity and heat during the combustion process in a combined heat and power plant. Horse manure, which is mainly produced in rough quantities in larger operations and cannot be optimally utilized in conventional liquid digesters / biogas plants, causes disposal costs.

In addition to the energy production and usage of nutrient-rich valuable organic fertilizer, rebuilding the humus content in the soil became a great advantage compared to neighboring agricultural areas.

With approximately 1.2 million horses in Germany, slightly more than 10 times as much horse manure is produced each year. This enormous potential is currently not yet being used, see our latest Press Release
