The problem of food waste, its unsustainable management, and associated environmental consequences are becoming great concerns due to the rapid socioeconomic development in many Chinese provinces. This study assessed the current and future status of food waste and its management, and the associated environmental impact in all Chinese provinces from life cycle perspective. Based on result, food waste in China was estimated as 61.37 Mt in 2020 and could be as high as 100.95–139.82 Mt by 2040, under various socioeconomic pathways. Average per capita food waste has increased by 29.67% from 2016 and Tianjin was found to have the highest per capita food waste. Correspondingly, GHG emission of food waste in China was estimated as 149.25 Mt CO₂eq in 2020, and is largely influence by the varieties of food wasted in each province. The environmental burden of food waste is projected to increase by 70%–148% under different socioeconomic development pathways.

Each day the facility mainly processed printers and peripheral devices, laser cartridges, and refurbishable flatscreen displays. The main material outputs were glass, mixed plastics, and computer and communication wires containing copper. The most valuable products were refurbished goods and the highest revenue material was copper, whereas the highest cost item was glass from cathode ray tube (CRT) displays, due to its lead content. From 2016–2018 the facility received fewer CRT displays due to both global e-waste trends, by selling and trading CRTs to other Ontario pre-processors in exchange for flatscreen displays. This approach helped the facility to capitalize new specialized equipment for the processing of flat screens and reduced downstream leaded glass processing costs.

ICT-based mobility services like ridesourcing provide smart tools and algorithms for matching travel demand and supply and more convenient door to door services. However, there is a concern that the convenience and competitive service fares of these new mobility modes encourage people to make more car travel or shift from more sustainable mobility modes like public transport to car travels. Therefore, it is necessary to study the frequency use and modal shift to this new mobility mode, particularly in the cities (like Cairo), where the ICT-based mobility services contain more ridesourcing of fossil fuel cars than other modes like online bikes/scooter sharing. A survey was conducted in Cairo, and logit models were developed to analyze the associations of socioeconomic, travel behavior variables with the frequency use and modal shift to ridesourcing. The results of ordinal logistic regression indicate that people who live near a metro station, with higher income, and with more non-work trips per week are more likely to be high-frequent users of ridesourcing. Moreover, women are more likely to use ridesourcing frequently than men in Cairo. The findings indicate that the most replaced mode by ridesourcing is traditional taxis (by 33 %), and the second and third shifted modes are private cars and public transport by 30% and 24 %, respectively. The results of multinomial logistic regression show that the socioeconomic parameters have significant associations with the probability of modal shift from public transport, taxis, and private cars to ridesourcing services.</p></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666916122000275/pdfft?md5=87a3ebbbd1b7df9e78daaf215dcbd6ae&pid=1-s2.0-S2666916122000275-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47345740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Alternative water resources, such as treated wastewater (TWW), offer a potential solution, while additionally contributing to a circular economy. To assess environmental sustainability, the impact of residual wastewater contaminants on soil microorganisms must be understood. This study compared soil microbial communities from purpose-grown tree groves irrigated with TWW for at least ten years, with communities from unirrigated control plots. Short-term batch testing was conducted to compare the degradation capabilities for five trace-level organic contaminants (TOrCs) associated with reclaimed wastewater. Microbial community composition was examined using 16S rRNA Illumina sequencing. Microbial biomass and abundance of a putative bisphenol A (BPA) degradation gene were quantified via droplet digital PCR. Principal component analysis of the sequencing results revealed distinct clustering of the irrigated and non-irrigated communities at two sites. Control soils from all sites exhibited intrinsic degradation of BPA and ibuprofen. Additionally, several OTUs of the Acidobacteria and Proteobacteria were correlated with soil organic carbon and TOrC degradation. Together, these results suggested that rhizosphere microbial communities were altered in long-term wastewater infiltration galleries, though the impacts of increased soil moisture due to irrigation and the effects of exposure to residual contaminants are difficult to separate. A greater understanding of TWW impacts on soil microbial communities will help expand the prevalence of wastewater reuse for biomass production, contributing to the growth of the circular economy.</p></div>","PeriodicalId":34479,"journal":{"name":"Resources Environment and Sustainability","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666916122000184/pdfft?md5=7bf4f68cf4aab88664258c02b07a718a&pid=1-s2.0-S2666916122000184-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41695175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study aimed to identify erosion hot-spot areas for prioritization of conservation measures and evaluate BMPs for reducing soil erosion using the Soil and Water Assessment Tool (SWAT) model in Ribb watershed, Ethiopia. The SWAT model was calibrated (1995–2002) and validated (2003–2008) using flow and sediment data in the SWAT Calibration and Uncertainty Program (SWAT-CUP). The NSE (Nash–Sutcliffe efficiency), R² (Coefficient of determination), PBIAS (Percent bias) and RSR (Root Mean Square Error — observations standard deviation ratio) values during flow and sediment calibration and validation periods ranged from 0.7 to 0.9, 0.71 to 0.92, -0.4% to 15.2% and 0.32 to 0.55, respectively, indicating that SWAT is able to simulate streamflow and sediment with sufficient accuracy. The calibrated and validated SWAT model was used to evaluate the effectiveness of three BMPs against the baseline conditions for reducing soil erosion, such as filter strips Scenario (Scenario F), stone/soil bunds Scenario (Scenario S) and reforestation Scenario (Scenario R).

The aim of this study was to contribute to the evaluation of chemical properties of soil, crop yields, and the fate of fecal indicators in soil and plants when vegetable crops (lettuces and leeks) are irrigated by drip-irrigation using untreated wastewater (UW), water reuse or treated wastewater by stabilization ponds (TW) and fresh water (FW).
