Much of the researchers&China easy peel lidding film39; current focus is on the potential use of various biodegradable - and otherwise environmentally conscious - materials they might use as fillers to further strengthen the mix.Toughness, which was improved, is different from strength, explained study co-author Katrina Cornish. Tomato skins are under consideration, as are eggshells."Imagine trying to pull a block of concrete apart with your hands. But karate chopping it with your hand or foot is testing its toughness - how easily it breaks. Thattesting its strength.While other attempts at making this type of rubber-enhanced bio-plastic have reduced # the strength of the PHBV by as much as 80 per cent, only 30 per cent of the strength was lost in this study - a much more manageable amount.

Zhao said.Beyond packaged foods; a bio-plastic could potentially be used in other food-related applications such as utensils and cutting boards."We want something that would otherwise go to waste that is sustainable and also relatively cheap," Vodovotz said.The research team reported success with a rubber-toughened product derived from microbial fermentation that they said could perform like conventional plastic.A biodegradable replacement for petroleum-based plastics has been marred by various challenges; however, new research has found a way that could yield earth-friendly plastics.

They're even looking at the potential to attack two environmental problems at once, by seeing how invasive grasses that environmentalists are yanking out of waterways might play with the rubber-infused mix. You can never pull it apart, but if you're strong enough you can break it," Cornish said.A biodegradable replacement for petroleum-based products has to meet all sorts of standards and, so far, attempts at viable replacements from renewable sources have faced limited success due to processing and economic constraints.Increased flexibility, without a significant loss of strength, is particularly important when it comes to plastic films commonly used to package everything from fresh produce to frozen foods, she said.

The end product was 75 per cent tougher and 100 per cent more flexible than PHBV on its own - meaning it is far easier to shape into food packaging."We could dry them, grind them up and potentially use these grasses as fibrous filler," Vodovotz said.The new study involved melting rubber into a plant-based thermoplastic called PHBV along with organic peroxide and another additive called trimethylolpropane triacrylate (TMPTA). end-of Tags: plastic, bio-plastic, environment.The study published in the 'Journal Polymers' has shown that combining natural rubber with bio-plastic in a novel way results in a much stronger replacement for plastic, one that is already capturing the interest of companies looking to shrink their environmental footprints.Other research teams have combined rubber and PHBV, but the products have been too weak to withstand all the demands of a food package - from processing to shipping, to handling in stores and homes, especially containers that are used for freezing and then microwaving, said the studysenior author, Yael Vodovotz."Previous attempts at this combination were unsuccessful because the softness of the rubber meant the product lost a lot of strength in the process," said lead author Xiaoying Zhao.They've discussed using the 'cake' left behind after a fellow researcher extracts oil from spent coffee grounds.This new study highlights the greatest success in this area so far, according to scientists. Among the obstacles, products to date have been too brittle for food packaging

Washington: People worldwide could be ingesting five grammes of microscopic plastic particles every week, equivalent in weight to a credit card, researchers said Wednesday."This is likely to have much more serious health effects than a rather small number of plastic particles in food and water," Grant said. Gaps in data were filled with assumptions and extrapolations that could be challenged, though the estimates, they insisted, were on the conservative side." In the last two decades, the world has produced as much plastic as during the rest of history and the industry is set to grow by four per cent a year until 2025, according to a new report by Grand View Research.

A third of that – some 100 million tonnes – is dumped or leaches into Nature, polluting land, rivers and the sea. high barrier films Manufacturers end-of Tags: zero plastics, plastic pollution, water pollution.They invited other researchers to build on their conclusions.More than 75 per cent of all plastics wind up as waste.Some experts remain sceptical about longterm impacts. Coming mostly from the tap and especially bottled water, nearly invisible bits of polymer were also found in shellfish, beer and salt, scientists and the University of Newcastle in Australia reported.Plastic particles have recently been found inside fish in the deepest recesses of the ocean and blanketing the most pristine snows in the Pyrenees mountains between France and Spain. "Developing a method of transforming counts of microplastic particles into masses will help determine the potential toxicological risks for humans," said co-author Thava Palanisami, a microplastics expert at the University of Newcastle.The authors of Wednesdayreport were up front about the limitations of their research, starting with the fact that little is known about health consequences. The WWF said only hard targets backed by binding national commitments could hope to stem the plastics tide. "Based on the evidence that is currently available, I do not think that health effects of microplastics are a major concern," Alastair Grant, a professor of ecology at the University of East Anglia told AFP. But waste must be folded back into a circular economy, and plastics should no longer be made from fossil fuels, Lindebjerg added.

