Efforts to shift from petrochemical plastics to renewable and biodegradable plastics have proven tricky — the production process can require toxic chemicals and is expensive, and the mechanical strength and water stability is often insufficient. But researchers have made a breakthrough, using wood byproducts, that shows promise for producing more durable and sustainable bioplastics.
A study published in Nature Sustainability, co-authored by Yuan Yao, assistant professor of industrial ecology and sustainable systems at Yale School of the Environment (YSE), outlines the process of deconstructing the porous matrix of natural wood into a slurry. The researchers say the resulting material shows a high mechanical strength, stability when holding liquids, and UV-light resistance. It can also be recycled or safely biodegraded in the natural environment, and has a lower life-cycle environmental impact when compared with petroleum-based plastics and other biodegradable plastics.

“There are many people who have tried to develop these kinds of polymers in plastic, but the mechanical strands are not good enough to replace the plastics we currently use, which are made mostly from fossil fuels,” says Yao. “We’ve developed a straightforward and simple manufacturing process that generates biomass-based plastics from wood, but also plastic that delivers good mechanical properties as well.”
Injection molder and contract manufacturer Rosti Group has installed the first Roctool heating and cooling system at its facility in China. This will allow the molder to reduce its CO2 emissions by as much as 40%. Rosti said that it sits at the center of the supply chain and has a duty and an opportunity to make a positive environmental impact on the plastics industry. Petrochemicals rPETRecycling CrudeOil
Roctool’s patented technology consists of quickly heating the tool surface by induction and rapidly cooling the tool via water channels. With this technology, Rosti said that it can offer key advantages to its customers, such as aesthetic, design, and process improvements, while meeting commitments to reduce carbon emissions at the plant.
As the macro environment continued to be turbulent, negative-feedback in commodity market has also been given out. For example, front-month contracts of PSF and cotton showed a large fall. Cotton price has fallen dropped below pre-holiday price, while PSF one was in range-bound at the level before CNY. Obviously, the bull market has faded.Petrochemicals rPETRecycling CrudeOil
VSF plants maintained offers at 15,600-16,000yuan/mt, but traders’ sources were much cheaper than that of plants. Some yarn mills who intended to replenish feedstock despite large price spread started to balance the profit and loss—-whether to give up the cooperation with some VSF plants temporarily. Although the viscose market was chaotic, it was controllable. In recent years, the concentration of viscose has gradually increased, and the plants had the flow of goods control capability.
As to rayon yarn, as there were many spinners and traders, whose feedstock cost, pre-sales and inventory of each spinner were different, especially in the big fluctuation, rayon yarn got more chaotic. Vortex-spun rayon yarn was a typical representative. Vortex-spun R30S was offered at 20,000yuan/mt and the traded priced lower 1,000, 2,000 or 3,000yuan/mt were timely rumored which further hit the market trading enthusiasm.
Albert Einstein famously said that ‘We can’t solve problems by using the same kind of thinking we used when we created them.’
That logic, while indisputable, tends nevertheless to be defeated when industry interests are at stake.Petrochemicals rPETRecycling CrudeOil
Which is precisely why, wrote the EU level trade association European Plastics Converters – EuPC – in a recent op-ed published on EurActiv, we need to be very careful in making exceptions to the Single-Use Plastic Directive.
The SUP Directive was adopted with the express purpose of tackling the problem of the waste plastic polluting the world’s oceans. It represents a key action for the achievement of UN Sustainable Development Goal 14, which calls for the conservation and sustainable ‘use of the oceans, seas, and marine resources for sustainable development’.
The plastics industry, wrote EuPC, is committed to achieving the highest environmental standards set at EU level in order to allow a complete transition to a circular economy and to guarantee a high level of environmental protection.
In recent weeks, however, various voices have been heard to question the range of items that should be covered by the SUP Directive. The paper industry, in particular, has raised concerns regarding the inclusion of polymer-coated paper products, such as cups. The limited amount of plastics used in such items, said the paper industry, does not warrant their falling within the scope of the Directive.
Yes, these materials will degrade over time. But how long will it take? And under what environmental conditions?
Over the past 20 years I’ve written much about the efforts of polymer scientists to create a plastic that will “disappear” in the environment. No matter how much money is spent on research, though, the dream of biodegradable polymers has proven elusive.
An article in the business section of the Wall Street Journal on March 20, 2021, by Saabira Chaudhuri (“Plastic Straws That Quickly Biodegrade in the Ocean? Not Quite, Scientists Say”) takes an in-depth look at why biodegradability might not offer the solutions promised. Petrochemicals rPETRecycling CrudeOil
Chaudhuri begins by examining Danimer Scientific’s Nodax, which the company claims degrades within a “few months” in ocean environments and is suitable for backyard composting.
Direct-spun PSF has fallen back since Mar with PSF futures down from 8,500yuan/mt to 7,000yuan/mt, a decrease of 1,500yuan/mt or 17.6%, and spot one down from 8,000yuan/mt to 7,000yuan/mt, a decrease of about 1,000yuan/mt or 12.5%. By now, both PSF futures and spot one have retreated to the level before Spring Festival. Petrochemicals rPETRecycling CrudeOil
But it was not caused by higher inventory or worse downstream acceptance. On the contrary, direct-spun PSF plants were in short supply and downstream plants profited better compared with POY.
There are mainly two reasons behind this wave of quick decline.
After PSF futures declined, direct-spun PSF plants held firm prices due to short supply. Traditional traders partly lowered prices after gaining profits. For spot-futures traders, they were advantageous in price under trades by basis, driving spot PSF market to deteriorate quickly.
Price adjustments attributed to volatility in pricing and availability of raw materials and high freight rates.Petrochemicals rPETRecycling CrudeOil
Effective immediately, or as existing contracts permit, BASF is globally increasing the price of additives for plastic applications, including heat and UV stabilizers, antioxidants, processing aids, lubricants and pigments) by up to 20%. The company attributed the price adjustment primarily to the significant volatility in pricing and availability for essential raw materials and the rapid escalation of of freight rates.
BASF is also increasing prices in North America for its nylons and intermediates. increase prices for polyamide polymer and intermediates. Prices of nylon 6 and caprolactam are being increased by 15¢/lb and copolymer by 18¢/lb.
