Waste as a national resource – maybe it should not all be used for biofuels

We have had the company of a clean energy consultant, Jenya Khvatsky, over the past couple of months. Jenya was asked to flesh out our sketch of available waste across the UK (see related blog post) using official data.

The report can be viewed Waste Utilisation in the UK. Its conclusions are that the UK disposes of around 59m tonnes of household, commercial and agricultural waste each year, after recycling or composting some 40m tonnes (total therefore being 99m tonnes). This compares with our earlier estimate of 110m tonnes.

It should be stressed that Jenya’s figure of 59m tonnes is the officially recorded amount of waste. Actual amounts produced are certainly higher than this simply because not all waste finds its way either into recycling or into landfill. The ‘true’ figure may be 30% or even 40% higher than this.

Scope for home grown bio-fuels from waste

Many companies are already able to produce a litre of ethanol from waste at a lower cost than producing a litre of petrol from crude oil. As waste is practically a ‘free’ feedstock, the impetus to turn waste into fuel will only grow as the price of crude oil rises.

Visit to TMO

On Wednesday we visited TMO Renewables (www.tmo-group.com) in Guildford. TMO is a second generation bio-fuel producer that is beginning to gain commercial traction in both the USA and China. The first generation of bio-fuel operations received a great deal of (mostly warranted) criticism for food displacement effects and in most cases relied heavily on government subsidy to support business models.

TMO

By virtue of years of R&D on its proprietary bacteria, TMO has come up with a highly efficient process whose main characteristics are:

  • Ability to use multiple feed-stocks
  • Consumes complex sugar chains without a problem
  • Requires much lower inputs of expensive enzymes.
