Biogas purification and enrichment: sustainability metrics analysis of dry anaerobic digester with cashew apple bagasse substrate

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study hypothesizes that cashew apple bagasse‐based anaerobic digestion, combined with biochar purification, enhances biogas quality and sustainability. This study aims to investigate the performance and sustainability of a biochar‐based biogas purification technology using cashew apple bagasse as a substrate, with a focus on environmental

Testing the Impact of Waste from Anaerobic Digestion (Enriched with an Organic Component) on the Quality of Agricultural Land

GeoScience Engineering, 2017
Waste from anaerobic digestion is considered as a mineral fertilizer and it is usually applied to agricultural land. The aim of our attempt was to enrich this waste from anaerobic digestion (digestate) with an organic component (in our case represented ...

Circular economy assessment of biomethane value chain in Brazil

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract From the numerous opportunities to add value to biomass in Brazil, biomethane production in sugarcane mills presents significant potential. This study introduces a diagnostic framework grounded in circular economy (CE) principles to assess new biomethane projects, aligning with the strategic objectives of product diversification, full biomass ...

EFFECT of digestates derived from the fermentation of maize-legume intercropped culture and maize monoculture application on soil properties and plant biomass production

Chemical and Biological Technologies in Agriculture, 2022
Background The use of maize-legume mixed culture to produce renewable energy and fertilizers by anaerobic fermentation (AD), while respecting soil quality is a favourable approach in sustainable farming. This paper investigates how the substrate (silage)

Artificial Intelligence–Driven and Digital Practices for Circular Business and Finance: Insights for Advancing Hubs for Circularity

Business Strategy and the Environment, EarlyView.
ABSTRACT The emerging concept of Hubs for Circularity (H4Cs) presents an opportunity to create collaborative, self‐sustaining regional industrial ecosystems that drive circular economy transitions at scale. However, the operationalisation of H4Cs faces financial, organisational and data‐driven challenges.

Effects of Combined Application of Solid Pyrolysis Products and Digestate on Selected Soil Properties of Arenosol and Plant Growth and Composition in Laboratory Experiments

Agronomy, 2022
Biochars as soil amendments have been reported to improve soil properties and may have an important role in the mitigation of the consequences of climate change. As a novel approach, this study examines whether biochar and digestate co-application can be

Stripping‐based approach for the recovery of volatile fatty acids from anaerobic digestion digestate: preliminary experimental investigations and modelling

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Volatile fatty acids (VFAs) are widely used across industries: as intermediates in chemical production (e.g., solvents and polymers), in pharmaceuticals and cosmetics, and as preservatives and health‐promoting additives in food and animal feed. Emerging applications also include bioplastics, bioenergy, and biotechnology.
