Covestro: First ever order of PU resin for wind blades delivered

Covestro announced that it has delivered its first commercial order of polyurethane raw materials for wind blades to China. According to the World Wind Energy Association, China is the world’s largest wind power market with 221 GW of installed capacity at the end of 2018.

The blades, produced by Zhuzhou Times New Material Technology (TMT), one of the largest manufacturers of wind blades in China, have then been delivered to the wind turbine technology company Envision. They are scheduled to be installed in a wind farm in East China in July 2019.

Covestro delivered polyurethane resin to TMT for the production of 18 polyurethane wind blades of 59.5-meter-length, also for the spar caps and shear webs. These blades were delivered to Envision, heralding the successful deployment of Covestro’s polyurethane resin in blades for commercial wind farm projects. To ensure successful deployment, the Covestro wind power team produced a prototype of the wind blades which has passed static and fatigue tests. The prototype was put into trial operation at a wind farm in central China in 2018.

Ulrich Liman, Global Head of R&D, Business Unit Polyurethanes at Covestro said, “We are very excited to be working with Envision and TMT on this first sales order of PU wind blades in China. Polyurethane resin in the production of wind blades, is a game-changing innovation delivered by Covestro teams around the world. We remain committed to our vision of creating products that benefit society and improve people’s lives all over the world.”

Zilu Liang, Deputy Chief Engineer, Wind Power Products at TMT, said, “As an innovative material, polyurethane, compared to epoxy resin, has advantages in costs and in the production process. We have cooperated with Covestro since 2016, and now we have achieved continuous production. We hope to further collaborate with Covestro to explore large-scale wind blades and wind blades completely made of polyurethane.”

According to Covestro, the polyurethane infusion resin was developed to help the wind power industry meet the growing demand for longer wind blade designs. Wind turbine rotor blades of this kind are typically made out of fibreglass-reinforced resin by applying vacuum infusion technology. The successful use of polyurethane resin for manufacturing large-scale rotor blades for wind turbines suggests that the material itself features superior mechanical properties and anti-fatigue performance. There are also benefits for the production processes in the wind blade factory, for example, a faster curing process and better processing properties to deliver higher productivity levels.

Irene Li, Head of PU Application Development Asia Pacific at Covestro, summarised, “This is the first step to realising the industrialisation of polyurethane resin in the wind industry, opening up a new chapter in polyurethane chemistry. We believe that our polyurethane solution delivers significant advantages in wind blade production and along the value chain.”

The driver shortage in the trucking industry is a problem that every trucking company, large and small, has to deal with. There are many reasons that this shortage has come about, but the newest trend to affect the industry is the acceptance by states of marijuana use. Legalization of recreational marijuana by states is making it even harder for the trucking industry to find drug- free drivers.(1) Trucking companies have safety guidelines to meet and the possibility of having impaired drivers will not help them do so.

Safety is something the trucking industry takes very seriously, not just for the drivers, but for everyone on the roads. There are precautions that need to be taken and guidelines that need to be followed to ensure the safety of all people. Legalization of marijuana greatly affects these precautions, because it affects the user’s reaction time among other things. A tractor trailer can do much more damage in an accident than a standard car due to the size difference. The possibility of truck drivers being under the influence is that much more serious. “We simply cannot have that in the industry…You cannot have people that are using controlled substances, that are impaired, operating 80,000 pound equipment or tanks full of chemicals or petrol,” American Trucking Associations President and CEO Chris Spear said. “It is a problem that the states, we don’t believe, are taking into consideration.”(1)

The reason this affects the driver shortage is because drug tests are required for drivers and now more carriers are willing to take the next step and do a hair test as well, even though it is not required at this point. This means potential drivers who are using marijuana, even if legally, are either walking out the door or failing the drug screenings. Peter A. DeFazio, the House Transportation Chairman, said he too is concerned with the safety risks associated with marijuana in the trucking industry and that Congress needs to advance research into a system for real-time testing.(1)

