Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension

Short- and long-term impacts of anaerobic digestate spreading on earthworms in cropped soils

, 2021
International audienceAnaerobic digestion is increasingly used in Europe to treat organic substrates and produce biogas as a renewable energy source. The residual matter (digestate) is used in agriculture as an organic fertilizer.

Environmental impact assessment of biochar in anaerobic digestate [PDF]

, 2022
Climate change and unsustainable crop production are among the most prominent environmental issues and viable solutions must be looked for. A circular economy approach by recycling biochar-digestate back to agriculture as a fertilizer can be one of the ...

After-Effect of Biogas Digestate Used for Growing Seedlings on the Antioxidant System of Tomato (Solanum lycopersicum) Fruits

Applied Sciences
Digestate is primarily a by-product of anaerobic digestion, where organic waste is converted into biogas. Also, digestate has become an excellent tool for enriching the eroding and disappearing fertile soil and restoring its fertility over the past two ...

Biochar‐based fertilizers improve nutrient use efficiency in sunflower grown on a subtropical tidal soil

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Improving fertilizer use efficiency is essential for reducing environmental pollution, sustaining agricultural production, and maximizing the economic profitability of crop production systems. This study tested the hypothesis that the formulation strategy of biochar‐based fertilizers, rather than nutrient addition alone, is associated with ...

Immobilisation of anaerobic digestate supplied nitrogen into soil microbial biomass is dependent on lability of high organic carbon materials additives

Frontiers in Sustainable Food Systems
Anaerobic digestate is a nutrient rich slurry by-product derived from biogas production, often used as a fertiliser due to its high nitrogen content. However, nitrogen losses from its application can lead to environmental pollution.

A system dynamics‐based framework for bioenergy planning in sub‐Saharan Africa: integrating circular bioeconomy and Fourth Industrial Revolution technologies

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Energy scarcity remains a persistent challenge in sub‐Saharan Africa (SSA), where limited access to reliable, affordable, and clean energy constrains socioeconomic development. Biomass resources, including agricultural residues, forest waste, and waste from other biological sources, are widely available, but their use for modern energy ...

Enhancing nutrient recovery from food waste anaerobic digestate

, 2023
The study synthesised the raw liquid fraction of digestate into a nutrient rich solid digestate through acidification whilst preventing nitrogen loss through ammonium volatilisation during evaporation.

Recovery of nutrients from biogas digestate with biochar and clinoptilolite [PDF]

, 2016
The liquid fraction of digestate contains nutrients which makes it a valuable fertiliser in agricultural crop production systems. However, direct application of digestate may raise practical and environmental problems. Therefore, processes to concentrate

Biogas production from Opuntia stricta Haw.: microbial diversity and solid load influence on sludge recycle systems

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The search for alternative and sustainable energy sources becomes urgent as energy demand increases and fossil fuels become less available, especially in water‐scarce regions such as the Brazilian semi‐arid region, where current projections of global warming and the expansion of arid and semi‐arid zones point to a future of desertification ...