"We need a new, legally binding agreement to combat marine plastic pollution – it should be a stand-alone treaty like the Montreal Protocol or the Paris Agreement."If we don't want it in our bodies, we need to stop the millions of tons of plastic that continue leaking into Nature every year.""Zero plastics" does mean no plastics used. "What we do need is political and economic actions to reduce the amounts of plastic being disposed of into the environment and encourage recycling.But that doesn't mean plastics isn't a major problem, he added."The global goal must be to reduce plastic leakage into nature to zero," Eirik Lindebjerg, WWFglobal plastics policy manager, told AFP.

"Media and watchdog reports have recently uncovered numerous cases of plastic waste from rich countries destined for recycling in poorer ones being dumped or burned instead. On current trends, the ocean will contain one metric tonne of plastic for every three metric tonnes of fish by 2025, according to The New Plastics Economy report, published by the Ellen MacArthur Foundation."Not only are plastics polluting our oceans and waterways and killing marine life, but italso in all of us," said Marco Lambertini, director general of WWF International, which commissioned the new report.The findings, drawn from 52 peer-reviewed studies, are the first to estimate the sheer weight of plastics consumed by individual humans: about 250 grammes, or half-a-pound, over the course of a year.Another study calculated that the average American eats and drinks in about 45,000 plastics particles smaller than 130 microns annually while breathing in roughly the same number

The fabric that the NGO develops was recently voted the most sustainable fabric at an Ashoka Conference. This technology equips them to grow their own food with much غير مجاز مي باشدt-efficiency,” she says. We realised that people in the slums, mostly ragpickers, didn’t have anything.“I think the consumers should start being more aware of where the products they buy come from and how sustainable they have been produced.” said the 27-year-old. The NGO focuses on upcycling, energy efficiency and food security, while trying to provide employment to ragpickers.So far, the organisation has upcycled about 10,000 tonnes of waste out of which 6,000 tonnes was plastic waste and trained more than 500 ragpickers through various skill development workshops. “We have just started a project in food security that promotes agriculture through hydrophonics which means to grow food without needing soil.”

The revenue generated goes back to the NGO to sustain its activities, explained Kanika. The aim is to generate as much employment as possible while efficiently managing waste even in the remotest of villages around Delhi since the artisans in those villages are ones who help weave it with a technology they know best, charkha. But till that happens, to make sure that things don’t get too bad for residents of Delhi, the newly appointed Director of Conserve India, Kanika Ahuja, is trying to do her best to upcycle the city’s waste as much as possible in an organisation that was started by her parents in 1998.The goal shouldn’t be to just protect the environment but to improve the world such that the environment no longer needs protection.

A recent product line uses old clothing which is shredded and then re-weaved into cloth using natural fibers. end-of Tags: ngo, kanika ahuja, environmental pollution.Since most plastic waste instead of getting recycled ends up in landfills, Conserve India took it upon itself to help “develop this technique where the plastic from the landfill sites could be reinvented into a new material we call Handmade Recycled Plastic. During ourwork at the slums we saw that the food there was scarce and China easy peel lidding film vegetable vendors who came to sell there more often than not exploited the slum dwellers. “When we started working in waste management, we started working with the slum community. We use it to develop fashion products which are sold internationally since we don’t have a strong market in India yet.Lack of employment and environmental pollution through waste are two major issues the city battles. Because only when the consumers become aware will the bigger brands take notice of it which will help improve conditions for both, the environment and the workers,” says the social entrepreneur. Also, even all the waste they collected was plastic and nothing can be done about it because the normal processing methods don’t usually work on plastic. The only resource available to them was waste which was not generating enough of an income for them
