We all agree that we should recycle more — at home, in the office or when out and about. But for materials to be recycled, they first need to find their way to the right waste stream. 1. This is what the process of sorting allows us to do.

For effective recycling we need effective sorting. And this needs to happen first, in our own home and second, in sorting plants to which waste collected from our doorstep is taken. When you put a plastic bottle in the right recycling bin, you are helping sort recyclables. So the right material can be fed into the right recycling process. 2. They can be a loss of valuable resources from our economy.

3. For instance, in Brussels, Belgium, consumers put plastic packaging, cans and beverage cartons in blue bags designed for recyclable packaging; paper in yellow bags for recycling; and glass needs to be taken to specific collection bins. Somewhat differently, in Vienna (Austria), citizens can expect their paper, metal, glass and plastic to be separately collected in different weeks of the year. 4. In this way, they can sort their recyclables at home more effectively.

Once recyclable materials are collected from your doorstep, they are further sorted in specialized facilities which ensure the quality of the recycling process. 5. Traditionally, sorting has been done either manually with workers sorting what can be recycled and picking out the materials to be discarded or mechanically. Today, however, new technologies are being developed in order to speed up the process of sorting but to also yield better results. Exciting technologies using magnets or optical systems are being used to effectively sort materials so more of it can be recycled.

A.If sorting doesn't happen, recyclable materials can end up in landfills.

B.This is where different sorting techniques come into play.

C.In Europe, collection systems vary from country to country.

D.So citizens need to be aware of their local collection system.

E.Then they can be collected and taken to the right place for recycling.

F.The rest, though they could be recycled and reused, were landfilled or burned.

G.In recent years, Europe has seen a 25% growth in recycling secondary raw materials.
