‘Great Pacific garbage patch’ is 16 times bigger than we thought, scientists say

Scientists arrived at this figure, which is around 16 times higher than previous estimates, by assessing aerial images alongside data from ships dragging nets through the region.

Occupying the waters between California and Hawaii, the patch is the largest of five major offshore waste accumulation zones that result from converging ocean currents.

The research was conducted by scientists at the Ocean Cleanup Foundation, who are attempting to understand the true extent of plastic pollution in the world’s oceans.

“Overall you would expect plastic pollution is getting worse in the oceans because we are producing and using more plastics, globally and annually,” Dr Laurent Lebreton told The Independent.

The Problem of Plastic Waste will require Drastic Measures

Plastic waste is everywhere, but several countries, from Malawi to Morocco, have made plans to phase out plastic shopping bags and other disposable items. Now, following in their footsteps, Great Britain is planning to enact new measures aimed at weaning customers off disposable plastic products that are chucked out after a single use, thereby greatly adding to the already massive amounts of plastic waste.

Among other measures, the European nation will impose a 5 pence (RM0.3) surcharge on single-use plastic bags and lean on retailers to set up plastic-free aisles. The aim, according to Prime Minister Theresa May, is to eradicate all plastic waste within the next 25 years.

So far so good. But here is a problem: that quarter-century timeline is unfeasible. There is way too much plastic waste in the world as it is, and such long-term plans will do little to alleviate the situation in the near future.

Responsible consumption, a guide to a zero-waste New Year

It’s early in the new year and there is no other way to hit the ground running than an inspiring new year compliments and ambitious felicitation, may the new year bring fulfillment to set goals and aspirations.

New year resolution is a tradition in which an individual resolve to change an undesired trait or behavior, to accomplish a certain personal goal or otherwise improve their lives.

Recycling Must Be Included in the Infrastructure Bill

As Congress and the Trump administration contemplate a $1 trillion investment in infrastructure, the question of how to utilize those dollars looms large. If the focus is just asphalt and concrete, it will miss the heart of American manufacturing. At the top of manufacturers’ needs is access to good, consistent, high-quality feedstocks to make into new products. Let’s help meet that need with some of the best possible domestic sources of raw materials: the paper, plastics, glass, metals and packaging discarded by U.S. homes and businesses. That means including funding for improved recycling in the infrastructure bill as a way to ensure long-term reliable supply created right here at home.

GREEK YOGURT WASTE COULD BE USED IN JET FUEL AND LIVESTOCK FEED

Your Greek yogurt creates food waste that could one day be used in jet fuel.

That’s right—when Greek yogurt is made, it leaves behind liquid whey, which is the watery remains after protein is strained from milk. A process that mixes this waste with thousands of species of bacteria and some heat transforms the whey into a new material called bio-oil, which could be used in biofuels or additives in livestock feed.

and

Waste streams can be renewable feedstocks to produce biofuels and chemicals. Acid whey is an example waste stream and is produced by the Greek-yogurt industry in large volumes. This whey and other waste streams have been successfully converted into methane gas by anaerobic digesters with open cultures of microbial consortia (microbiomes). However, the revenue from methane has been relatively low. Until now, no other products could be produced with microbiomes from this waste stream. This has now changed. Here, we showed that acid whey was converted into valuable medium-chain carboxylic acids (MCCAs), such as n-caproic acid (n-hexanoic acid) and n-caprylic acid (n-octanoic acid), without addition of external electron acceptors.
