The biodegradation and hydrolysis rates of an aliphatic aromatic copolyester were measured in manure, food, and yard compost environments and in phosphate buffer solution (pH 1⁄4 8.0) and vermiculite at 58 C. Mineralization, molecular weight reduction, and structural changes determined by DSC, FTIR, and 1H NMR were used as indicators of the biodegradation and hydrolysis rates. Poly(butylene adi...

In this study, the suitability of biowaste and green waste composts in organic farming is presented based on quality assurance data approximately 21,000 compost analyses from 2015 to 2020. The evaluation was both legal regulations EU 2021/1165 requirements two largest German associations Bioland Naturland. 2020, 70.1% agreed with above-mentioned regulations, 21.6% exceeded limits for heavy meta...

In this study, twelve fungal lipase producing strains belonging to Aspergillus, Penicillium, Trichoderma and Mucor genera were isolated from palm oil mill effluent composts. The Aspergillus spp. were more frequent (42%) and was present in all the samples assayed. Mucor sp. was the least encountered (8.3%).The lipase producing profile showed that Trichoderma (8.07-8.24 u/mL) and Aspergillus (6.2...

suddenly come to the fore as another important environmental issue threatening California’s landscape and greenwaste recycling industries. Starting in 2001, articles began appearing in some of the state’s major newspapers which focused the public’s attention on the issue and raised its level of importance. It is borne out of problems that began in Washington state where herbicidecontaminated co...
