Biodigesters can produce valuable methane from a range of feedstocks. End-I AG was interested in estimating the emission reduction potential for projects in Romania and Ghana. Over time, these calculations were expanded with a range of feedstocks and scenarios to use the biogas to crowd out fossil fuels.
EnD-I AG is a German company working in the field of renewable energy. It plans, builds and operatses plants both domestically and internationally which generate renewable energy from on sustainable raw materials, biogenic waste and methane deposits from landfill sites and coal mines.
The tool which we delivered to EnD-I covered the following feedstocks:
- Energy crops: grain silage, grain, grass, maize silage, sugar beet, potato, sunflower, leafy vegetable
- By-products: rapeseed cake, mash (schlempe), glycerine, grain dust, pomace (trester)
- Manure: cow manure, cow dung, pig manure, poultry litter
- Waste/Sludge: animal carcasses, flotate, sludge, separated grease, waste cooking oil, slaughterhouse waste, food waste
Emission reduction estimates were made for the following scenarios:
- Energy crops: no feedstock production
- By-products: landfilled, applied on land, combusted without energy recovery, combusted with energy recovery, disposed in a anaerobic lagoon, composted, used as animal fodder, used as raw material
- Manure and Waste/sludge: landfilled, applied on land, combusted without energy recovery, combusted with energy recovery, disposed in a anaerobic lagoon, disposed in a aerobic lagoon, composted, used as animal fodder, used as raw material
Jelmer Hoogzaad developed the tool as the technical consultant to the project team at Climate Focus.
