PLA - The Answer?What’s the Question?

• Petroleum packaging vs. corn packaging - what's the big deal?The difference between petroleum-based packaging and corn-basedpackaging is like night and day.... Simply stated, NatureWorks ™PLA corn packaging is both compostable and recyclable. Initialtesting has demonstrated that a BIOTA PLA bottle made from corndegrades in 75-80 days in a commercial compost situation.Petroleum based PET bottles will not compost.. Corn packagingprovides an annually renewable, nature-based alternative totraditional non-renewable, fossil fuel, petroleum-based plasticmaterials. NatureWork ™PLA uses 30% to 50% less fossil fuel toproduce than petroleum-based plastics. Because they are madefrom corn, PLA bottles burn clean and do not release harmfulchemicals into the atmosphere. Everyone wants to make adifference...now you can.

• From the Biota water site.

PLA - The Answer?

• Only compostable in municipal facilities.

• Does not return nutrients to the soil

• Recyclable, but by who?

• Contaminates the only developed waste streamwe have for plastics. PET

• Uses less oil? Debtable

• Rising price of tortillas in Mexico

• Food for water bottles?

• GMO’s

The 1st PLA-Bottle-Conference

PLA (Polylactide), a compostable plasticmade from renewable resources such as corn, is a highly topical subject right now, especiallyin the light of increasing crude oil prices.

The stretch blow moulded PLA bottles used by Biota or Natural Iowa

(USA), Belu (UK), Vitamore (Germany) and +1Water (Canada), as wellas reports in the trade press, have aroused significant interest from thePET and beverage industry.

Would you like to find out more about the possibilities, limitations

and future prospects of PLA for bottle applications?

Castro was rightApr 4th 2007

From The Economist print editionAs a green fuel, ethanol is a good idea,

but the sort that America produces is bad

It is not often that this newspaper finds itself in agreement with FidelCastro, Cuba's tottering Communist dictator. But when he roused himself

from his sickbed last week to write an article criticizing George Bush'sunhealthy enthusiasm for ethanol, he had a point. Along with other criticsof America's ethanol drive, Mr. Castro warned against the “sinister idea ofconverting food into fuel”. America's use of corn (maize) to make ethanol

biofuel, which can then be blended with petrol to reduce the country'sdependence on foreign oil, has already driven up the price of corn. As

more land is used to grow corn rather than other food crops, such as soy,their prices also rise. And since corn is used as animal feed, the price ofmeat goes up, too. The food supply, in other words, is being diverted to

feed America's hungry cars.

Should California banincandescent light bulbs?

• CFL lamps can save $$ and CO2emissions

• Florescent bulbs are cool running

• Everyone else is doing it.

• Can you mandate good behavior?

Stob’s Theory

• It’s a new appliance.

• It converts your waste to useful energy

• You install it in your house

• Inputs are all your waste

• Outputs are heat(hvac & water) &electricity

• Reduces or avoids need for other inputssuch as gas and electricity.

Consider

• 50% of electricity produced is lost to linelosses.

• Coal fired plants are still being installed inTexas and the South

• 4.6 pounds per person per day of garbagegenerated.

• 70% could be recycled

Consider the Pellet Stove

• Bixby's first generation stove, the 55,000 BTUMaxFire, burns corn, wood or biomass pellets at99.7 percent combustion efficiency, meaning itgives off little ash. It holds 106 pounds of cornand heats a 3,000-square-foot area at about 45percent the cost of heating oil and 55 percentthe cost of natural gas.

• Bixby engineers have designed a biomassfurnace that will provide heat, hot water andeventually electricity.
