Life Cycle Analysis on Regenerating and Energy Recovery of Plastic Solid Waste Management in Shanghai

Abstract

Over the past several decades with significant technological advances there has been continuous increase in plastic manufacturing in China, which has contributed to the production of a great deal of plastics worldwide every year, and at the same time it has resulted in a large amount of plastic solid waste (PSW). It has great potential values for waste plastics to reuse as secondary materials, which may lessen pressure on resource and environment. The paper studies the status of waste plastics in recycling, reusing and reducing on management countering on the increase in the flow of waste plastics in Shanghai. In light of the methodology of life cycle, the study analyzes the environmental impacts associating with the alternatives in a ‘cradle to grave’ approve to PSW technological recycling systems. We will choose regenerating and energy recovery processes based on site investigation and literatures data in Shanghai to analyze recycling options and how various processes affect the environment. Life-cycle methodology was very suitable for evaluating the overall environmental consequences, and could be used for making decisions and planning strategies with the rapid increase of plastic solid waste generation for Shanghai.

Regeneration and Recovery of Plastics

“…The environmental impacts associated with the alternatives for PSW technologies for the various recycling systems along with regenerating and energy recovery processes are used to analyze recycling options and the environmental effects. LCA is found to be most suitable for evaluating the overall environmental effects for regeneration and energy recovery from plastic solid waste for Shanghai ( Zhou et al ., 2015 ).…”

Identifikasi Mikroplastik Di Udara Pada False Solution Technology

“…Pengolahan sampah dengan false solution technology tersebut di samping memiliki keuntungan, ternyata juga memiliki kekurangan terhadap lingkungan. Seperti menghasilkan karbon monoksida (CO) ketika pembakaran sampah tidak sempurna dan karbon dioksida (CO ), gas 2 Cl (Jasmine & Hermana, 2020), emisi SO 2 x yang bisa mengakibatkan hujan asam dan NO (Tabasová et al, 2012 ;Zhou et al, 2015), X menghasilkan Polychlorinated dibenzodioxine and furans (PCDD/F, dioxins) yang sangat toksik yang termasuk dalam kelompok senyawa pencemar organik persisten. Selain itu juga menghasilkan gas CH , NH , HCl, HF dan menghasilkan 4 3 residu berupa partikel mikroplastik (Warner & Lambert, 2018), dan cemaran logam berat (Tabasová et al, 2012), serta dapat berdampak pada PM 2.5.…”
