This 150 page manual with 13 pages of reference, will surely give you all you need to know about the utilisation of cactus pear. You can then build your business by integrating this information with you knowledge of your community using you entrepreneurial skills.
A quick scan through the chapters of the manual illustrates the breadth and detail of the information.
The manual is available for free download, however, if you have problems please email me and I will make sure you get a copy.
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.
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.
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.

You will have noticed I’ve been posting a bit more of non food processing bits and a bit slower in the last while – but remember you can access the information in many ways.

The ongoing disagreement about whether biofuels were effecting food availability, which 2nd generation biofuels offered most, whether wind farms polluted, if nuclear was a better option etc have become somewhat less significant.
Now the economy is the unarguable brake on the development and implementation of alternate energies.
The economic downturn has forced the price of oil down which ends all investors and investees scrambling to the spreadsheet. It has further reduced the availability of capital in those cases where the venture capitalist is still interested in investing. The billions of dollars, euros etc of capital pumped into the banks to keep them afloat will inevitably lead to less money to be invested in subsidising alternate energy and probably more worrying into R&D.
The alternate energy movement runs the risk of faltering and again loosing momentum as it did after the fuel crisis in the 1980s.
I have started writing posts for and environment focussed blog called EcoWorldly.
EcoWorldly brings you news on sustainable successes and ecological failures in other countries that offer lessons for green progress in America. Find perspectives and news on the environmental movement from around the world.
I will be putting links to these posts along with the total text here – otherwise you could visit the site or subscribe in your newsreader.
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.
On the biodiesel project they have been publicising with the Central Energy Fund for some years now they stated that “there is not a very certain government framework at this point in time, which makes finalising a decision not very easy” even though the crude price is multiples of what it was in the beginning!
A recent article highlighted the discontent of commercial maize growers with the South African Governments decision to only allow the production of ethanol from excess maize.
These two stories reinforce what was obvious at the time the Biofuels Strategy was being actively developed – no one was going to be able to make a profitable business out of it without significant subsidisation from government.
The concern is that South Africa can now move away from first generation biofuels, but Africa seems to be getting deeper involved although the constrains are obvious.
The article below by the US Department of Agriculture at the end of 2007 has a good overview, but concludes that maybe there is still room for government to adjust its position. This has apparently not happened to date.

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!