On the other hand, if the states legalized marijuana, why does a trucking company have the right to refuse employment to a driver, even if they are not intoxicated while driving, only using it on the weekends? How would that be determined by a drug test? There is no true way to tell how or when the drug is used. The industry needs to know if the driver is currently under the influence. If the state legalized it, then it is accepted regardless of what the trucking industry says. “You don’t want someone driving a semi or a private vehicle who meets some sort of intoxication standard,” DeFazio said. “But to totally disqualify someone from employment because in a state that has legalized it, they used it on a weekend when they weren’t working is very problematic.”(1)

Road Scholar Transport only hires the most professional and experienced drivers. Our drivers are subject to background checks and safety checks well beyond the industry’s standard. We have implemented a drug and alcohol testing program. We require a drug test for every new hire, 50% of our drivers are randomly drug tested each year, and also if there is an accident where vehicles are towed or if it results in an injury. Road Scholar Transport continues to have no controlled substances or alcohol violations in out CSA score.

Legalization of Marijuana Affecting Driver Shortage

200 Years Of Rapid Global Population Growth Will Come To An End

Authored by Max Roser via OurWorldInData.org,

One of the big lessons from the demographic history of countries is that population explosions are temporary. For many countries the demographic transition has already ended, and as the global fertility rate has now halved we know that the world as a whole is approaching the end of rapid population growth.

The visualization below presents this big overview of the global demographic transition – with the very latest data from the UN Population Division just published.

As we explore at the beginning of the entry on population growth, the global population grew only very slowly up to 1700 – only 0.04% per year. In the many millennia up to that point in history very high mortality of children counteracted high fertility. The world was in the first stage of the demographic transition.

Once health improved and mortality declined things changed quickly. Particularly over the course of the 20th century: Over the last 100 years global population more than quadrupled. As we see in the chart, the rise of the global population got steeper and steeper and you have just lived through the steepest increase of that curve. This also means that your existence is a tiny part of the reason why that curve is so steep.

The 7-fold increase of the world population over the course of two centuries amplified humanity’s impact on the natural environment. To provide space, food, and resources for a large world population in a way that is sustainable into the distant future is without question one of the large, serious challenges for our generation. We should not make the mistake of underestimating the task ahead of us. Yes, I expect new generations to contribute, but for now it is upon us to provide for them. Population growth is still fast: Every year 140 million are born and 58 million die – the difference is the number of people that we add to the world population in a year: 82 million.

Where do we go from here?

In red you see the annual population growth rate (that is, the percentage change in population per year) of the global population. It peaked around half a century ago. Peak population growth was reached in 1968 with an annual growth of 2.1%. Since then the increase of the world population has slowed and today grows by just over 1% per year. This slowdown of population growth was not only predictable, but predicted. Just as expected by demographers (here), the world as a whole is experiencing the closing of a massive demographic transition.

This chart also shows how the United Nations envision the slow ending of the global demographic transition. As population growth continues to decline, the curve representing the world population is getting less and less steep. By the end of the century – when global population growth will have fallen to 0.1% according to the UN’s projection – the world will be very close to the end of the demographic transition. It is hard to know the population dynamics beyond 2100; it will depend upon the fertility rate and as we discuss in our entry on fertility rates here fertility is first falling with development – and then rising with development. The question will be whether it will rise above an average 2 children per woman.

The world enters the last phase of the demographic transition and this means we will not repeat the past. The global population has quadrupled over the course of the 20th century, but it will not double anymore over the course of this century.

The world population will reach a size, which compared to humanity’s history, will be extraordinary; if the UN projections are accurate (they have a good track record), the world population will have increased more than 10-fold over the span of 250 years.

We are on the way to a new balance. The big global demographic transition that the world entered more than two centuries ago is then coming to an end: This new equilibrium is different from the one in the past when it was the very high mortality that kept population growth in check. In the new balance it will be low fertility keeps population changes small.
