Oilseed rape straw (ORS) is a kind of biorefractory waste widely existing in the rural area of China, which is highly suitable to mix with kitchen waste (KW) and duck droppings (DD) in two-phase anaerobic digestion (AD). This research introduced the importance of KW and DD addition to improve the biogas production and biodegradation of ORS. A set of comparative experiments were conducted on two...

Biowaste has been defined as “Biodegradable waste from gardens and parks, food kitchen homes, restaurants, collective catering services retail establishments, comparable processing plants” (Directive (2008)/98/EC (EC—European Commission, 2008) [...]

Greenhouse gas (GHG) emissions related to composting of organic waste and the use of compost were assessed from a waste management perspective. The GHG accounting for composting includes use of electricity and fuels, emissions of methane and nitrous oxide from the composting process, and savings obtained by the use of the compost. The GHG account depends on waste type and composition (kitchen o...

As part of environmental management policies in Europe, separate collection of organic household waste and nonorganic household waste has become increasingly common. As waste is often stored indoors, this policy might increase microbial exposure in the home environment. In this study we evaluated the association between indoor storage of organic waste and levels of microbial agents in house dus...

Kitchen waste is an important component of domestic waste, and it both harmful rich in resources. Approximately 1.3 billion tons kitchen are produced every year worldwide. high moisture, readily decayed, has unpleasant smell. Environmental pollution can be caused if this treated improperly. Conventional treatments (e.g., landfilling, incineration pulverization discharge) cause environmental, ec...

In this work, bromelain is recovered from triturated pineapple stem and rind (usually kitchen waste) through the precipitation process with alcohol at low temperature. The temperature control is crucial to avoid the irreversible protein denaturation and consequently improving the precipitation yield. The process is carried out in a fed-batch system, so that its dynamic nature poses challenging ...
