What Do We Do With E-waste? Flash Joule Heating Presents a Solution

What Do We Do With E-waste? Flash Joule Heating Presents a Solution

With Apple rolling out a new iPhone every year and planned obsolescence encouraging consumers to buy and throw out more and more electronics, electronic waste is piling up in landfills globally. An article published in October this year proposes flash Joule heating as a potential solution to the millions of tons of e-waste produced every year.

With Apple rolling out a new iPhone every year and planned obsolescence encouraging consumers to buy and throw out more and more electronics, electronic waste is piling up in landfills globally. Over 40 million tons of e-waste are produced annually, making it the fastest growing category of solid waste globally. E-waste often includes heavy toxic metals that can leach into the surrounding environment, contaminating soil, water, and food sources. Workers who dispose of e-waste have been found to have higher lead content in their blood because of exposure to dangerous dust and smoke when working with the waste and in...
Emerging Solutions to Microplastic Pollution

Emerging Solutions to Microplastic Pollution

While the problem of microplastic pollution still looms large, scientists are developing technologies to remove existing microplastics, prevent new plastics from reaching waterways, and even avoid harmful microplastic manufacturing with the development of bio-based plastics. New, innovative technologies involving microorganisms may also be on the horizon.

From heavy metals to hydrocarbons and oil to plastic debris, marine pollution is a world-wide problem. According to a review by H.S. Auta et al. published in 2017 by Environment International, plastic composes 80-85% of marine litter, and on our current trajectory, the amount of plastic litter in water bodies will only increase. Microplastics don’t decompose easily, and with increasing production and few effective clean-up methods currently implemented on a broad scale, we’re likely to see more and more microplastics in our environment. Microplastics are...
New Anti-Biofouling Technology “SLIPS” into Action

New Anti-Biofouling Technology “SLIPS” into Action

Biofilm buildup on marine infrastructure forces ships to use more fuel and pay for more maintenance, and most solutions are harsh and dangerous for the environment. As a more environmentally-friendly solution, chemists are currently looking into SLIPSs.

Biofouling is a process that occurs when microorganisms, such as bacteria, form communities and adhere to surfaces. These communities are called biofilms, and once established, they often spread rapidly and expand onto other surfaces. Biofouling can create many problems for the environment and man-made structures as it interferes with and accelerates the degradation of infrastructure, such as plumbing and shipping. For example, marine biofouling occurs when biofilm on a ship accumulates, followed by other surface marine organisms, like algae and barnacles, causing ships to use...
