“…Among them, the indicator ( ), which reflects the solid waste generation of cities, has attracted a significant increase in attention in Chinese cities in recent years. Compared to the management of water and air pollution, many urban areas are facing increasingly severe issues regarding solid waste-management (Lee et al 2021 ). The Chinese government and Anhui province have prioritized solid waste management, issuing a series of central and local policies (Gu et al 2021a ).…”

Inclusive green growth (IGG) offers an effective alternative to pursue sustainable development. The core of the IGG system lies in the coordination of inclusive, green, and growth subsystems. However, there is little quantitative assessment on IGG based on subsystem collaboration. This study proposes a holistic scheme of inclusive-green-growth nexus in Anhui province from 2009 to 2018 by using an integrated approach, namely, the entropy weight approach (EWA), coupling coordination degree model (CCDM), grey prediction model (GPM), and obstacle factor diagnostic model (OFDM). The results show that: (1) The proposed integrated approach could be viable to measure the synergistic interactions among internal IGG subsystems; (2) At the provincial level, a relatively high IGG performance but a low coupling coordination degree (CCD) of the IGG nexus are seen. Although the predicted value of CCD will show an upward trend, it will not be able to cross the start stage. The obstacle factors on the coordinated development of IGG can be divided into two stages: (3) At the prefectural level, the cities in which CCD is rising outnumber those it is falling. However, the CCD is also low, and the gap between cities is getting wider. The obstacles that affect the CCD of cities see a dynamic evolution trend from “inclusive obstacle type” to “inclusive and growth obstacle type” then to “green obstacle type” over the decade.

“…To date, only gasification technologies have been operated on an industrial-scale for such purpose. For example, in Berrenrath from 1993 to 1997 and in Schwarze Pumpe from 1995 to 2007 [40,55,58,59], LWP sorting residues from the dual system served as co-feedstock with coal for syngas generation and subsequent methanol production in Germany. Another prominent example is Showa Denko K.K.…”

“…However, there is a lack of quantitative data and scientific/technical literature to support a comparative evaluation of the strengths and weaknesses of CR against conventional recycling and energy recovery pathways. The predominant attention today -academic and otherwise -is on technical issues related to CR, with existing literature focusing on new technical developments [10,[40][41][42][43], life cycle assessments [23,[44][45][46], as well as energy and material balances [43,47,48]. Furthermore, the predominant focus on pure plastic waste streams as potential CR feedstock has led to significant controversy in the socio-political realm as it presents a direct competition with mechanical recycling techniques [9,49].…”

Chemical recycling (CR) – in enabling the use of plastic waste back as secondary carbon feedstock for production – could play a complementary role to mechanical recycling in supporting the transformation from a linear to a circular carbon economy. To date, research has predominantly focused on assessing technological aspects associated with CR of pure plastic waste streams. Little is known about its potential for treating low-quality and mixed plastic waste fractions which are unsuitable for conventional recycling and are currently incinerated. To address this gap, this investigation utilizes an integrated approach comprising of life cycle assessment and techno-economic analysis to evaluate the environmental and economic performance of CR of lightweight packaging waste via waste gasification compared to direct and indirect incineration in Germany. Results show that CR can contribute significantly – irrespective of the energy mix – to reducing climate change, terrestrial acidification, and fossil resource scarcity. In terms of economic performance, findings suggest that while CR requires higher capital investment, a multi-pronged approach which encompasses upscaling, waiver of carbon dioxide certificate costs, and price premium for CR products could increase profitability of CR to incineration. This study provides empirical support for the potential contribution of CR to complement existing strategies to combat the plastic waste challenge, and insights into market conditions which could promote its economic attractiveness. Additionally, it provides comprehensive inventory data for conventional and alternative waste treatment plants for lightweight packaging waste to inform future research on systemic assessment of CR technologies and their contributions to a circular economy.

“…This synergetic effect would surpass the limit of exhausting end-of-pipe control potential, which will substantially contribute to the long-term air quality improvement (Cheng et al, 2021;. Carbon neutrality goal will also contribute to the mitigation of solid waste and water pollution through promoted low-carbon actions such as the development of circular economy and the construction of "waste-freecity" (Lee et al, 2021;Wei et al, 2021;Bleischwitz et al, 2022). Climate goals to promote the reduction of CO 2 emissions and coordinate the reduction of major pollutants are inevitable choices for China's long-term climate and environmental governance (Tong et al, 2020).…”

China is the largest developing economy and carbon dioxide emitter in the world, the carbon neutrality goal of which will have a profound influence on the mitigation pathway of global climate change. The transition towards a carbon-neutral society is integrated into the construction of ecological civilization in China, and brings profound implications for China’s socioeconomic development. Here, we not only summarize the major challenges in achieving carbon neutrality in China, but also identify the four potential new opportunities: namely, the acceleration of technology innovations, narrowing regional disparity by reshaping the value of resources, transforming the industrial structure, and co-benefits of pollution and carbon mitigation. Finally, we provide five policy suggestions and highlight the importance of balancing economic growth and carbon mitigation, and the joint efforts among the government, the enterprises, and the residents.
