Energy-intensive manufacturing is a major source of GHG emissions and environmental impacts. Countries in the world are all facing challenges in green manufacturing transformation. The conceptual evolution and actual implementation of green manufacturing in China and other countries show some similarities but also discrepancy. This paper describes the green manufacturing system in China from four aspects:

End-of-life (EOL) electric vehicle (EV) batteries can be remanufactured into second-life batteries (SLBs) for residential and utility-level stationary storage applications. However, it is important from a sustainability perspective to assess that there is no increase in material requirement, cost, or carbon footprint of lithium-ion batteries by adding a remanufacturing stage before recycling. A system

Different from plastics recycling policies in many European countries, the German Dual System aims to provide a comprehensive regulatory system for post-consumer plastics recycling. Our paper analyses, how the interplay of actors and regulations shaped market processes in that system. Based on 18 expert interviews, we discuss, how institutional factors influenced the system outcome at the level of

Demand for critical materials (nickel, cobalt, manganese [NCM], and lithium) for use in batteries is increasing rapidly due to the expansion of the battery-electric vehicles market. Battery metal recycling (BMR) is an important technology that can potentially realize environmental and economic benefits in cathode active material (LiNixMnyCozO2) production using recycled materials. While current major

The eutrophication of water bodies caused by the release of treated wastewater rich in total phosphorus (TP) is a worldwide problem. In this work a full-scale wastewater treatment plant (WWTP) was developed with an enhanced biological removal of phosphorus (EBPR) process for the TP removal in wastewater, despite high levels in raw effluent. The microbial community involved showed a low number of polyphosphates

We evaluated the battery material demand and GHG emissions implications from high EV and very aggressive Plug-in Hybrid EV (PHEV) penetration rates for the U.S. light-duty vehicle fleet from 2020 to 2050. If the U.S. relies primarily on EV deployment to decarbonize passenger transport, there are potentially significant supply constraints over the next decade, particularly for cobalt, lithium, and nickel

Repair is advocated as a circular strategy to improve the environmental performance of products. Whether this holds for very long-lived and energy intensive products has not been addressed. This study compares environmental impacts of two high voltage motors of different energy efficiency and assesses their use extension by repair with life cycle assessment (LCA). Due to high energy use, long lifetime

Carbon dioxide removal (CDR) could change terrestrial carbon uptake due to biosphere responses. Here we examine the seasonal and regional responses of net biome productivity (NBP) and its components to carbon emissions reduction under the SSP5–3.4 overshoot scenario simulated by eight CMIP6 Earth system models. Globally averaged NBP is lower under SSP5–3.4 than under SSP5–8.5, with 102±7 Pg C (51%)

Reducing environmental impacts related to resource use has been considered a significant challenge for sustainable development, but methodologies to assess national level impact decoupling have not been established adequately. For this, an economy-wide eco-efficiency analysis of Japanese material production and a decomposition analysis are conducted. Combining data from the Japanese life cycle inventory

Intervention policies are a major but underrecognized way of reducing food waste. This study developed a new methodology for assessing the effectiveness of food waste policies, based on the analysis of 874 policies (1955–2021) and eight different types of entire food supply chain waste (1961–2021) in China, further modeling by support vector regression machine to predict the amount of food waste for

Although charging infrastructure is a prerequisite for widespread electric vehicle (EV) penetration, its deployment is prone to a "chicken-egg" dilemma in the early stages of electrification. Previous studies mainly applied game theoretical approaches to identify the optimal strategy for escaping the dilemma, with minimal attention paid to the complex interactions between EV adoption and charging infrastructure

In two 5-week randomized-controlled field studies, Canadian and US households were invited to make one meal per week from food that might otherwise be discarded, using flexible recipes. In the first study (Canada), tools to increase the salience of unused food (storage basket, clips to tag, or whiteboard) were also explored. A second study (US) examined a shorter program and the addition of follow-up

In African countries, limited knowledge about the co-production of water, energy, and food (WEF) resources and their sectoral interaction makes it problematic to define sufficient policy options to ensure their efficient and sustainable production. This study proposes a new approach to assess the WEF sectors' co-production in 47 African countries from 2000 to 2020. The study shows low and varied co-production

Lean asphalt is a hot mixture produced with a lower binder content than a conventional dense-graded mixture. When used as a base layer, it allows for high RAP content and increases the structural capacity of the pavement compared to an unbound base. However, its low binder content and relatively high air void content raise concerns regarding its performance. This study found that about 40% RAP content

Lithium-ion batteries (LIBs) can help support sustainability through electric vehicles and energy storage. There is now wide adoption of LIBS and supply sourcing concerns for LIB metals such as cobalt and lithium. LIB End-of-life (EOL) management is essential for LIB metals supply chain resilience. Safety risks within EOL LIBs are potential disruption concerns. In this study safety risks during LIB
