I'm not so sure about that. Aluminium production is very energy intensive and uses a lot of chemicals. The second generation of bioplastics can be produced in a very environmentally friendly process and many types are even biodegradable.
Not necessarily true:
Aluminum is currently the best material for mass production in products, especially tech due to e-waste. Bauxite being the most common aluminium ore. Refinement uses much less energy to produce, and is improving with recent advancements, especially compared to the Hall-Héoult Process (the major industrial process aluminum extraction). Aluminum is theoretically 100% recyclable without any loss of its natural qualities and requires only 5% of the energy used to produce aluminium from ore, though a significant part (up to 15% of the input material) is lost as dross (ash-like oxide). Recycled aluminium is known as secondary aluminium, but maintains the same physical properties as primary aluminium. Secondary aluminium is produced in a wide range of formats and is employed in 80% of alloy injections. The process produces aluminium billets, together with a highly complex waste material, which can be reused as a filler in asphalt and concrete.
Every year, Americans throw away enough paper and plastic cups, forks, and spoons to circle the equator 300 times (
http://www.cleanair.org/Waste/wasteFacts.html). Plastic produces more waste from recycling and general consumer discard. Recycling produces more pollutants, including chemical stews when breaking down different products.
Recycling is not cost-efficient and annually results in a net loss. It costs $50-60 to landfill a ton versus $150+/- to recycle.
Only the recycling of aluminum really makes any money. Reclaiming metals is feasible and fairly easy, whereas plastics and paper are expensive, wasteful and overly difficult. The biggest disadvantage to recycling is that it gives the consuming public a false sense of 'security'; a sense that they're doing something to benefit the environment. recycling can be bad for the environment. In fact, except for materials like metal and some glass, recycling is almost always bad for the environment. One of the best places to start is with a report from Perc.org, called the
Eight Great Myths of Recycling. "One argument made for recycling notes that we live on a finite planet. With a growing population, we must, it seems, run out of resources."
E-waste is a major issue, especially with plastics. There are 2 plastic islands the size of Texas, one in the
Pacific Ocean - the "Great Pacific garbage patch"and one in the
Indian Ocean and more being discovered almost monthly.
The patch is characterized by exceptionally high concentrations of pelagic plastics, chemical sludge and other debris that have been trapped by the currents of the North Pacific Gyre. Despite its size and density, the patch is not visible from satellite photography, since it consists primarily of suspended particulates in the upper water column. Since plastics break down to even smaller polymers, concentrations of submerged particles are not visible from space, nor do they appear as a continuous debris field.
Newly Discovered 'Plastic Island' Shows Global Epidemic Worsening
Charles Moore - TED discussion on plastic - 7 minutes but alarming facts on plastic toxicity and huge annual increases in waste.
As Japan has serious garbage issues, a Japanese scientist invented a machine that breaks any plastic down into oil! I've mentioned the on MacRumors before as it is an issue the tech industry needs to take into serious consideration. This device is no larger than a microwave and uses less energy than a coffee maker. Read and watch the short 5 min video, if for nothing else than the tech as it's amazing. Hoping quick mainstream adoption lowers the $10k price tag quickly enough for residential use and can make up for its price by reusing the oil. Used in large industrial recycling centers would be amazing!
Plastic to oil fantastic
While everyone is celebrating a new plastic device, my concern is the waste this will produce when thousands then millions more upgrade every year.
If you got this far, thank you. Collectively we can make a difference in plastic usage by "voting with our dollars". We don't need more waste; plastic in tech produces much more waste (and chemical waste from wires, displays, etc) than other naturally occurring metals and smelting. It's great Apple is trying to produce a lower cost iPhone, however plastic shouldn't be much cheaper than smelting aluminum, especially as Apple has dedicated plants for product shells using green energy.
