    Food waste reduced by processors changing testing

    Food waste reduction is key to saving money, improving food production efficiency, lowering greenhouse gas emissions, reducing packaging waste and protecting the environment. Dr Abdel Ezbiri from the technology company Cerulean discusses the waste that results from the temperature testing of fresh and chilled foods, and outline the success that some food processors have achieved in adopting non-destructive testing (NDT) technology.

Hydrogen additive technology slashes engine emissions 

British manufacturer CGON has released a revolutionary new range of hydrogen additive products that can reduce engine emissions by up to 80% and offer fuel savings of up to 20%.

CGON ezero1Developed over the last eight years at its research and development facility in the United Kingdom and tested extensively on the road, CGON's independently verified technology significantly reduces emissions such as CO2, HC, NOx, PM and PN.

The 100% recyclable ezero hydrogen additive box is fitted within the engine bay and can be used on any fossil fuel engine, from petrol to diesel to LPG.

The system works by introducing small amounts of very pure, very powerful hydrogen directly into the inlet chamber where it combines with the fuel-air mixture. The resulting hydrogen-fuel-air mix – which has a cooler burn that's faster than a conventional mix – creates a more complete combustion cycle.

The result is that almost all waste gases are eliminated, drastically reducing harmful emissions. And because CGON's technology increases engine efficiency, less fuel is used, with real-world drivers reporting savings of up to 20%.

The initial idea for the technology came from founder Brian Sheard, a Royal Navy Engineer on nuclear submarines (https://www.cgon.co.uk/OurStory).

CGON's ezero products don't store any hydrogen onboard at all but create small amounts on-demand. The ezero box is topped up every 6,000 miles with CGON's patented electrolyte solution (a 250ml pouch of electrolyte costs £5). CGON produces three different variants of the ezero range, from the ezero1 aimed at smaller engines used in passenger cars and vans, with the ezeroH1 targeted at larger vehicles such as small coaches and light goods vehicles in the 7.5-tonne range, all the way up to the ezeroH2 model for the HGV and bus market.

The company's consumer product, the ezero1 has been independently tested on the road by Emissions Analytics. For the urban drive cycle, independent PEMS testing has shown reductions of 91.3% in PN (Particulate Number, or soot) plus a 47.9% reduction in NOx and a 50.6% reduction in NO2. The ezero1 can be fitted to any internal combustion car in approximately one hour. The box costs £459 including VAT and fitting. The CGON cells have a 12-month guarantee.
