World's first bioplastic vinyl record launched in the UK
Paris (AFP) July 20, 2022

A British firm says it has produced the world's first bioplastic vinyl record, which it hopes will reduce the need for highly toxic PVC.

Bioplastics are derived from sources such as sugars and starches -- rather than oil or gas -- and do not create any toxic waste in their production.

The new bioplastic vinyl by UK firm Evolution has been endorsed by NGO Music Declares Emergency, a climate change campaign group set up in 2019 by artists and music industry professionals.

"If Evolution can deliver an alternative guilt-free vinyl, it could get rid of one of the key polluting elements of the music industry completely," the NGO's co-founder Lewis Jamieson told AFP.

Currently, all vinyl records are made from Polyvinyl chloride, or PVC -- described by Greenpeace as "the most environmentally damaging plastic", whose production releases toxic, chlorine-based chemicals that are "building up in the water, air and food chain".

The issue has come to the fore thanks to the recent boom in vinyl sales -- which surpassed $1 billion last year in the United States alone (a first since the mid-1980s).

Few anticipated the vinyl revival that began in the mid-2000s, so record companies found themselves scrambling to secure PVC -- often relying on foreign firms with poor safety records.

Kyle Devine, who wrote a book on the environmental impact of the music industry, "Decomposed", said the PVC for 90 percent of US vinyls in 2015 came from a Thai company that was "pouring pollution into the Bangkok river".

"PVC is an especially nasty plastic to make. It's a difficult one to dispose of, to recycle or decompose," he told AFP.

He added that it would be wrong to see the current dominance of streaming and digital music as an answer to the industry's climate impact.

"Digital data still takes up space and uses energy. In fact, given the current size and spread of the music industry, it's likely more environmentally-taxing than ever before," Devine said.

Evolution released the first 20 records made with the bioplastic via a prize draw -- a compilation of young artists including electro duo Bicep and US singer Angel Olsen.

It has taken almost five years of testing due to delays caused by the Covid pandemic, but the firm says they are close to matching regular records.

"It presses the same as PVC," said co-founder Marc Carey. "The final piece of the puzzle is there is a little bit of surface noise when you play the record so we are working on that. We think we are two weeks away from finalising the recipe."

Music Declares Emergency is clear that changing the production of vinyl records will do little for the bigger picture on climate change, but Jamieson said such innovations were symbolically important.

"It reminds people that thinking sustainability doesn't mean you have to live in a mud hut and have no fun," he said.

Advances in the design and manufacturing of novel freeform optics
Huddersfield UK (SPX) Jul 15, 2022
Freeform optics bring precision optical systems into a new ear, delivering superior imaging in compact packages, or functions otherwise impossible. Surfaces that are axially unbalanced or have no axis of rotational invariance are known as freeform surfaces. Advanced freeform optical designs supplementary to ultra-precision manufacturing and metrology techniques have upgraded the lifestyle, thinking, and observing power of existing humans. Imaginations related to space explorations, portability, accessib ... read more
