Abstract The future European “Green Deal” will set ambitious greenhouse gas emissions
reduction by 2030. Reaching these targets will partly rely on the decarbonization of the gas …

Carbon-rich waste materials (solid, liquid, or gaseous) are largely considered to be a burden
on society due to the large capital and energy costs for their treatment and disposal …

Municipal solid waste (MSW) management has emerged as probably the most pressing
issue many governments nowadays are facing. Traditionally, Waste-to-Energy (WtE) is …

Biochar has been reported as an effective additive to improve methane production during
anaerobic digestion (AD). However, the mechanism for such a stimulatory impact remains …

Power-to-Methane as one part of Power-to-Gas has been recognized globally as one of the
key elements for the transition towards a sustainable energy system. While plants that …

Graphite and pyrolytic biochar are two electrically active but functionally distinct carbon
materials that have been widely used to enhance methanogenic performance of anaerobic …

To prevent an environmental collapse while feeding a future human population of 10 billion
people, dilute nitrogen in waste streams as a nitrogen source and carbon dioxide as a …

The objective of this study was to evaluate the effect of biofilm and external voltage on the
performance and microbial community composition of batch-fed, combined anaerobic …

A promising route to transition wastewater treatment facilities (WWTFs) from energy-
consuming to net energy-positive is to retrofit existing facilities with process modifications …

Anaerobic digestion (AD) is a widely used technique to treat organic waste and produce
biogas. This article presents a practical approach to increase biogas yield of an AD system …
