21c update - Turning olive pits into energy
By Tania Hershman September 25, 2007

After you've enjoyed a tangy olive, don't throw away the pit - it could soon be providing a clean, green answer to heat and electricity production, thanks to technology developed by Israeli start-up Genova, now setting up its first pilot plant.

The company, which was founded in September 2004, is headquartered in the northern town of Karmiel. The drive takes you up through a lush, verdant landscape, a fitting introduction to Genova's environmental philosophy of "waste not, want not." Biomass - organic waste - is generated as a by-product of many types of industry worldwide, such as forestry, and crop and livestock farming. The biomass is generally transported at great cost to a landfill to rot, or it is burned; both rotting and burning create methane, a greenhouse gas which plays a major role in global warming. However, if harnessed properly, methane can be a very valuable source of energy.

With increasing concern over the supply of fossil fuels for electricity generation, as well as the environmental implications of burning coal and oil, why not do something useful with biomass, thought Dr Yuri Wladislawsky, an engineer and the founder of the company, who emigrated to Israel from Tblisi, Georgia, in 1996.

Wladislawsky decided to focus first on the biomass produced from the olive presses that are a feature of the Middle Eastern landscape, "because olive waste is difficult waste to process because of the pits," explains Yonat Grant, an industrial engineer who is the CEO of the company, which has two other employees as well as Wladislawsky and was set up within the Misgav Technology Center incubator, where it will stay for another year. If the company can succeed with olive waste, she says, then any other biomass will be simple in comparison.

First, the olive waste is heated and dried and then it is introduced into the reactor. Here it undergoes two processes, pyrolysis and gasification, which involve the biomass being heated to 800 degrees centigrade, at which temperature its molecules break down. A combination of high-calorie gases including methane and carbon monoxide are produced which, because they are lighter than air, flow upwards through a pipe into a standard gas turbine to generate electricity in the usual way. The other by-product is coke, which can be turned into the active type of coke that can be sold for use to power air conditioners or as filters for various substances.

Harnessing the power of biomass is not a new industry and there are a number of companies around the world who are attempting to show that biomass can replace some of the fossil fuels we use, but Genova's technology employs a novel technique, which the company prefers not to disclose, for maintaining the high temperatures needed for the process. This technique means that "only ten percent of the electricity we produce is used to power the [olive waste conversion] process," Granot told ISRAEL21c. "The process is 90% efficient. Our competitors are only 50% efficient, at best." Thus, where the cost of a kilowatt/hour is 9 cents for the company's competitors, Genova's cost is only 2 cents per kw/h.

This high efficiency and low cost has attracted much attention, piquing the interest of the Israel Electric company, Israel's sole electricity provider. "Israel Electric is looking for alternative sources of energy, not for economic reasons but for environmental ones, for society," says Granot. Israel Electric has added a $60,000 investment to the NIS 1.4 million (approx $300,000) that the company receives from the government-run Misgav incubator over the two years of its stay. Genova will be relocating to Misgav shortly.

Genova already has a fully-working prototype to prove that the patent-pending concept works, and is now planning its first pilot project, a 200 kw/hour plant in the Druze village of Julis in northern Israel. The plan is that olive waste from Julis' olive oil press will be fed into Genova's reactor and produce enough electricity to power the press, so it will be self-sustaining.

"For 8000 hours, which is one year of production, we need 1600 tons of waste," explains Granot. An olive press usually produces waste which is one-third of the weight of the olive oil produced, so 1600 tonnes of waste would be produced from a press making 4800 tons of olive oil. The press in Julis is a little smaller than this, so some waste will be brought in from other presses.

"The plan is to build [the pilot reactor] for the next olive season, which is September/October 2006," says Granot. Genova is now looking to raise $1.25 million to pay for the pilot project and for marketing and sales of the reactor, which could be on the market in 2007.

