Determination of Methane and Carbon Dioxide Formation Rate Constants for Semi-Continuously Fed Anaerobic Digesters

Energies, 2015
To optimize commercial-scale biogas production, it is important to evaluate the performance of each microbial step in the anaerobic process. Hydrolysis and methanogenesis are usually the rate-limiting steps during digestion of organic waste and by ...

Sustainable Manufacturing Platforms for Closed‐Cycle Bioeconomy Applications

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The transition to a circular bioeconomy requires innovative production platforms that prioritize sustainability, resource efficiency, and waste minimization. Organic waste from agriculture, aquaculture, and food production represents an underutilized feedstock for biomanufacturing, contributing to a circular economy.

Dual valorization of bamboo waste via superheated steam torrefaction: Efficient bioenergy production and pollutant adsorption

Cleaner Engineering and Technology
Bamboo waste is an abundant renewable biomass, yet its direct use as fuel is limited by high moisture and low calorific value. Developing efficient valorization strategies is therefore essential for sustainable energy and environmental applications. This

Additives Enhancing Biodegradability in Plastics and Potential Implications for Textiles: A Mechanistic Review

Journal of Applied Polymer Science, EarlyView.
Mechanistic insights from additive‐assisted plastic degradation guide the design of environmentally adaptive textile fibers. Functional additives enhance oxidative, hydrolytic, enzymatic, and microbial degradation pathways. Translating these strategies requires control of fiber architecture, additive distribution, and environmental interactions ...

Hydrogen Permeability of Tubular Polymer Membranes for Biological Methanation Membrane Reactors

Journal of Applied Polymer Science, EarlyView.
A reproducible method for permeability measurements of tubular polymer membranes is developed and combined with a comprehensive review of hydrogen permeability data. Based on this analysis, a suitable tubular polymer membrane is identified for application in biological methanation within membrane reactors.
