Prevention and recycling of waste
The best waste is the kind that is never created.
Waste creation can be reduced through material efficiency, that is, sparing use of materials and environmentally responsible purchases, taking into account recyclability from the start.
The key decisions regarding waste generation are made when products are purchased. It is at that point that the decision is made whether you want to have disposable or durable products, individually packaged products or bath products, products made from recycled materials etc. Packaging waste can be reduced by, for example, buying products in larger batches or favouring products whose packaging is returned to the importer or wholesaler for reuse.
Perho CTBC sorts waste into eight components. The entire staff and all students are committed to waste sorting and recycling.

Energy waste = Mixed waste
Helsinki Region Environmental Services Authority (HSY) stopped collected energy waste in April 2016. Energy waste can now be placed in mixed waste. Mixed waste (energy waste) consists of plastic packaging, disposable containers, styrofoam waste etc. Plastic products (indicated by codes 01, 02, 04, 05 and 06), plastic packaging used for food and other products, plastic bags, styrofoam, CD/DVD discs. This waste is burned in thermal power plants or industrial plants. Within Helsinki, mixed waste is taken to the Vantaa incinerator power plant. Energy waste can be incinerated. At the Töölö and Malmi campuses, we only collect mixed waste.
