Circular utilization of food waste to biochar enhances thermophilic co-digestion performance

چکیده

Codigestion is an emerging approach to improve wastewater sludge biogas production and valorize food waste (FW). This study explores FW-derived biochar as a codigestion amendment for the first time reports matrix experiment using four diverse amendments (mixed waste, pinewood, bonechar, unamended control) across FW types (vegetable, rice, chicken, mixed). It demonstrated that derived from mixed can greatly performance of yield relative control other biochars. The (MFW) led 34.5%, 35.6%, 47.5% increase in methane compared biochars made wood, bone non-amendment control, maximum rate MFW reactors could be up 6.7–9.9 times control. These results suggest more circular utilization by integrating with bring great benefits management.

A pilot-scale comparison of mesophilic and thermophilic digestion of source segregated domestic food waste.

Source segregated food waste was collected from domestic properties and its composition determined together with the average weight produced per household, which was 2.91 kg per week. The waste was fed over a trial period lasting 58 weeks to an identical pair of 1.5 m(3) anaerobic digesters, one at a mesophilic (36.5 degrees C) and the other at a thermophilic temperature (56 degrees C). The dig...

Effect of a Trace Element Addition Strategy on Volatile Fatty Acid Accumulation in Thermophilic Anaerobic Digestion of Food Waste. Waste

Purpose: A trace element supplementation strategy previously shown to be effective in mesophilic conditions was tested for thermophilic digestion of source segregated domestic food waste. Method: Inoculum from a mesophilic anaerobic digester treating municipal wastewater biosolids was successfully acclimated to thermophilic temperature (55 o C) with food waste as a substrate. Four laboratory-sc...

Co-digestion of source segregated domestic food waste to improve process stability.

Cattle slurry and card packaging were used to improve the operational stability of food waste digestion, with the aim of reducing digestate total ammoniacal nitrogen concentrations compared to food waste only. Use of cattle slurry could have major environmental benefits through reducing greenhouse gas emissions associated with current management practices; whilst card packaging is closely linke...
