1 . Recycling is a great way of doing your bit for the environment and helping to protect the earth’s precious resources. However, a new study has revealed that our desire to be sustainable maybe doing more harm than good. According to waste company Biffa, this is because of “wish-cycling” — assuming that items such as disposable coffee cup sand pizza boxes will be recycled if put in the recycling bin. In fact, pollution from those items or other non-recyclables can result in recyclable items that have been put in the correct bin going to landfill. David Heaton, a business director at Biffa, said: “Pollution happens when items are disposed of in the wrong bins or haven’t been cleaned before being recycled.”

Experts at Biffa analyzed the amounts of non-target and non-recyclable materials that entered UK material recycling facilities between 2016 and 2020. It was found that, in 2016, the average pollution rate of recycling waste was 13.4 percent, rising over four years to 17 percent by the end of 2020. This shows that, even as people are becoming more eco-conscious, wish-cycling is increasing both in households and businesses.

The Biffa experts say that one of the best ways to prevent pollution of recycling is to clean recyclable waste before putting it in the bin. They suggest cutting off the top of old pizza boxes and only recycling that part to avoid pollution from the grease (油脂). Check the on-packaging recycling label to check it can actually be recycled When it comes to plastics, Biffa recommends checking the resin code, the number in the plastic triangle, to know whether it should go in the recycling bin. In general, resin codes 1, 2, 4 and 5 are recyclable, while 3, 6 and 7 are not. Larger items, like electronics, furniture and batteries, can also be recycled but often can not go in household recycling bins as they need specialist separating. These will need to be taken to recycling centers or sustainable waste management companies.

“It’s vital as a nation that we get better at effective ‘pre-cycling’— sorting waste correctly before collection to reduce pollution rates,” added Mr. Heaton.

The small numbers may seem insignificant,     3     this temperature increase has had a huge impact globally. Sea levels have risen 15cm in the past century.