There is an interested investor in California, famous for its wine industry and where environmentally friendly electricity production is being encouraged and subsidized, who asked to see if Genova's reactor works with vineyard waste products.

"We tested it with wine waste from the Carmel Mizrachi vineyard, and we proved it works with wine," says Granot. "For the US, we have proved that we can do it for any kind of biomass - wine, corn, sunflowers."

There is also interest coming from Australia, which has a flourishing olive oil industry. Genova, whose focus is on small reactors, not larger than 200 kw/h, with processing of the biomass on site to avoid transport costs, will first target Europe. "There are 2000 olive presses in Spain, for example," says Granot. And then there are Greece, Italy and all the other olive oil-producing countries, where governments are actively encouraging biomass conversion. Genova will sell them a 200 kw/h reactor for around $300,000, which the press will earn back in less than four years.

"It will pay for itself," says Granot.

So the next time you have a martini, hang onto the olives - they could be heating your house.

There are now demand for palm kernel.

I dont know for what but, buyers are looking for it in huge amounts.

I asked the mills, but they say they dont have it as whatever they have were feed to the burners to run the mill.

hmmmm

Palm Kernel Oil: Palm kernel oil is a "tropical" oil derived from the seeds of palm tree fruit. Because this is mainly a saturated oil (80%-85% saturated) and low in essential fatty acids, palm kernel oil may be heated without the risk of creating harmful breakdown products (as is the case with unsaturated oils, when heated). Although palm kernel oil is a saturated oil, some research conducted in areas ripe with live palm trees (where very fresh palm kernel oil is available) indicates that a diet high in tropical oils may decrease cholesterol levels, however other research contradicts these findings. As with other saturated oils, palm kernel oil (especially refined palm kernel oil) should be used in moderation or avoided in one’s diet.

There was a strong pressure group against palm oil, but the more research they conduct the more beneficial they found the plant to be.

Palm Oil save the country's economy many rounds.

It is really a wonder crop.

A Gift from the Sustainer.

For Education and Discussion Only. Not for Commercial Use.

Olive oil is probably best known as something you use for cooking, and it's normally found in the kitchen, but it actually has many other uses that have nothing to do with cooking.

1.
Shaving Cream
Have you ever found yourself without shaving cream? If you happen to have olive oil then you're in luck because it makes a great substitute for shaving cream.
2.
Foot Cream
Our feet often have the tendency to become dry and cracked, especially during the winter months. An easily solution for this problem is olive oil. Rub a little on your feet like lotion and it will soften up those crusty feet.
3.
Hair Conditioner
Hair issues are a big thing, especially for women. No one likes a bad hair day. If you rub a dab of olive oil in dry hair it works as a conditioner. It makes your hair shiny and smooth.
4.
Hairball Solution
This one is particularly important for cat owners. Hairballs are a common problem in cats. Just add a couple teaspoons of olive oil into a can of your cat's food and your furry family members will be hairball free in no time.
5.
Bath Ingredient
Do you have dry skin? Rub a little olive oil onto your skin or add a little to your bath water. You can take a relaxing bath and soothe your dry skin at the same time.
6.
Floor Polish
You can even use olive oil to polish your floors. Just add three parts olive oil to one part white vinegar and get to work. Your floors will be clean and shiny in no time.
7.
Makeup Remover
Commercial makeup removers can be expensive and some of them don't work very well. Olive oil is an inexpensive solution. Use it just like you would use a normal makeup remover. It works great.
8.
Manicure Soak
Are you thinking about giving yourself a manicure? Mix some olive oil with water for a pre-manicure soak. It will soften up your hands and cuticles.
9.
Snoring Solution
Do you keep your spouse up at night with your snoring? Drink a small amount (just a quick sip) of olive oil and it will lubricate your throat and stop the snoring.
10.
Lice Remover
Olive oil is also a great way to get rid of lice. The commercial lice shampoos are expensive and a lot of the time they don't work. Saturating the hair with olive oil will suffocate the little critters.
