Article Abstract
Solid waste workers are exposed to variety of injuries and diseases at work. To study health disorders among workers in the waste management field and to assess their knowledge attitude and practice (KAP) towards hazardous exposure and safety measures. A cross-sectional study was carried out on 275 waste workers and an equal number as a group of controls from workers' relatives or workers not involved in waste management. Workers completed a self-administered or interviewer-based questionnaire containing data about (i) knowledge, e.g., management of wastes, types of hazards associated with solid waste management, and safety measures; (ii) attitude, e.g., opinions about mode of transmission of infection and safety measures; and (iii) practice, e.g., available safety measures to prevent exposure to hazards. Health education sessions were carried out with pre- and post-assessment of KAP. Both groups were assessed regarding the health status through history, general, and local examination (respiratory system and skin) in addition to spirometric measurements and complete blood count. A total of 275 exposed solid waste workers and 275 controls were included. A significantly higher prevalence of symptoms regarding respiratory, gastrointestinal, renal, musculoskeletal, and dermatological systems were detected among the exposed group than the controls (P<0.05). Significantly lower levels of RBCs, Hb, HCT, and MCH were reported among the exposed group than the controls (P<0.05). Among the exposed group vs. controls, FEV1 reported 99.75±13.35 vs. 104.83±10.47 (P<0.001), FEV/FVC% reported 98.88±15.32 vs. 102.72±14.36 (P=0.003), FEF% reported 99.64±17.06 vs. 103.07±19.38 (P=0.029), and PEF% reported 58.73±16.31 vs. 62.12±12.91 (P=0.007). Unsatisfactory knowledge was reported among 64% of solid waste workers, 69.1% had negative attitude, and 73.8% had unsafe practice. KAP was significantly higher post than pre-health education (P<0.001). Respiratory, gastrointestinal, and skin infections were common among solid waste workers. Assessment of KAP towards management of wastes, transmission of infection, exposure to sharps, and safety measures showed poor levels that got improved after health education. To maintain good health among solid waste workers, direct supervision with periodic medical examination and focused continuous health education are required.

Despite the many benefits of greenhouses, it is challenging to meet their heating demand, as greenhouses belong to the most energy-intensive production systems in the agriculture sector. Industrial symbiosis can bring an effective solution by utilizing waste heat from other industries to meet the greenhouse heat demand. This study proposes an optimization framework by which optimum symbiotic relationships can be identified.

Sinomonas species typically reside in soils or the rhizosphere and can promote plant growth. Sinomonas enrichment in rhizospheric soils is positively correlated with increases in plant biomass. However, the growth promotion mechanisms regulated by Sinomonas remain unclear.

The carbon emissions of three typical processes （AAO, MSBR, and oxidation ditch） were systematically analyzed from the perspective of the whole wastewater treatment process based on the annual data of eleven urban small and medium-scale WWTPs in the year 2022, and the effects of different influent characteristics （TP, TN, BOD, COD, influent volume, and COD/TN） on the carbon emissions were studied by using the partial least squares structural equation modeling （PLS-SEM） method. The results showed that indirect carbon emissions dominated the total carbon emissions of small and medium-scale WWTPs （69.5%）, and carbon emissions from electricity consumption were the largest source （43.

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.

The construction of "zero-free cities" is an effective plan to achieve the carbon peak plan, reduce pollution and carbon emissions, and promote a circular economy. Based on the WARM model and Emission factor method, the total carbon emission reduction of solid waste sources and disposal in each field during the implementation of the zero-free city policy in Chongqing （2017-2021） was calculated, and the total carbon emission reduction of solid waste in each field in 2025 was predicted by scenario. The results showed that： ① After the implementation of cleaner production and green manufacturing policies in Chongqing, the generation intensity of general industrial solid waste decreased to 0.
