Oil is our old problem. The solution is change our consumer behaviours,
start to use renewable energies and new technologies as fuel cell. Last
but not least waste recycling is really important as alternative to the
raw materials.

Interesting point, time for some number crunching. Gasoline has
45Mj/kg, plastic has about 30Mj/kg, in terms of energy saved in
converting bauxite aluminum is proable worth as much as gasoline, and
paper is worth about 15Mj/kg. Rough estimate of 30Mj/kg of recycled
stuff, assuming 50% of that energy is lost in recycling and conversion
that give us a hydrocarbon payback of about 15Mj/kg of recycled stuff.


At 15Mj/kg, assuming that the truck gets 5mpg, that means that in an
average 5mile stretch you would need to pick up 3kg of stuff. Pretty
easy from my experience.

Even if the houses are 60Meters apart and only 10% of them recycle, and
if we assume that only 25% of the energy is reclaimable each recyling
house would only have to average 0.5kg of stuff each week.

Seem like a good deal to me.

I save up a lot and bring to recycle center.
There I see people come in with a SUV and a little bag or 2 or tins or
plastic. They drive 1/2 mile minimum out of way to do this.
Waste of Gas i think.

Can plastics recycling can get a boost; through general use of plastics
only curbside recycling bins?

What about the inclusion of scrap-tire rubber? A growing number of
projects in North America are yielding scrap rubber e.g., road pavement
additives, crumb-rubber, tire-mulch, and a variety of other products.

Something as basic as cutting the sidewalls off of tires can avoid
cutting through the thread's steel-belts; hence avoiding damaging
wear on expensive cutting-knives; and making tire recycling even more
practical. Scraped tires have greatly reduced bulk, and can be readily
processed, stored and transported economically.

Recycling tires was how it was first discovered
that recycling is a regulatory energy hog that
is second only to automobile manufacturing
as an energy hog and roadside killer.

So buring them is still the way to go for everybody
except the US.

Can plastics and tire recycling initiatives spur environmental cleanup
agendas?

Here in California, the agency "California Integrated Waste
Management Board" demonstrates rare examples of successful "public
private partnerships." California has enacted laws on computer and
electronic waste recycling; whose recycling plants have generated
interest worldwide. The plastics and glass from recycling operations
are mixed into concrete for road pavements, and crumb-rubber is also
being applied to asphalt for road pavement.

Yet, plenty of scrap plastics, and rubber are exported to Asia; where
infrastructures there allows for wide utilization of scrap materials.

How much scrap can actually go towards energy from waste objectives;
esp. with the current prices for oil?

Oil is distilled from plastics and tires at this company in China.

Japan also does-well with "waste to energy" initiatives; as they
have long lived-with limited energy resources.

Separate the glass, metal, and use the mass as fuel in a continuos
cycle. see EathFirst Tech. EFTI.OB as one example. Someday THEY will
by your curb-side waste. (g)
