Residual municipal solid waste to energy under carbon neutrality: Challenges and perspectives for China

Fine Regeneration of ABS and PS Plastics from Waste Refrigerators through Mechanical Physical Recycling

“…guidance of a carbon neutrality strategy, the recycling and utilization of carbon-based substances is an inevitable trend towards achieving sustainable social development. 25,26 Therefore, it is crucial to conduct in-depth discussions on the recycling and utilization technology of waste plastics. 27 Advanced physical recycling technology refers to the process of crushing, cleaning, and separating through physical methods to obtain pure plastic flakes.…”

“…Assuming a weight of 70 kg per refrigerator, the potential recycling capacity of ABS is expected to reach 630 000 tons by 2035, which is a potential renewable resource. Under the guidance of a carbon neutrality strategy, the recycling and utilization of carbon-based substances is an inevitable trend towards achieving sustainable social development. , Therefore, it is crucial to conduct in-depth discussions on the recycling and utilization technology of waste plastics …”

Technology Innovation in Incinerator Fly Ash Sintering and Melting Brings Regional GHG Mitigation and Economic Benefits

“…Under the context of the "zero-waste city" plan and "carbonneutrality" policy in China, solid waste management urgently needs a low-carbon development path and technological innovation. 29 Recommending appropriate IFA management options for regions with high GHG emissions given the different GHG emission profiles and eco-efficiency in each province will be meaningful in accelerating the achievement of carbon peak and carbon neutrality targets nationwide. 30 The analysis of GHG emission driving factors in the Yangtze River Delta region shows that energy conservation technologies have significant GHG mitigation potential.…”

“…Moreover, the environment and economy will be positively impacted if the Sec-FA is reused in areas where fuel melting is applied. The findings of Song et al suggest that with the arrival of China's carbon peak,29 technology substitution and energy efficiency improvement have become effective paths to reduce GHG emissions. The government should strengthen cooperation with universities and research institutions to develop new resource utilization processes and equipment tailored to different regions in China, accelerating the updating and upgrading of key technologies for IFA reutilization.Regional Environmental and Economic Gains from Technology Recommendation and Innovation.…”
