Due to Ministry of Environment (MOE) plays an important role to resource recycling and zero-waste strategy for responding to 2050 net-zero emissions, according to the developed trends from all the ministries, the National Environmental Research Academy plan a technical blueprint for the development of resource circulation and net-zero emissions with short- and medium-term goals.
MOE has promoted the solid recovered fuels (SRF) and recycled materials for years, and as the regulations from Intergovernmental Panel on Climate Change (IPCC), the carbon dioxide emissions generated from biomass combustion can be neglected. This project collected 30 SRF samples and evaluated the method accuracy and precision by ISO 21644:2021. Due to 14C shows the highest accuracy in the assessment, this plan employed the results of biobased carbon content results and Life Cycle Assessment methods to evaluated the carbon reduction benefit of SRF, two different types of domestic SRF carbon footprint. Base on this method, the carbon reduction benefit of SRF primarily composed of waste plastics is 9.6%, and that for SRF with a mixture of plastics and textiles is 27.5%. Moreover, this project also evaluated the feasibility of recycled content verification technology for recycled plastics and recycled fibers with pervious literatures. The projects collected virgin PET resin, recycled PET resin and three different types of recycled plastic products to test the recycycled PET contents with BSI Flex 6228: v2.0. The results demonstrate that it is possible to determine whether PET resin pellets or plastic products contain more than 30% recycled PET material, and the accuracy up to 85%.
To achieve the purposes of carbon reduction and environment friendly, this plan established the correlation between chlorine content of fuels, combustion temperature of boiler and persistent organic pollutants (POPs) generation based on the emission characteristics (e.g. stack, ash, residues and effluent) of samples collected from 7 burning scenarios. The results show the stack emission for all samples are confirm to Small and Medium-Sized Waste Incinerator Control and Emission Standards. The two cases derived ash reached Standards for Defining Hazardous Industrial Waste(operator has already legally declared it as C-0120), which reason is likely realted to the combustion gas temperature in the downstream part of incinerator's secondary air injection is lower than 850℃.
