Sourcing (Where to find materials for cob)
The CobBauge Project
COB is a mixture of earth, natural fibre and water - with earthen and COB houses making up about ⅓ of the total dwellings globally. Plymouth University, with the help of earthen construction partners in France and Europe, attempted to create four new COB mixtures from local soils as a proof of concept for COB being thermally and structurally sound enough to meet building regulations and significantly improve household energy efficiency.
The newly created cob mixes will be produced from local soils, helping to reduce CO2 emissions by around 40 per cent compared to the production of traditional masonry materials. They will also reduce construction waste by a projected 16 tonnes per property, a saving of €2115 in terms of landfill costs.
