Uptake of tire wear additives by vegetables grown for human consumption

Chemical residues from tyre wear detected in leafy vegetables for the first time

06-Jun-2024 - Car tires contain hundreds of chemical additives that can leach out of them. This is how they end up in crops and subsequently in the food chain. Researchers at the Center for Microbiology and Environmental Systems Science at the University of Vienna and the Hebrew University of Jerusalem have ...

Turning plastic waste into a valuable soil additive

New method creates useful char from plastic and corn waste

13-Jan-2023 - University of California, Riverside, scientists have moved a step closer to finding a use for the hundreds of millions of tons of plastic waste produced every year that often winds up clogging streams and rivers and polluting our oceans. In a recent study, Kandis Leslie Abdul-Aziz, a UCR ...

Catalyst to make renewable paints, coatings, and diapers discovered

Groundbreaking discovery will enable the manufacturing of biorenewable materials from trees and corn: A Startup wants to make it possible

11-Jan-2023 - A team led by University of Minnesota Twin Cities researchers has invented a groundbreaking new catalyst technology that converts renewable materials like trees and corn to the key chemicals, acrylic acid, and acrylates used in paints, coatings, and superabsorbent polymers. The new catalyst ...

From the road to the plate: lettuce takes up toxic additives from tyre wear

Chemicals from tyre wear could get into our vegetables via sewage sludge and waste water

05-Jan-2023 - Wind, sewage sludge, and waste water carry tyre wear particles from roads onto farmland. A new lab study shows: The pollutants contained in the particles could get into the vegetables grown there. Researchers at the Centre for Microbiology and Environmental Systems Science (CMESS) at the ...

Throwing tomatoes at bacteria

Strides in the usage of discarded tomato peel to develop antimicrobial mixtures

20-Oct-2022 - In recent years, agro-industrial residues have been explored for the development of bioplastics, food supplements, and other applications. In Europe, nearly 10 million tons of tomato fruit were processed in 2020, generating half a million tons of tomato pomace (residues of peels, stems and ...

Maize and milk proteins can replace fossil fuels and metals in the production of nanostructured surfaces

Sustainably produced nanotechnology

28-Jan-2022 - New research results from Linnaeus University opens for a future with more sustainably produced nanotechnology, where limited natural resources can be replaced with, among other things, maize and milk proteins. Nanotechnology can be found almost everywhere in our daily lives, although it is ...

Spinach: good for popeye and the planet

Chemistry experiments show potential to power fuel cells

07-Oct-2020 - "Eat your spinach," is a common refrain from many people's childhoods. Spinach, the hearty, green vegetable chock full of nutrients, doesn't just provide energy in humans. It also has potential to help power fuel cells, according to a new paper by researchers in AU's Department of Chemistry. ...

Less drain on freshwater supplies with seawater fuel discovery

22-Aug-2018 - Researchers have found that seawater can replace freshwater to produce the sustainable fuel Bioethanol, reducing the need to drain precious resources. The study was carried out by researchers at the University of Nottingham. Their results showed that seawater can be used in Bioethanol production ...

How biofuels from plant fibers could combat global warming

28-Feb-2018 - Scientists, companies and government agencies are hard at work on decreasing greenhouse gas emissions that cause climate change. In recent years, biofuels produced from corn have emerged as a fuel source to power motor vehicles and, perhaps, airplanes. But corn is problematic as a biofuel source ...

Paints and varnishes based on potato starch

Metal coating based on renewable raw materials

03-Jan-2018 - If a surface has to be protected against corrosion, in 80 percent of all cases this takes place through coating it with paints or varnishes. When doing so, the proportion of bio-based, environmentally-friendly solutions is extremely small. Researchers at the Fraunhofer Institute for Applied ...
