This week Wales has joined England and Scotland on waving goodbye to single-use plastics. The decision lends its hand to the 'booming' compostable packaging industry.

But could a packaging that reverts to nature be too good to be true? One UCL study has found that 60% of products advertised as home compostable didn't fully decompose within 12 months - and a lot of consumers don't know which bin they go in.

So are compostables genuinely a good alternative to plastic?

On Sky News ClimateCast Tom Heap visits a compostable packaging manufacturer to find out how it works and where it's best fit for purpose.

He meets researcher Danielle Purkiss who ran the Big Compost Heap study to find out what the challenges with this kind of packaging are and visits online grocer Abel & Cole - who've decided to ditch compostables.
