About

Simpelpol PP is a free, plain-language guide to polypropylene, the plastic marked PP and the number 5. The name says what we aim for: simple, practical notes on one very common material.

PP is in kitchens, bathrooms, cars, carpets and shopping bags, yet few people know its name. Knowing it helps you look after the things you already own, sort them properly and make sense of the small print on packaging.

What you will find here

• Reading the PP Mark: the resin codes, the symbols beside them and where to find them.
• Reuse & Care: washing, stains, heat and cold, and second lives for old tubs.
• Recycling PP: the sorting routine and what happens at the plant.

How we write

The guides are general and written for households. They do not replace the instructions on a product or the rules of your local recycling scheme, and they do not recommend brands or shops.

What we do not do

We do not make, sell or test plastic products, and we do not offer consultancy for businesses or certify materials.
