Default Mazda turns old bumpers into new ones

Quote:
Hiroshima, Japan – Mazda has successfully recycled old bumpers into new ones, becoming the world’s first automaker to do so, the company said. Scrapped bumpers from end-of-life vehicles (ELVs) will be used to make rear bumpers for the Mazda Biante, a minivan sold in Japan.

Conventionally, bumpers from ELVs are shredded and incinerated to produce heat energy. They make up a large proportion of the plastic used in vehicles and Mazda said it is proactively developing recycling technologies as an effective way to increase its material recycling ratio. The company became an industry leader in bumper recycling when it began processing damaged bumpers collected from vehicles still in use through its dealer network in Japan, and aims to further develop and adapt it for recycling ELV bumpers.

The process has previously been technically and economically different, since many ELVs are over ten years old and the composition of their bumpers’ polypropylene plastic and adhesive properties of the paint vary considerably. Unwanted materials such as metal attachments must also be removed before recycling. To overcome this, Mazda began designing easily-recyclable bumpers in the 1990s, and has also developed and implemented efficient ELV bumper collection and processing methods in collaboration with companies in Hiroshima. As a result of these initiatives, the cost of recycling is less than the cost of purchasing new plastic, the company said.
Initially, Mazda will collect bumpers from end-of-life Mazda vehicles in the Hiroshima area. The recycled plastic will comprise approximately ten per cent of each new bumper produced.

Makes me wonder if the emissions are sent right into the atmosphere. Inhaling fumes from burning plastic is a major no no .

Indeed. It doesn't help when the company was founded by braindead ppl. What's next Mazda telling the public to mix ammonia and bleach than take a big wiff? SMH yet ppl will continue to buy because they like the smiley faces on the cars.

Plastic pyrolysis usually takes place in a vacuum (no oxygen) and produces methane, hydrogen, and some crap called "char." It's good for fuel generation along with heat production for heating buildings and stuff.

In this case, I'd presume that since they're only melting the plastic, it's no worse than the process used to create new bumpers daily, except now they're cutting out the first half of the lifecycle.

I wonder how much this adds to their manufacturing process. How much is this costing them?

I think it follows the same idea as burning garbage for power... if you burn it hot enough, it's clean.

2011 Mazda huh? YOU MAD BRO?! I'll type in little words for you. Mazda burn plastic, no good, bad for air, air you breath. I have some crayons I can draw you a picture let me know.

It seems like alot of work to go through in the name of recycling. Doesn't incineration require alot more resources? Seems like they might be losing money especially since only 10% makes it into newer parts.

They are recycling the plastic so it's not burned anymore. Thats the whole purpose of the article.
