Compost Quality Assessment of Various Agricultural Wastes and Organic Manures

(Corresponding) Radwan S., (Corresponding) Ashour E.
Topic: 
Solid waste management
Today the quality of compost is the most essential criterion in recycling organic wastes, as well as its marketing and utilization in agriculture. Environmentally safe recycling of organic waste to agricultural land could be crucial to sustaining soil productivity in Mediterranean areas, where soil...Read more

High-rate anaerobic co-digestion of agro-industrial wastes combined with ammonia recovery and biogas purification

Eftaxias A., Georgiou D., (Corresponding) Diamantis V., Koumara A., Koskinari M., Aivasidis A.
Topic: 
Environmental biotechnology and bioenergy
Screened dairy manure, pressure-sterilized animal by-products, and cheese whey were co-digested in a Plug Flow Reactor (PFR) over a period of 150 days. The mixture was characterized by TCOD = 70±8 g/L, SCOD = 26±6 g/L, NH4-N = 1.5±0.3 g/L, TSS = 20±5 g/L, VSS = 18±6 g/L, TS = 33±5 g/L, VS = 26±2 g/...Read more

Anaerobic co-digestion of poultry manure and used cooking oil for enhanced biogas production

(Corresponding) Eftaxias A., Gkalimanis P., Koskinari M., Koumara A., Diamantis V., (Corresponding) Aivasidis A.
Topic: 
Biowaste
Aim of this study was to evaluate the anaerobic co-digestion of diluted poultry manure (DPM) and used cooking oil (UCO). Mixtures of DPM with different UCO dosages (1 to 6% v/v) were prepared using a high-shear emulsifier and digested in batch anaerobic reactors. Increasing the UCO dosage resulted...Read more

Valorization of poultry manure extract enriched with sodium acetate in mixotrophic cultivation of Auxenochlorella protothecoides

Langousi I., Markou G., (Corresponding) Arapoglou D.
Topic: 
Recycling of materials to new products
Poultry manure (PM) is byproduct of intensive agricultural production and can be used as a low-cost microalgae growth substrate due to its nutrient and protein-rich content. Microalgae are capable to grow rapidly and thrive in different substrates, thus serving as a valuable source of biomass. In...Read more
