Scientists accidentally create mutant enzyme that eats plastic bottles
Scientists have created a mutant enzyme that breaks down plastic drinks bottles – by accident. The breakthrough could help solve the global plastic pollution crisis by enabling for the first time the full recycling of bottles.

The new research was spurred by the discovery in 2016 of the first bacterium that had naturally evolved to eat plastic, at a waste dump in Japan. Scientists have now revealed the detailed structure of the crucial enzyme produced by the bug. The international team then tweaked the enzyme to see how it had evolved, but tests showed they had inadvertently made the molecule even better at breaking down the PET (polyethylene terephthalate) plastic used for soft drink bottles. “What actually turned out was we improved the enzyme, which was a bit of a shock,” said Prof John McGeehan, at the University of Portsmouth, UK, who led the research. “It’s great and a real finding.”

Make Your Own 3-D Printer Filament From Old Milk Jugs
Creating your own 3-D printer filament from old used milk jugs is exponentially cheaper, and uses considerably less energy, than buying new filament, according to new research from Michigan Technological University. [...] The savings are really quite impressive — 99 cents on the dollar, in addition to the reduced use of energy. Interestingly (but again not surprisingly), the amount of energy used to ‘recycle’ the old milk jugs yourself is considerably less than that used in recycling such jugs conventionally.

ReCreate Ireland - Creativity through Reuse
Great idea.
For creative groups, we aim to offer easy access to a rich and varied selection of textures, colours and shapes. Members are also be able to participate in creativity workshops facilitated by fully trained professional artists either in-house or on your own premises. We intend to be the first choice of teachers, early childhood educators and arts animators in the community.

For businesses, ReCreate reduces the costs of moving on end-of-line materials. We are a professional, credible and reliable partner organisation and our aim is to divert approximately 115 metric tonnes of clean materials from landfill annually. All collections are free of charge.

Hogan describes bin charge increases as ‘opportunistic’ - Environmental News | The Irish Times
LOL Greyhound.
Greyhound Recycling last month announced increases of 50 cents a month for customers on a flat monthly charge, 50 cents for each black bin collection for customers who pay by the lift and two cents a kilo for customers who pay by weight only. In a letter to customers, it described the levy as “tax imposed by the Government of Ireland on the people of Ireland”. However, following a complaint to the [National Consumer Agency] that the by-weight increase was 76 per cent more than the [government landfill levy] increase, Greyhound reduced the charge to an additional one cent a kilo.
