Endorsements

Independent studies validate VWP technology:

Universities of Cranfield and Coventry, UK and PERA have studied and analysed the results of this technology. The studies outline the effectiveness of VWP in waste treatment and converting waste into useful end products like soil enhancer, bio-ethanol, pellets, briquettes etc.

The key observations from these independent studies are summarized below:

Given that VWP process demonstrated reduction in total solids, it could be considered in applications such as waste sterilization, soil fertilization and pellets production for heating purposes.

Also, VWP treatment enhances the release of sugars from waste materials.

Cranfield University Study funded by European Regional Development Authority (a unit of European Union)

The principal conclusion from this study is that municipal solid waste from Vantage Waste Processor can be converted by a two stage process involving hydrolysis and fermentation into ethanol. Furthermore, if the cellulose content of the MSW (municipal solid waste) is reasonably high (70% or greater) then the yield of ethanol generated is in excess of the 300L per tonne target.

Conclusion from University of Coventry study

We are confident from these trials, that with pre-treatment - by removing non-biomass contaminants, the Vantage Waste Processing system will be able to deliver in excess of 300 litres of ethanol per tonne of MSW. It is, therefore, our opinion that, assuming a sugar-to- ethanol conversion of 55%, acid hydrolysis of MSW, pre- treated using the Vantage Waste Processing System, can liberate sufficient sugars for fermentation to produce ethanol in excess of 300 liters per ton of MSW.
