Enhancement of Fermentation Performance in the Anaerobic Co-Digestion of Chicken Manure and Corn Straw under Biogas Slurry Reflux via Air Stripping of the Digestate

open access: yesAgronomy
Ammonium inhibition is a key limiting factor for anaerobic digestion when using chicken manure as the main substrate, especially in a digestion system with biogas slurry reflux. Air stripping is usually used as a recycled biogas slurry treatment. In this

Valorization of paper sludge for bioethanol and biogas production

open access: yesBiofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 817-825, March/April 2026.
Abstract This study evaluated the physicochemical properties and bioenergy potential of three distinct paper sludges: virgin pulp sludge (VP‐PS), corrugated cardboard sludge (CR‐PS), and tissue and printing paper sludge (TPR‐PS). From the experimental runs, VP‐PS exhibited the highest ethanol yield (46.8 ± 3.7 g L−1, 87.4% conversion), which can be ...

Combined Effect of Cetane Improver, Aluminum Oxide Nanoparticles, and Waste Cooking Oil Biodiesel Blend on a Dual Fuel Combustion Engine Run With Biogas Originated From Food Waste

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1372-1386, March 2026.
Sugarcane juice is clarified and fermented with yeast to produce ethanol and CO₂. The broth is refined through distillation and molecular sieves, yielding fuel‐grade ethanol stored for transport. Bagasse, vinasse, and residues are recycled as valuable by‐products, enabling a sustainable bioethanol production pathway ABSTRACT This study investigates the

Energy balance of different organic biogas farming systems [PDF]

open access: yes, 2008
The ecological impact of biogas plants depends on their integration into a given farming system. Therefore only farm-specific and no general statements are possible. In this paper, two different concepts of biogas production for an organic cash crop farm

Biogas recirculation technology: Effect on biogas purification, slurry characteristics, microbial activity and energy consumption

open access: yesEnvironmental Technology & Innovation, 2020
Abstract In the present study, effect of biogas recirculation on slurry characterization, microbial activity and biogas purification were studied. Two digester units, one for control treatment and another equipped with a gas compression system for recirculation treatment, were designed and constructed.

Acidification of Biogas Residues Stimulates Manganese Uptake in Wheat

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 1, Page 49-58, February 2026.
ABSTRACT Background Efficient application of organic fertilizers contributes to resource‐efficient agriculture. Acidification of liquid manure effectively reduces ammonia (NH3) emissions. However, the effect of acidification on other plant nutrients, such as Mn, often a yield‐limiting nutrient in cereal production, is not well understood.
