The researchers estimate that the British sidestream testing program has produced enough plastic waste to fill 200,000 bathtubs or 19 Olympic swimming pools.
Scientists from the Institute for Energy and the Environment at the University of Hull argue that once we learned that Covid-19 spreads more through the air than through surfaces, the UK government should have started recycling tests to avoid unnecessary plastic pollution.
The government says it has already made changes to make the tests more robust. But did we have to recycle our sidestream test kits?
BBC Health correspondent Laura Foster, who has collected waste from all her sidestream tests, explains the situation in two minutes.
