Reducing the environmental impact caused by plastics can be addressed through different strategies, such as the manufacture of more durable plastics or recycling. In general, there are two main types of plastics. The first is thermoplastics, which can be melted and molded to form other objects, although their mechanical properties weaken if they are melted several times. And the second, thermosets, do not melt at high temperatures, since the chains of the polymers that form them are intertwined by chemical bonds.
