How metals are being used for cheap: An
from CBC News article A new study has found that metals are increasingly being used as cheap plastic and paper, and a new study suggests that metals used in those materials are not as scarce as previously thought.
A new paper in the journal Science estimates that metal-containing plastics are now used in a billion homes in Canada, more than one-fifth of which are home furnaces.
The paper also suggests that the amount of metal in these products is likely to be rising in coming decades.
Metal in plastic and other household products is used for the manufacture of toys, household cleaning products, home appliances, and other items.
While the material used to make those products is not rare, it is the high price that worries scientists and consumers.
“The way that metals can be used in household items, we’re not used to,” said lead author and professor of chemistry and molecular biology at the University of California, San Diego, in a news release.
“We are really concerned about how this is happening.”
The research, which included researchers from the University at Buffalo and the University, Oxford, also suggested that the availability of low-cost plastic is a key driver of the rising use of metals in household products.
“As more and more products are produced using low-quality materials, the availability and cost of materials for production are increasing,” said study co-author John Bresnahan, a professor of chemical engineering and of chemical and biomolecular engineering at the university.
“In a world where we’re using more plastic, this will have a big impact on our environment.”
The study analyzed data on about 200 products from a wide variety of industries, from the auto industry to health care.
The researchers examined what metals were used in the products, the quantities of each material and the potential health impact of their use.
In the auto and healthcare industries, plastics are used for automotive parts, carpets and other materials.
The plastics used in auto parts are often made from plastics such as polyvinyl chloride (PVC), polyvinylene and polyethylene terephthalate (PET).
In healthcare, polyvinylethanene styrene (PVST) and polystyrene are used in dental implants, surgical instruments, and dental crowns.
Bresnaahan said the findings are a wake-up call for the industry, noting that the manufacturing of plastic materials has become increasingly complex, resulting in a wide array of materials that are no longer interchangeable.
“Our findings underscore the importance of using a diverse range of metals and their use in the future for more flexible and energy-efficient materials for new consumer electronics and other applications,” Bresnehan said.
The report found that the industry has begun to make use of more non-toxic alternatives to plastic and that the use of alternative materials is a good way to address the challenges of recycling, and the impacts on the environment.
The metals in the study, which is the first of its kind, have also become cheaper, making them more affordable than the materials used in their manufacture.
The study’s authors said they were confident that the results would help inform future research on metals and other alternatives to plastics.
The findings will help manufacturers to better understand the sustainability of materials used to manufacture their products, which could have important implications for the future of plastics and other products, said lead researcher James McPherson, a senior scientist at the American Chemistry Council, a nonprofit that advocates for the use and reuse of chemicals.
“It’s going to be very important to get a better understanding of the environmental impacts of these materials and how they’re being used,” McPhearson said.
“Metal-containing materials are going to continue to be important in the energy economy and as we move towards a more sustainable world, it will be even more important that they are used to increase the availability.”
