Dry Reforming of Biogas Over Li–Ni–Al Catalysts: Influence of Li Incorporation Method

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT Hydrogen is a promising source of energy, given the current context of depletion of fossil fuels and increased emissions of greenhouse gases. The technological route for obtaining this fuel from the dry reforming of biogas has received considerable attention from researchers, as it converts the polluting gases CH4 and CO2 into synthesis gas ...

Food waste and pay‐as‐you‐throw systems

Journal of the Agricultural and Applied Economics Association, EarlyView.
Abstract This study assesses the effectiveness of pay‐as‐you‐throw (PAYT) schemes in managing household food waste by comparing volume‐based and weight‐based approaches. Using a utility maximization framework and survey data from Korean households (2019–2022), we find that weight‐based PAYT more effectively reduces food waste by creating stronger ...

Optimizing feather hydrolysate via machine learning for microbial recycling of waste concrete fines

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND The concrete industry faces significant challenges from CO2 emissions and the disposal of waste concrete fines (WCF). Microbially induced calcite precipitation (MICP) can bind WCF into bioconcrete, but the high cost of commercial culture media hinders its application.

Effect of ammonium concentration on methane oxidation and CO2 removal in an anaerobic biotrickling filter treating synthetic landfill gas and leachate

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Landfill gas (LFG) and leachate are commonly treated separately through energy‐intensive processes. This study evaluated the integration of both streams in an anaerobic biotrickling filter (BTF) to achieve simultaneous methane (CH4) and carbon dioxide (CO2) removal coupled with ammonium (NH4+) transformation, and how the microbial ...
