Reducing Waste in the Fresh Produce Supply Chain

Summary of the impact

Cranfield's work on ethylene supplemented storage is now exploited in the supply chains to major supermarkets in the UK, including Waitrose and Tesco, reducing waste and avoiding volatility in supply for fresh food products such as onions and potatoes. By prolonging storage life by up to six weeks it is also having a positive impact on the UK's self-sufficiency in these products, displacing imports from overseas.

Complementary work has also led to commercial ethylene scrubbing technologies for packaging, which typically save around 50% of in-store waste and add two days to the product life for a range of fruit and vegetables. Such packing is now in use in most mainstream UK supermarkets, and in the USA where it has created a new export market for the manufacturer.

3) GRANIT

Summary of the impact

The GRANIT system is a non-destructive technique for assessing the condition of rock bolts and ground anchors used to support structures such as tunnels. It applies a small impulse to the bolt and interprets the resulting vibration response to provide estimates of load and unbonded length. Initial development of the system was based on the findings of EPSRC projects in tunnels undertaken by the Universities of Aberdeen and Bradford from 1989-1997, resulting in an empirically based method. However, research undertaken at the University of Aberdeen since 1998 has provided the understanding of the process and developed the fundamental engineering science needed to underpin the development of a full commercial system. The GRANIT system is patented, and has been subject to worldwide licence to Halcrow who have undertaken testing and provided a method of ensuring the safety of mines, tunnels and similar structures. Halcrow received the NCE award for Technical Innovation Award for GRANIT in December 2010. The impact of the research has been in part economic, but largely on practitioners and professional services.
