Mar 23, 2023 · This paper also reviews modeling and simulation studies on poultry waste-to-wealth, and six current or emerging technological processes for poultry waste-to-wealth are described: anaerobic digestion, pyrolysis, gasification, hydrolysis, enzymatic treatment, and microbial conversion.
Jul 1, 2015 · Enzyme bioconversion is a feasible alternative to added-value to agroindustrial waste. • Poultry byproducts can be converted to feed and fertilizers. • Hydrolysates of poultry waste can be a source of bioactive peptides. • Production, purification and properties of microbial keratinases is discussed.
Jan 1, 2023 · The objective of this study was to optimize the process parameters of the anaerobic co-digestion of pig manure and rice straw to maximize methane production and system stability. In this study, batch experiments were conducted with different mixing ratios of pig manure and rice straw (1:0, 1:1, 1:5, 1:10, and 0:1), total solid concentrations (6%, 8%, 10%, 12%, and 14%), and inoculum accounts
Feb 1, 2024 · In recent decades, owing to rapid population growth, a large amount of solid waste has been generated, becoming a global concern. According to the World Bank, the generation of municipal solid waste is expected to reach 3.4 billion tons annually by 2050 (Nanda and Berruti, 2021), of which organic waste accounts for the major part, at approximately 46% (Yang et al., 2015).
Aug 1, 2022 · The poultry industry is a fast-growing industry fuelled by overwhelming customer demand. Of the different poultry meat options, chicken is arguably the most popular as it is the second most staple food item in Malaysia after rice. Consequently, due to the overwhelming demand for chicken meat, chicken manure is produced in abundance.
May 15, 2021 · As an alternative, ex situ fermentation systems (EFSs) have emerged that use perishable carriers such as maize straw and coconut shell powder with thermophilic functional bacteria to treat livestock and poultry waste (Guo et al., 2013). EFS is a low-polluting, low-emission, organic agricultural technology that uses continuous dynamic
Due to the high demand for food and meat for the world's growing population, the agricultural sector is expanding every year. Timely and effective treatment is of utmost importance to utilize organic matter in agricultural waste and avoid environmental pollution.
