How do plastic products begin?

Have you ever wondered how plastic products are made? They begin as a petroleum liquid or gas, and are turned into these pellets or microbeads below:

These pieces are about the size of a rice kernel, and the few black ones in this batch will make the whole mix that colour. Because of the size of the beads, they’re easy to melt and then mould into something useful.

Now imagine shipping containers full of these microbeads spilling into the ocean. This unfortunately has happened too many times, leaving the beaches and sea floor like this picture below:

The reality is that any plastic product will eventually break back down into these rice size pieces and even smaller over time. Yet, it will be centuries before they can degrade back to petroleum.

This is why there’s so much talk about plastic in the news these days. This is not new knowledge. It’s just that the physical impacts to our environment and wildlife have finally reached such high levels that it’s hard to ignore.

Plastic isn’t a bad product by itself. It’s light, durable, flexible, and lasts forever – the same traits that are also causing harm to Mother Nature. The challenge for product manufacturers is to design their goods for the full cycle of life, not just the making stage.

If everyone thought about the disposal of the product and not just the making and using stages, they would probably make it very differently.
