Waste plastic mounting, but can be recycled into other products in the form of granules before further processed into pellets and seed injection molding process produces products such as buckets, plates, bottles and other beverages. To be processed into the required form of granules of plastic thrasher. Though so small plastic recycling industry is still constrained in plastic enumeration process because the machine used was not optimal ability. The purpose of this research is the development of the system thrasher plastic crusher and cutter cylinder-type reel and technical evaluation. This study was conducted over two years, the first year the design and manufacture of machinery, the second year is a technical evaluation of the engine, engine performance improvements and economic analysis of granular plastic products.From the results obtained engine design capacity of the machine ± 350 kg / h, the engine size is 50 cm x 120 cm x 30 cm, power motor of 10 HP at 1450 RPM rotation with 3 phase. Some of the major components of the engine that is, counter crusher unit consists of two counter rotating cylinders opposite, counter shaft size Ø 4 cm x 58 cm, blade chopper Ø 17 cm x 2 cm with the number of teeth / blades 7 pieces and the number of blades along shaft 7 pieces, buses retaining Ø 10 cm x 2 cm. Counter-cylinder unit consists of a reel-type cutter counter shaft size Ø 4 cm x 90 cm, the middle shaft mounted cylinder with Ø 17 cm x 40 cm as the holder of the chopper blades. Chopper blade consists of 4 pieces with a size of 40 cm x 2 cm x 4 cm with ASSAB materials. Furthermore, as the blade retaining bedknife shear force of the blade chopper, upper frame, lower frame, strainer, funnel entry, exit funnel, and the drive unit consists of an electric motor, reducer, belts, pulleys and 2 pieces of gear transmission. The results of performance testing machine crusher round cylinder 75 RPM and 1450 RPM reel-type cutting machine capacity ± 300 kg / h on the filter hole Ø 1.5 cm, with a 80% grain uniformity.

AbstractOver 359 million tons of plastics were produced worldwide in 2018, with significant growth expected in the near future, resulting in the global challenge of end-of-life management. The recent identification of enzymes that degrade plastics previously considered non-biodegradable opens up opportunities to steer the plastic recycling industry into the realm of biotechnology. Here, we present the sequential conversion of polyethylene terephthalate (PET) into two types of bioplastics: a medium chain-length polyhydroxyalkanoate (PHA) and a novel bio-based poly(amide urethane) (bio-PU). PET films were hydrolyzed by a thermostable polyester hydrolase yielding 100% terephthalate and ethylene glycol. A terephthalate-degrading Pseudomonas was evolved to also metabolize ethylene glycol and subsequently produced PHA. The strain was further modified to secrete hydroxyalkanoyloxy-alkanoates (HAAs), which were used as monomers for the chemo-catalytic synthesis of bio-PU. In short, we present a novel value-chain for PET upcycling, adding technological flexibility to the global challenge of end-of-life management of plastics.Graphical abstract

In the last three decades, the increased use of plastics is rapidly becoming a global environmental issue, resulting in growing landfills, pollution of surrounding atmosphere, and possible greenhouse effect. The automotive industry, as a major demander of plastic materials, is starting to take responsibility on sustainable actions. Japan, as the world’s top tier car manufacturing and dealing country, has been taking attempts to the proper dealings of used auto-plastic. This research aims to find out current situation of auto-plastic recycling industry after these attempts. Furthermore, this research compares pros and cons of each treatment and methods under treatment environmentally as well as economically from the point of recycling operators using life cycle assessment. Bumper is chosen as the target to represent auto-plastic because of their homogeneity of composition and relatively large share of weight among all auto-plastic parts. The result shows that material recycling amount is decreasing along with recent promotion demonstration. Top reason is that material recycling even reduces carbon emissions, costs far more than energy recovery, and that subsidy is given to energy recovery but not material recycling worsens the situation. Besides that, lack of cooperation between stakeholders on the demand of secondary plastic is impeding material recycling. Also, better scheme on how to separate auto-plastic and what kind would be separated should be noticed by the policymaker.

Inappropriate plastic packaging design with excessive use of color and printing ink affected to the high cost of sorting, separation and cleaning, and low acceptance level of plastic waste for secondary recycling. This research proposed design for material value conservation which elaborated with a set of design criteria for rigid plastic packaging production as key solution in avoiding value degradation of the plastic waste. The existing design criteria of products have various approach which affected on how to manage abundant plastic waste with no or very low value of materials that has been generated by daily consumption of plastic packaging. Otherwise, the proposed design criteria conserve the material value systematically which make the post use materials of plastic packaging more financially feasible as raw materials in plastic recycling industry. Widespread implementation of the new design criteria in industry will generate broader impact and more benefits in economic, social and environment, especially for countries or regions with high density of people and high consumption rate of conserved products.

Plastic Pellets

The high use of plastic products is currently causing uncontrolled accumulation of plastic waste so that an effort is needed to minimize the negative impacts caused to the environment. One of the appropriate efforts in processing plastic waste is recycling to produce a variety of useful products. Each stage of the process in managing plastic waste recycling starts from collecting raw materials to producing a new product for consumers requiring energy that can be calculated and analyzed for their impact on the environment using the LCA method. From this study can be concluded that the plastic recycling industry as one of the efforts in reducing the generation of plastic waste to the environment consists of 3 (three) main stages, namely the stages of enumeration, the distribution of raw materials and the stages of production of plastic pellets. The environmental burden analyzed includes the production process of recycling plastic waste to produce an output in the form of 1 ton of plastic where the total GHG emissions generated are 2.36E + 03 kg CO2 eq, with details of the potential contribution to global warming of 1.30E + 02 kg CO2 eq at the stage enumeration, 3.52E + 01 kg CO2 eq at the distribution stage and 2.15E + 00 kg CO2 eq at the plastic pellets production stage. The efficiency of plastic seed products in this study showed a good result, where the NEV and NER values of the recycled plastic pellets products were 39664.1 MJ and 2.11 MJ.
