Silicone has many benefits over plastic, which is well-known to be enviroenmentally distructive. Firstly, silicone is made from silica, which comes from sand. In comparison, plastic is made from crude oil, which requires extraction from the ground. Secondly, unlike plastic, silicone does not break down into micro-plastics that end up in the ocean, and it is recyclable. Thirdly, a major environmental benefit of silicone is that it is not made for single use. Silicone is hardy and durable, so it can be used over and over again. Its resistance to heat and cold also means you don’t have to worry about it cracking or melting.
