Resource Efficiency and Carbon Footprint Minimization in Manufacture of Plastic Products

Efficient resource management, waste prevention, as well as renewable resource consumption promote sustainable production and lower greenhouse gas emissions to the environment when manufacturing plastic products. The paper presents the analysis of the efficiency of resources and the potential of carbon footprint minimization in manufacture of plastic products by means of implementation of wood-plastic composite (WPC) production. The analysis was performed using life cycle assessment and material flow analysis methodology. To devise the solution for better management of resources and minimization of carbon footprint, the environmental impacts of polyvinyl chloride (PVC) and WPC wall panels through their life cycle were assessed, as well as the detailed material flow analyses of the PVC and WPC in production stages were carried out. For better resource efficiency, the conceptual model of material flow management has been proposed. It would lower environmental costs and environmental impact, increase the efficiency of resources, and diminish dependence on suppliers.Original Abstract: Efektyvi istekliu vadyba, atlieku prevencija, atsinaujinanciu istekliu naudojimas skatina darnia gamyba ir mazina Siltnamio efekta sukelianciu duju issiskyrima plastikiniu produktu gamybos sektoriuje. Straipsnyje yra pristatoma efektyvaus istekliu panaudojimo ir anglies dioksido (CO sub(2)) pedsako mazinimo galimybiu analize, diegiant medzio ir plastiko kompozito gamyba. Analize buvo atlikta taikant buvio ciklo vertinimo ir medziagu srautu analizes metodikas. Efektyvaus istekliu naudojimo ir anglies dioksido pedsako mazinimo galimybes buvo vertinamos nustatant gaminiu is polivinilchlorido (PVC) ir medzio ir plastiko kompozito (angl. wood-plastic composite - WPC) buvio cikla ir detaliai analizuojant gamybos proceso medziagu) srautus. Vertinant gaminiu buvio cikla, buvo nustatyta, kad 1 kg WPC dailylentes CO sub(2) pedsakas per visa gaminio buvio cikla yra 37 proc. mazesnis negu to pacio svorio PVC dailylentes. Abieju produktu didziausias poveikis aplinkai susidaro vykstant gamybai, taciau cia WPC dailylentes CO sub(2) pedsakas yra 35 proc., o vykstant salinimui - 47 proc. mazesnis negu PVC dailylentes. Medziagu srautu analizes rezultatai parode, kad perdirbus broka ir dar karta ji panaudojus, maziau sunaudojamos antriniu PVC ir pirminiu WPC zaliavos tam paciam produkcijos kiekiui pagaminti. Taip pat imone pletoja pramonines ekologijos koncepcija, nes bendradarbiaujant su statybu s
