·[ Sustainable Concrete Aggregate.

While contemplating material choices to separate the different zones of the factory; production, storage, research, and retail, I had a thought regarding how the industrial, polished concrete floor and basement storage could be customised. Looking at the makeup of the land beneath the region, there is only sandstone and clay, no real rock, so I thought about finding other aggregate sources in the area. The animal carcasses in the nearby fat rendering plant will produce a lot of bones as the fat is stripped from them. Perhaps the bones can be crushed, and used as a natural aggregate, producing an economical, ecological and individual finish.

Upon researching the idea, it has already been looked at in theory, and in the tests done, has been shown to be a viable alternative to rock:

  • Abstract:An exploratory study on the suitability of the machine crushed animal bones as partial or full replacement for normal coarse aggregates in concrete works has been carried out. Physical and mechanical properties of machine crushed animal bones and locally available normal aggregate have been determined and compared. A large number of concrete cubes of size 150×150×50 mm with different percentages by weight of normal aggregate to crushed animal bones as coarse aggregate in the order 100:0, 75:25, 65:35, 50:50, 25:75 and 0:100 were cast, tested and their physical and mechanical properties were determined. Compressive strength tests showed that approximately 50% of the crushed animal bones in replacement for normal aggregate were quite satisfactory with no compromise in compressive strength requirements for concrete mix ratio 1:1.5:3. The study has been carried out at 25%, 35%, 50%, 75%, and 100% replacement levels of normal aggregate by crushed animal bone (CAB) aggregate by weight and a comparative study has been done between normal concrete and crushed animal bone (CAB) concrete.


A Designer also used bones to make various fashion and household accessories, to try and find a use for Materials we are no longer using:

Cow bones used to be ground up for animal feed but the process was outlawed after the BSE crisis, and now truckloads of bones are thrown away every day.
