About Biodegradability

Here’s a good study regarding biodegradability and sustainable packaging solutions. This study from Inhabitat by Starre Vartan is about biodegradability of takeout-boxes, mostly regarding time taken. The box is followed till 19 days, by when it is almost unrecognisable.

Because I’ve heard mixed messages about the compostability of packaging labelled biodegradable, I figured the only way to figure out what works and what doesn’t is to stop listening to rumors and try them out myself. My first experiment was with a Whole Foods deli container, simply because it was at hand; I shop at the supermarket in both Manhattan and in Darien, CT where the chain has recently opened its newest store.

Here, the study is regarding the gate-grave part of the product; But what about cradle-grave journey, where these are made from natural resources (I don’t think these are recycled; not food grades)… No sustainable solution yet, I think.

Laser Cut Wooden Lamps : CNC Hedonism

Found at the Boing Boing Bazaar:

WHY ????

It says:

“Curious Customs’ laser cut wooden lamps are attractive and inexpensive. They would fit right in a Pasadena Arts & Crafts bungalow, but they would improve the decor of a gas station lavatory, too.”

Is CNC killing craftmanship and also humbleness with it?

Composites in Renault’s Wind convertible

Sheet moulding compound (SMC) composites are used for the one-piece lightweight collapsible hardtop roof on Renault’s new Wind convertible, slashing the weight of the folding hard top system by more than half compared with earlier designs. The “rotating” SMC roof, which is made by Webasto-Edscha, weighs just 21.8kg complete with its kinematic mechanical components. This is little more than one quarter of the weight of the convertible roof of the Renault Mégane convertible, which tips the scales at more than 100kg.

Bugatti Veyron gets a Polycarbonate Roof

 

The new Bugatti Veyron 16.4 Grand Sport combines the looks of an open-top roadster with the dynamics and safety of a closed vehicle. This is made possible by a targa top incorporating a transparent panoramic roof, which can be removed in a few simple steps to switch to open-top driving. “To make the roof easy to handle and also reduce its weight significantly, we opted to use Makrolon® in our design. This polycarbonate from Bayer MaterialScience is an established material for the series production of lightweight automotive glazing. We were also keen to benefit from the Leverkusen company’s know-how, which covers all process steps in the manufacture of polycarbonate glazing,” explains Daniel Starmann, glazing project manager in Bugatti’s exterior engineering department.

Boeing 787 Dreamliner Launched

After so many delays and modifications, the revolutionary Boeing 787 Dreamliner, the first ever aircraft to be made of 50% carbon fibre composite material, make its international debut on 18th July at the Farnborough Airshow. 

  

An increased use of carbon fibre composite materials over traditional aluminium has significantly reduced the weight of the aircraft and there is a reported 20% saving in fuel with no compromise on speed. As well as this, the carbon fibre composite fuselage requires far fewer parts compared with aluminium as there is less to bolt together. A one piece composite fuselage section saves a total 1,500 aluminium sheets and 40,000 aluminium fasteners. The composite fuselage also means more humidity can be allowed in the cabin’s air. In aluminium aircrafts the cabin air is kept dry to lessen the risk of corrosion. The 787′s windows are also far larger than those in other aircraft.
