Pleurotus ostreatus (P. ostreatus) is considered a high-quality food, rich in proteins and bioactive compounds important for maintaining human health. Lately, commonly used substrate oyster mushroom cultivation—wheat straw, more often replaced by alternative cellulose substrates originated from the agricultural food industry. Utilization of wastes cultivation has its added value: sustainable wa...

Leather industry, one of the polluting industries because of generation of huge amount of liquid and solid wastes, also emits obnoxious smell because of degradation of proteinous material of skin and generation of gases such as NH3, H2S and CO2. Solid wastes are raw trimmings, fleshings, chrome shavings, buffing dusts and keratin wastes. Accumulation of these wastes lead to sludge problem and c...

The ability of Aspergillus niger strains to support citric acid production using solid-state fermentation agricultural processing coproducts was examined in this review. Citric has been shown have a number commercial applications the food and beverage industries. A. capable elevated are known contain genetic mutations that stimulate overproduction organic likely involving cycle reactions. previ...

Medical wastes include all infectious waste, hazardous (including low-level radioactive) wastes, and any other wastes that are generated from all types of health care institutions, including hospitals, clinics, doctor (including dental and veterinary) offices, and medical laboratories (42). 1 The main focus of concern has been on the portion of medical wastes that are defined as infectious, and...

A cellulosic component was extracted from low-value palm tree wastes, empty fruit bunches, and functionalized through grafting with acrylic acid in a previous study. The as-synthesized poly(acrylic acid)/cellulose graft copolymer was applied in the current study as an adsorbent for the removal of the cationic dye methylene blue and the heavy metal lead from industrial wastewater. Factors and pa...

Utilisation of palm oil mill wastes to make soil conditioner through anaerobic co-composting is feasible and has the potential to maintain the natural resources, and to reduce the impact on environmental quality in the future. Co-composting process uses pressed-shredded-grinded empty fruit bunch (EFB) with activated sludge (AS) from the pond system of a palm oil mill as a suitable option for or...
