“…In this model, waste mobility is allowed between nodes, and its effect on the solution was discussed under both centralized and decentralized decision models. In Ma et al (2018), the authors also used a network optimization method for waste processing issues. In their study, a case from Louisiana, United States, is used, and monetary constraints are considered through different players in the network.…”

“…In the objective, α ij is used as a classification variable that can be determined by the grassroots government level. Then the problem can be solved through a location-allocation algorithm scheme that was proposed by Cooper (1963) and extended by Wu et al (2015) and Ma et al (2018). Related pseudocodes are…”

China has been promoting garbage classification in its rural areas, yet it lacks financial appropriation and fiscal decentralization to support waste processing projects. Though the existing literature has suggested fiscal decentralization strategies between different local government levels, few of the studies ascertain garbage classification efficiency from a quantitative perspective. To bridge the gap, this study examines the optimal fiscal decentralization strategies for garbage classification. It uses an optimization model while considering decision makers’ requirements regarding the fund allocation amounts at different government levels and the classification ratios in villages as constraints and decisions, respectively. A three-stage heuristic algorithm is applied to determine optimal landfill locations and efficient classification ratios for the garbage processing system in rural China, with an analytical discussion on the propositions and properties of the model. Our analytical results suggest that 1) the theoretically optimal solution is conditionally achievable, 2) the applied algorithm can achieve the optimal solution faster when the relationship between governance costs and classification ratios reaches some mathematical conditions, and 3) there is always a potential for increasing the retained funds between different government levels or for reducing the total appropriation from the county government. The numerical experiment on a primary dataset from 12 towns and 143 villages in the Pingyuan county of Guangdong province, China, does not only affirm the qualitative results, but it also provides insights into the difficulties encountered during the implementation of the garbage classification policy in China’s rural areas.

“…The chicken litter is both a valuable resource and an unavoidable by-product that must be disposed of due to the deterioration of the ecological situation near the poultry farms. A common method of utilization of the chicken litter is considered to be use as a fertilizer in agriculture due to the high content of nitrogen, phosphorus, and potassium [3]. However, due to the lack of a sufficient amount of land for need of fertilizer, expensive transportation of waste to storage sites, and environmental pollution, it is necessary to investigate the possibility of alternative use of this.…”

The purpose of the research is study the influence of the torrefaction process on the fuel properties of the chicken litter. Experimental studies on lab-scale system at five temperature regimes of torrefaction (220, 240, 260, 280, and 300 °C) with a holding time determined using thermogravimetric analysis were conducted. The products of the torrefaction are solid residue, non-condensable gases, and tar. For the feedstock and torrefied material the elemental composition, the lower calorific value, hygroscopicity limit and bulk density are determined. For liquid fraction the analysis of the chemical composition is carried out. The properties of non-condensable gases as chemical composition and calorific value - are investigated. Mass yields of the solid residue and tar, and specific volume yield of the non-condensable gases are presented. The conclusion about the optimum temperature regime for torrefaction of chicken litter based on the results of experimental studies is made.
