Biofuels, Bioproducts and Biorefining, EarlyView.Abstract The world's population is expected to grow rapidly, with the vast majority of people living in urban areas. Closing nutrient loops is therefore increasingly important for food security and environmental stability. In Germany however, the current treatment of organic and green waste and sewage sludge (derived from wastewater) includes ...

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Biogas purification technologies facilitate the production of value‐added products such as biomethane and industrial chemicals. This review was based on the assumption that biogas purification is underrepresented in the literature despite its significant potential for clean energy and greenhouse gas mitigation, warranting a comprehensive ...

Development of the Biogas Tractor with Two Biogas Feeding Algorithms [PDF]
IFAC Proceedings Volumes, 2008 The research on biogas tractor was started as a possible solution to reduce tractor's fuel consumption and increase farmer's benefit out of a biogas plant. The tractor was equipped with a fontal gas unit containing 4 cylinders of purified biogas (more than 95% methane) with a volume of 26.5 L each at 19.6 MPa.

Hazard Classification of Biogas and Risks of Large Scale Biogas Production
Chemical Engineering Transactions, 2013 This paper focuses on the approach that the Netherlands has chosen for large biogas-producing co- fermentors that fall under the Seveso Directive and for which a Quantitative Risk Assessment (QRA) needs to be performed. In this context, two main questions arise: 1) when does an establishment with a large amount of biogas formally fall under the Seveso ...

Hydrogenation of acid oils with in situ hydrogen generation for biofuel production
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract A sustainable hydrogen source is essential for improving the environmental performance of industries that are heavily reliant on hydrogen. Transitioning from commercial hydrogen to cleaner sources is vital for reducing fossil fuel dependence.
