The influence range of the biogas desaturation method for mitigating sand liquefaction

Published in Frontiers in Earth Science

To clarify the influence range and saturation distribution after the biogas desaturation method is applied, a three-dimensional model is established with TOUGH2 software to analyze the effect of construction parameters such as grouting volume, grouting rate, grouting depth, nitrogen source concentration, and soil porosity. After that, the sensitivi...

Multicriteria analysis of sustainable agri-food waste management for an agroecosystem in Finland

Published in Frontiers in Sustainable Food Systems

Introduction The reliance on fossil inputs of agricultural practices has led to maximizing yields and profitability, even at the expense of environmental sustainability. Implementing circular waste management solutions could help align the economic and environmental goals of farmers while reducing their reliance on fossil inputs. The co-application...

Biohydrogen: prospects for industrial utilization and energy resiliency in rural communities

Published in Frontiers in Industrial Microbiology

Biohydrogen (bioH2) production in rural regions of the United States leveraged from existing biomass waste streams serves two extant needs: rural energy resiliency and decarbonization of heavy industry, including the production of ammonia and other H2-dependent nitrogenous products. We consider bioH2 production using two different strategies: (1) d...

A review of aquatic plant biomass pretreatment methods for biogas production

The increasing global demand for renewable energy sources has led to interest in generating biogas from aquatic plant biomass. This research examines the pretreatment methods of biomass, aiming to enhance the efficiency of biogas production processes. The analysis presents mechanical, chemical, biological, or combined pretreatment techniques, asses...

Advances in mixed-matrix membranes for biorefining of biogas from anaerobic digestion

Published in Frontiers in Chemistry

This article provides a comprehensive review of the state-of-the-art technology of polymeric mixed-matrix membranes for CO2/CH4 separation that can be applied in medium, small, and domestic biogas systems operating at low pressures (0.2–6 kPa). Critical data from the latest publications of CO2/CH4 separation membranes were analyzed, considering the...

Challenges for Biomass Production in the Context of an Expansion of Biogas Plants

Published in Proceedings of the International Conference on Business Excellence

The evolution of European states is based on access to information and knowledge, as well as innovative methods. Thus, the European states began to be more and more aware of the fact that protecting the environment and preventing the destruction of ecosystems are the key elements for progress. Current thinking is based on the continuous transformat...

Enhancing energy recovery from aquaculture residual materials: a focus on anaerobic digestion of African catfish (Claria...

Published in Frontiers in Sustainable Food Systems

In Germany, warm water Recirculating Aquaculture Systems (RAS) are generally integrated with biogas plants. The process sludge produced in aquaculture could be utilized to generate energy. This study investigates the potential of process sludge from commercial African catfish (Clarias gariepinus) warm water RAS, alongside associated plant productio...
