The Influence of Biochar and Solid Digestate on Rose-Scented Geranium (Pelargonium graveolens L’Hér.) Productivity and Essential Oil Quality

Agronomy, 2019
In recent years, biochar has generated global interest in the areas of sustainable agriculture and climate adaptation. The main positive effects of biochar were observed to be the most remarkable when nutrient-rich feedstock was used as the initial ...

How AI and Digital Technologies Can Enhance Sustainable Livestock Manure Management: An Overview From Treatment to Distribution

Sustainable Development, Volume 34, Issue 6, Page 7966-7985, October 2026.
ABSTRACT Sustainable livestock manure management sits at the nexus of climate, nutrient circularity and water quality. This review explores how artificial intelligence (AI) and digital platforms are used across four management stages, that is, treatment, storage, valorisation and distribution, and figures out where integration fails to deliver ...

Improvement of anaerobic digestion of sludge

Water Science and Technology, 2004
Anaerobic digestion improvement can be accomplished by different methods. Besides optimization of the process conditions, pretreatment of input sludge and increase of process temperature is frequently used. The thermophilic process brings a higher solids reduction and biogas production, a high resistance to foaming, no problems with odour, better ...

Life cycle assessment of anaerobic digestion of pig manure coupled with different digestate treatment technologies

Environment International, 2020
The direct use of digestate on farmlands as soil amendment is becoming an uneconomic option for farmers. Moreover, there are serious environmental concerns about its oversupply in regions with intensive biogas plants.

New perspectives in anaerobic digestion

Water Science and Technology, 2001
The IWA specialised group on anaerobic digestion (AD) is one of the oldest working groups of the former IAWQ organisation. Despite the fact that anaerobic technology dates back more than 100 years, the technology is still under development, adapting novel treatment systems to the modern requirements. In fact, most advances were achieved during the last

From seaweed to safe digestate: integrating anaerobic digestion and genotoxicity assessment to evaluate digestate quality as an agricultural substrate

Frontiers in Sustainable Food Systems
Seaweed is a valuable feedstock for anaerobic digestion, yet integrated evaluation of methane production and digestate quality across multiple species remains limited in Morocco.

Anaerobic digestion of aliphatic polyesters

Water Science and Technology, 2016
Anaerobic processes for the treatment of plastic materials waste represent versatile and effective approach in environmental protection and solid waste management. In this work, anaerobic biodegradability of model aliphatic polyesters, poly(L-lactic acid) (PLA), and poly(ɛ-caprolactone) (PCL), in the form of powder and melt-pressed films with varying ...

Anaerobic Digestion and Gasification of Seaweed [PDF]

, 2018
The potential of algal biomass as a source of liquid and gaseous biofuels is a highly topical theme, with over 70 years of sometimes intensive research and considerable financial investment. A wide range of unit operations can be combined to produce algal biofuel, but as yet there is no successful commercial system producing such biofuel. This suggests

A Computer Program for Modeling the Conversion of Organic Waste to Energy

Energies, 2011
This paper presents a tool for the analysis of conversion of organic waste into energy. The tool is a program that uses waste characterization parameters and mass flow rates at each stage of the waste treatment process to predict the given products.
