Bioconversion of Agricultural Wastes into a Value-Added Product: Straw of Norwegian Grains Composted with Dairy Manure Food Waste Digestate in Mushroom Cultivation
نویسندگان
چکیده
Commercial mushroom production is based on composted locally available agro-industrial wastes rich in carbon and nitrogen such as wheat straw supplemented with chicken manure. Either component can be replaced by other kinds of grain straw: barley, oat, or a mixture different types combined diary manure—food waste digestate after anaerobic biogas digestion. Original, unseparated liquid nutritious, organic matter. This research aimed to investigate the effect ratios composting process productivity their consequent cultivation parameters Agaricus subrufescens. All investigated experimental compost (EMC) worked well during process, reaching desired moisture 65–75%, N content 1.43–1.93%, C/N ratio ranging from 21.5 29.1, supporting growth mycelium producing mushrooms. Supplementation barley resulted better EMC structure highest yield biological efficiency (BE) (157.9 g kg−1; 64%), whereas oat addition gave lowest BE (88.6 kg−1 38%). Precociousness (yield at mid-cycle crop development) was higher for substrates (68.9%), while earliness (days harvest casing) lower EMC.

The aim of this study was to investigate the feasibility of using nonmetallic printed circuit board (PCB) waste as filler in recycled HDPE (rHDPE) in production of rHDPE/PCB composites. Maleic anhydride modified linear low-density polyethylene (MAPE) was used as compatibilizer. In particular, the effects of nonmetallic PCB and MAPE on mechanical properties of the composites were assessed throug...
متن کاملAnaerobic digestion of municipal solid waste and agricultural waste and the effect of co-digestion with dairy cow manure.
Anaerobic digestion of dairy cow manure (CM), the organic fraction of municipal solid waste (OFMSW), and cotton gin waste (CGW) was investigated with a two-phase pilot-scale anaerobic digestion (AD) system. The OFMSW and CM were digested as single wastes and as combined wastes. The single waste digestion of CM resulted in 62m3 methane/ton of CM on dry weight basis. The single waste digestion of...
متن کاملAnaerobic Co-digestion of Dairy Manure with Potato Waste
In this study, anaerobic co-digestion of dairy manure (DM) and potato waste (PW) was evaluated to determine the best mixing ratio in terms of biogas and methane (CH4) productions. Batch lab-scale anaerobic co-digestion of DM with PW was conducted at two different temperature ranges [mesophilic (MT) (35-37 oC) and thermophilic (TT) (55-57 oC)]. The tests were conducted at five DM:PW mixing ratio...
