The plastic flakes are then dried in a tumble drier, and are melted afterward in a machine called an extruder , where heat and pressure melt the material. Because there different types of plastic, each variant at different temperatures.

It can also provide a suitable income-earning potential for those who wish to engage in collecting and selling recyclable materials. Among the most commonly-recycled materials include glass, plastic, textiles, electronic components, aluminum, cardboard and scrap metal.

Recycling Saves Energy According to data from the US Energy Information Administration, a paper mill actually uses 40 percent less energy to make paper from recycled materials, than it does to make paper from freshly-cut lumber. Proponents of recycling also tress that the need to use a second timber or logging truck is defrayed when paper is collected and used for recycled. Old computer monitors for example contain as much as eight pounds of lead. Once these harmful substances leach into the soil and underground water, they further spread and contaminate streams, rivers, and water wells, and also taint the fish and other seafood we consume.
