Biogas

TL;DR: In this article, the authors evaluated vinasse anaerobic digestion in a sugarcane biorefinery in terms of energy, environmental, and economic considerations, and found that the energy potential of a single biorefa-finery is comparable to the electricity supply demand of a city of approximately 130,000 inhabitants or to the surplus energy from bagasse burning that is exported by some sugar cane mills in Brazil.

TL;DR: In this paper, the authors summarize the recent advances in biogas dry reforming toward hydrogen production, including the preparation of catalysts, the optimization of operation conditions, and the influence of impurities in Biogas.

TL;DR: In order to investigate the effect of feedstock ratios in biogas production, anaerobic co-digestions of rice straw with kitchen waste and pig manure were carried out and the optimal ratio of kitchen waste, pig manure, and rice straw was 0.4:1.

TL;DR: In this article, a 3x3 experimental design with duplicates was adopted (3 crop residuesx3 carbon/nitrogen ratios) to examine the improvement of batch digestion in terms of biogas volume produced.

TL;DR: In this paper, an economic and life cycle assessment of methane production via the combination of anaerobic digestion and power-togas (PtG) technology have been applied to sewage sludge valorization, and sensitivity analyses have been done on biogas upgrading technologies, electricity prices, annual operation time and composition of the electricity mix with also a comparison between PtG and direct injection.
