Methane Generation Using an Anaerobic Biodigester From Waste Leachate Water
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Leachate wastewater (LWW) is characterized by slow biodegradation and low biogas production due to resistant materials and limited biological activity. Therefore, applying pretreatments is essential to improving biodegradation potential, which consequently boosts energy recovery.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension

Liquid Paraffin as a Digestibility Marker in Young Calves
Journal of Dairy Science, 1973 Abstract Liquid paraffin was studied as a digestibility marker in calves receiving milk replacer, concentrates, and concentrates and roughage. Recovery of paraffin in the feces was high and stable. Fecal paraffin was highly correlated with fecal fatty acids, total nitrogen, dry matter, and ash.

PLANTS, PEOPLE, PLANET, EarlyView.Reusing organic waste materials, such as animal manure, as soil amendments reduces water and fertiliser demand, contributing to achieving the Sustainable Development Goals. However, organic wastes may contain contaminants of emerging concern (CECs), posing potential ecosystem and human health risks. Despite the importance of this issue, there is a lack

Short-Term Nitrogen Uptake of Barley from Differently Processed Biogas Digestate in Pot Experiments
Energies, 2019 The use of biogas digestate as fertilizer is limited by the farm nutrient balance. Mechanical separation and drying of digestate increases its transport worthiness as well as the economic feasibility of nutrient export. This study compares the fertilizer
