The landfill garbage includes organic and inorganic matter. The organic matter covers more than 50% of the total waste material. Due to improper management of landfill garbage, it causes serious risks to human health directly by the emission of toxic gasses. On the other hand, landfill sites are the natural habitat of several microbes and arthropods. The present discussion illustrates the impact of landfill garbage on insect ecology and human health. Here, we highlighted the arthropod density as well as diversity. Moreover, the population of insect vectors of various diseases, insect scavengers as well as pollinators has been pinpointed. It shows that landfill sites and adjacent areas are hotspots for a wide variety of arthropods. The proper management of landfill sites could reduce the population dynamics of various insect pests, and health risks could be decreased in low-and middle-income countries.

Domestic waste treatment is an important source of anthropogenic greenhouse gas emissions, and it is of great significance to clarify the carbon emission intensity of each link before and after waste classification treatment to help with the "double carbon" goal. Based on the relevant data on domestic waste generation in Baoji City in 2021, combined with the integrated urban and rural domestic waste disposal model, the carbon emission intensity of urban and rural domestic waste treatment before and after classification was calculated using the IPCC inventory guide carbon emission factor method. The results showed that by reducing the proportion of simple landfills in rural areas, the carbon reduction could reach 59 451.

In this study, a combined system of anaerobic-oxic-anoxic-oxic, coagulation and adsorption (AOAOCA) was used to treat the real waste transfer station (WTS) wastewater. The effects of hydraulic retention time (HRT), sludge reflux ratio (SRR), mixed liquid reflux ratio (MLRR), coagulant and zeolite on the contaminants removal efficiency were investigated. When the AOAOCA system was operated at the optimal conditions (HRT of 8 d, SRR of 70%, MLRR of 200%, PAFC as coagulant with dosage of 750 ppm and 1-3 mm zeolite with filling rate of 60%), the effluent COD, NH-N and TP could reach 82.

Although microplastic pollution is a global concern, information on the distribution of microplastics in petroleum and petrochemical urban soils is limited. In this study, we investigated the occurrence, ecological risk, and human exposure risk of microplastics in different land-use types of soil in Daqing Administrative region, a prominent petroleum and petrochemical industrial base in China. Stereoscopic microscopy and Fourier transform infrared spectroscopy (μ-FTIR) were used to study the chemical composition and distribution characteristics of microplastics.

The life cycle assessment methodology is a comprehensive environmental impact evaluation approach rooted in the "cradle-to-grave" concept. This study takes a municipal solid waste incineration power plant in central China as an example to comprehensively explore the potential ecological and environmental impacts of municipal solid waste incineration power generation through life cycle assessment methods. Burning one ton of waste can recover 7342 joules of thermal energy.
