Plastic represent thousands of materials with different physical, mechanical, and chemical properties. As plastic demand usage increase, it is undeniable that the amount waste will increase. has features which cannot rot; does not decompose naturally; absorb water or rust. So eventually cause problems for environment. This study aims to determine compressive strength tensile concrete mixes use ...

ith more than 8 million tons of plastic entering the ocean each year, humanity must urgently rethink the way we make and use plastics, so that they do not become waste in the first place. Cheap, light, and versatile, plastics are the dominant materials of our modern economy. Their production is expected to double over the next two decades. Yet, only 14% of all plastic packaging is collected for...

One of the most ubiquitous and long-lasting recent changes to the surface of our planet is the accumulation and fragmentation of plastics. Within just a few decades since mass production of plastic products commenced in the 1950s, plastic debris has accumulated in terrestrial environments, in the open ocean, on shorelines of even the most remote islands and in the deep sea. Annual clean-up oper...

The glycolysis of postconsumer polyethylene terephthalate (PET) waste was evaluated with catalysts of zinc acetate, zinc stearate and zinc sulfate, showing that zinc acetate was the most soluble and effective. The chemical recycling by solvolysis of polylactic acid (PLA) and PET waste in either methanol or ethanol was investigated. Zinc acetate as a catalyst was found to be necessary to yield a...

The problem of plastic waste that needs to be handled and managed optimally can cause environmental damage. This study aims test the compressive strength water absorption value paving blocks made which are designed using a mixed variation V50-50 (50% sand, 50% plastic), V25-75 (25% 75% plastic) V0-100 (0% 100% total proportion mix. method is carried out by melting PP (Polypropylene) mineral gla...

Waste plastic, both industrial and municipal sources, is posing a major environmental challenges in developing countries such as India due to improper disposal methods. Large quantities of non-recyclable plastic waste get collected in paper recycling plants in Muzaffamagar and other regions in India. The plastic waste is typically in the form of protective covers, thin film, binding coils etc.,...

The effect of fuel composition on gasification process performance was investigated by performing mass and energy balances on a pre-pilot scale bubbling fluidized bed reactor fed with mixtures of plastic waste, wood, and coal. The fuels containing plastic waste produced less H2, CO, and CO2 and more light hydrocarbons than the fuels including biomass. The lower heating value (LHV) progressively...

Plastic waste disposal is a significant environmental concern due to its low degradability and management practices, especially in developing countries. recycling considered the most effective method, which minimizes impacts. This paper discusses use of poly(ethylene terephthalate) (PET), high-density polyethylene (HDPE), polypropylene (PP) plastic as aggregates concrete industry by incorporati...
