Your next puffer jacket could be made from bullrushes, as carbon-storing peat farming takes off |
Have you ever wondered what keeps you warm in your winter jacket? Most jacket insulation is made from human made synthetic fibres (polyester) or natural down from ducks or geese. Some winter jackets are insulated with something a little more surprising – bulrushes.
A biomaterials company called Ponda is using the seed heads of bulrush cultivated in peatlands to create BioPuff as insulation for puffer jackets, an alternative to synthetic fibres and goose down. These jackets help to encourage wetter farming on peatlands, a practice known as paludiculture that helps keep carbon locked into the ground.
While paludiculture is a relatively new way of farming in the UK, my research investigates how this emerging farming practice is being implemented in north-west England.
It is crucial that peatlands remain wet or are rewetted to prevent the release of stored carbon. Once drained, peatlands emit a significant amount of carbon – degraded peatlands account for 4% of the UK’s total greenhouse gas emissions. Most (88%) of these emissions come from degraded lowland peatlands, which account for only 16% of the UK’s total peatland land area.
While the complete restoration of lowland peatland habitats is necessary, in many cases landowners and managers........
