Winner: Bovis Lend Lease
RePlaS proves to be cheaper per square metre than plywood and has the added advantage of being reusable. Alternatively it can be recycled – theoretically as many as ten times before polymer enriching is necessary. The project team are still working on the development of the board and have already come up with a graffiti-resistant version.
Runner Up: Aggregate Industries
This environmentally engineered building block is produced from waste raw materials, with a recycled content of between 72 and 93 per cent. Its contents include recycled aggregate that would otherwise be diverted to landfill, and china clay stent, a by-product of china clay production. The block has achieved an A-rating through BRE environmental profiling.
Runner Up: Green-Tech
GT Greentree is an environmentally friendly and sustainable replacement for increasingly-scarce good quality topsoil. The product has been developed in partnership with Yorkshire Water from organic compost, processed green waste and local quarried sand – substances all previously classified as waste.
Runner Up: Knauf Drywall
Futurepanel is a carbon-neutral plasterboard that contains at least 10 per cent recycled gypsum and 100 per cent recycled paper liner. Manufacturing company Knauf Drywall believes it offers a huge opportunity for the industry to move towards tackling energy costs and Government targets.
Runner Up: Lhoist UK
This bio-composite building material is made from an air-lime based binder with UK grown and harvested hemp shiv, the woody waste material derived from the plant of the same name. It is a low impact sustainable technology that can be mixed on site and using a shuttering system can be spray-applied.
