How to recycle plastic literally how to melt plastic to make objects?
Answer:
Two real problems must be addressed. The first is sorting the plastic into those of the same chemical type and melting temperatures.
Currently Type 1 PETE used in 2 liter soda bottles is common. Type 2 is also available, but these cannot be melted together.
Plastic from grocery bags, milk containers and pharmacy products are not easily recycled on a small scale.
A controlled heating source is necessary. The plastic can never get too hot or it will begin to decompose. Thermostatically controlled electrical heating elements often work, even with small batches.
Stainless steel in the container of choice. Old batches can be melted out or chipped before new materials are added. You must keep the material moving during the melting process. Mechanical stirring often works well.
Some newer method only use mechanical stirring (a rotating drum) and have the friction of the plastic provide the heat for the melting process. This needs to be pumped out through heated pipes at the end of the cycle.
That's a lot more difficult than it sounds because many commercial plastics have fairly high melting points. Also they are often blends, or they're filled, or painted, or contaminated somehow, or whatever. If you want to make plastic objects you are better off buying some actual resin.
