Chlorinated plastic can release harmful chemicals into the surrounding soil, which can then seep into groundwater or other surrounding water sources, and also the ecosystem. This can cause a range of potentially harmful effects on the species that drink the water. Plastics have several toxic constituents among which are phthalates, poly-fluorinated chemicals, bisphenol A (BPA), brominated flame retardants and antimony trioxide which can leach out to have adverse effects on environmental and public health. Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process. Plastics are derived from natural, organic materials such as cellulose, coal, and natural gas, salt and, of course, crude oil. Recycled LDPE showed low tensile strength and elongation at break compared to virgin LDPE. Meanwhile, the stiffness properties of recycled LDPE increase after the recycling process. Mechanically recycled plastics will commonly undergo chain degradation due to high temperature and shear effects.

Plastics are made from natural materials such as cellulose, coal, natural gas, salt and crude oil through a polymerisation or polycondensation process. Plastic products contain chemical additives. A number of these chemicals have been associated with serious health problems such as hormone-related cancers, infertility and neurodevelopment disorders like ADHD and autism.

Mechanical Properties of Recycled Plastics

Chapter Mechanical Properties of Recycled Plastics

Plastics have several toxic constituents among which are phthalates, poly-fluorinated chemicals, bisphenol A (BPA), brominated flame retardants and antimony trioxide which can leach out to have adverse effects on environmental and public health. Recycled LDPE showed low tensile strength and elongation at break compared to virgin LDPE. Meanwhile, the stiffness properties of recycled LDPE increase after the recycling process. Mechanically recycled plastics will commonly undergo chain degradation due to high temperature and shear effects. Recycled plastics are used to create all sorts of items, such as packaging, bags, car components, furniture, building materials, paint pots and even kerbstones. Plastic sticks around in the environment for ages, threatening wildlife and spreading toxins. Plastic also contributes to global warming. Almost all plastics are made from chemicals that come from the production of planet-warming fuels. Plastic takes several years to decompose, it is not environment friendly. It causes environmental pollution. Besides, the burning process in the synthetic material is quite slow and it does not get completely burnt easily. Plastic is a poor conductor of heat and electricity. Plastic does not react with air and water and with many of the chemicals. Plastics are light weight, durable, cheap and very strong. Plastics are non- biodegradable substances.
