Solving Factory Waste Through Extraction of Valuable Chemicals

At first sight it seems like a good idea to add value to waste strems in the food processing industry.

However, as the project leader says this is not rocket science. The composition of waste streams is generally well known and the technology to extract valuable components already established.It's naive to think companies are paying to dispose of waste streams that contain valuable chemicals which they could be easily extracting and selling.

Many waste streams are actually sold for other purposes such as animal feed and compost while many are already the source of high value chemicals such as essential oils and nutritional supplements. Waste streams have also been used for centuries to produce alternate energy.

Manufacturing companies focus strongly on waste and are just as capable of investigating such opportunities as are researchers.The issue is the financial viability of any particular process and the potential to set up all the players in the supply chain to ensure its sustainable operation.

Cellulosic Ethanol . this year (para 2), this decade (para 3) or longer?

10 Biofuels Predictions for 2010: #9, Cellulosic ethanol “happens”

In 2010, look for:

In the US, ZeaChem’s semi works will , nearing completion at POET’s 25 Mgy project in Iowa, and the opening of Range Fuels’ 20 Mgy facility in Soperton, Georgia.  Internationally, look for LanzaTech’s 500,000 gallon project to open, he first cellulosic ethanol deal in China, and announcements that Brazilian, Vietnamese and Australian sugarcane bagasse will be utilized in advanced biofuels projects. Overall, 102 million gallons of advanced biofuels capacity by the end of the year, with 25 Mgy of it cellulosic ethanol at 17 facilities.

The hint from 2009:

The old saying is that “cellulosic ethanol is always and forever five years away.” If that’s true, then it’s time to party like its 2014, because commercial-scale cellulosic ethanol is just now upon us.

Companies that have been in the R&D phases for years — if not decades — are emerging with a set of technologies, and partners with strong balance sheets, that have every chance of making the 2010s the “Decade of Cellulose”.

In many ways, with solar and energy storage technologies still in the R&D or small commercial phase — biomass represents that “shovel-ready”, “fire when ready” technology for short-term reductions in fossil fuel intensity.

Across the desert to Timbuktu in a car fuelled by chocolate

The Independent reported on two “environmental activists”Andy Pag and John Grimshaw who were setting out to drive from Dorset to Timbuktu in a car powered by chocolate waste.

They left their home town of Poole, Dorset, on a cross-Channel ferry yesterday. They are travelling in a Ford Iveco Cargo lorry powered by fuel which began life as chocolate, in an attempt to raise awareness of “green” biofuels. Their 4,500-mile (7,250 km) trip across the Sahara desert to Timbuktu in Mali should take about three weeks.The pair have taken with them a small processing unit to convert waste oil products into fuel, which they will then donate to an African charity, along with the lorry. They are taking 2,000 litres (454 gallons) of biodiesel made from 4,000kg (8,818lb) of chocolate misshapes – equivalent to 80,000 chocolate bars.

But they will not be able to dip into their tank if they feel peckish because biodiesel does not look or smell like ordinary chocolate. It is made from cocoa butter extracted from the waste chocolate.

The BBC showed a picture of the cargo lorry they are traveling in

Chocolate Powered Lorry to Timbuktu

It is interesting that this comes at a time of discussion in Africa about first generation biofuels and their role in Africa.

Its my own feeling that we have been discussing too long and have been left behind by the developments in Europe & USA, which are now revealing the problems. We should rather be focusing on second generation biofuels which don’t run the risk of taking food from the poor and use waste like this initiative.
