BEER giant Carlsberg will next year launch a “greener” alternative to glass bottles made from wood fibres.  The Danish brewer has developed a prototype “green fibre” bottle as a biodegradeable alternative. Glass bottles have to be recycled in the UK or washed for re-use up to 25 times in other markets. But as the process uses energy and water, a viable alternative is set to become hugely significant. Carlsberg is also ditching plastic ring multi-can holders which trap animals and clog up the oceans. …Spokeswoman Myriam Shingleton said: “We are thinking of a completely new packaging for bottles, which is a green fibre bottle that will be made from a controlled wood source, so a bio-base.”
