Africa Biofuel and Emission Reduction Company is focussed on bringing a triple-bottom-line biofuel business model to Africa.
Africa Biofuels set out to find a biofuel process that did not compete for a food or use agricultural land. It looked for a product that could actually enhance the environment and benefit the people of the area.
It identified Croton megalocarpus, an indigenous tree, as its focus.
There is detailed discussion of the project under the explanatory and news section of the website that promotes its arguments in detail.
In a quick scan and search I was unable to identify how the byproducts (oil cake and glycerine) are to be used and what income they will generate. This “income” and the cost of manual collection from wild trees are critical to the viability of the process. In fact I not find any costing or economics on the site but am taking that up via email.

In an interview with green2tech

Jeff Broin of ethanol producer Poet said the following
8). In the great debate over how much corn ethanol is affecting food prices, what do you think about some newer reports that have said biofuels have affected food prices significantly?
Every study depends on the assumptions of its author, and the opponents of renewable fuels have been able to generate a few that say what they want. Almost every independent study I’ve seen has said that ethanol production has had a very small impact on the consumer’s price for food, especially in comparison to the impact of rising energy prices.
A study from the Agricultural and Food Policy Center at Texas A&M said, “The underlying force driving changes in the agricultural industry, along with the economy as a whole, is overall higher energy costs, evidenced by $100 per barrel oil.” Just do the math. A semi can haul 4,200 boxes of corn flakes at a time, and with 10 ounces of corn in each box, that’s a total of 46.9 bushels of corn. At a $6 bushel, the corn in all 4,200 boxes has a value of $281.40. To haul those boxes 1,500 miles, however, would cost $881.25 with diesel priced at $4.70 per gallon. That means it takes 21 cents of diesel per box to get it to the store, yet the value of corn in that box is less than seven cents. What do you think is the real driver of higher food prices?
But this study surely has nothing to say about biofuels not pushing up the price of food? In fact what would the fuel cost have been if the truck was run on biodiesel?
Its also flawed in that the calculation is for $100 crude & $ 4.70 / gallon diesel – even at $50 crude and the corresponding diesel price of $ 2.86 / gallon (extrapolated from GasBuddy data) the diesel cost is still 13 cents. This is a of food retail and consumer demands not fuel costs!

Lets not even start calculating the packaging cost and the wholesale and retail margins!
