Abstract Orange peel is a fruit-based biomass produced in huge quantities worldwide, requiring an appropriate management strategy to meet the waste-to-wealth approach. In current study, this agricultural waste was used (as adsorbent) treat dye-laden wastewater, followed by its regeneration and recyclability for dual biogas biochar production. An adsorbent material prepared mixing orange powder ...

From value-addition viewpoint, the aim of this study was to evaluate the stability of antioxidant capacity of pomegranate fruit co-products in different solvent extracts using the FRAP, DPPH ̇ and ABTS ̇+ assays during in vitro digestion. Antioxidant capacity in the investigated assays were in the order of peel > marc > juice throughout the in vitro digestion irrespective of the extraction solven...

This work investigated the potential of generating biogas from mono-digestion various substrates such as food and fruit waste (e.g., durian shell, dragon peel pineapple peel) co-digestion in different combinations a co-substrate well types (durian peel). The mixture ratio varied follows: 75:25, 50:50 25:75, which was based on weight. batch experiments were carried out using 125 ml anaerobic dig...

Human obesity is a global epidemic, which causes a rapidly increased frequency of diabetes and cardiovascular disease. One reason for obesity is the ready availability of refined food products with high caloric density, an evolutionarily new event, which makes over-consumption of food inevitable. Fat is a food product with high caloric density. The mechanism for regulation of fat intake has the...

Conventional petroleum-derived plastics are recalcitrant to biodegradation and can be problematic as they accumulate in the environment. In contrast, it may be possible to add novel, biodegradable bioplastics to anaerobic digesters at municipal water resource recovery facilities along with primary sludge to produce more biomethane. In this study, thermal and chemical bioplastic pretreatments we...

The feasibility of the anaerobic co-digestion of coffee solid waste and sewage sludge was assessed. Five different solid wastes with different chemical properties were studied in mesophilic batch assays, providing basic data on the methane production, reduction of total and volatile solids and hydrolysis rate constant. Most of the wastes had a methane yield of 0.24-0.28 m3 CH4(STP)/kg VS(initia...
