Video: Ghanaians turn waste into art

By Lisa McDonald / March 31, 2021

Some countries that are significant importers of global waste do not have strong waste management infrastructures, which makes handling the waste difficult. In the absence of government programs, entrepreneurs have started their own initiatives to aid local communities in managing waste. Learn about two individuals in Ghana combating e-waste and glass waste, respectively.

Reinforcing waste-based concrete: Plastic fibers improve mechanical properties of cement–glass composite

By Lisa McDonald / February 16, 2021

Substituting waste materials for cement in concrete helps lower the concrete industry’s carbon emissions and keeps waste materials out of landfills. However, large amounts of glass cullet in concrete will decrease the concrete’s mechanical properties. Researchers in Poland investigated reinforcing the cement–glass composite using plastic fibers.

Video: Clay tiles help restore coral reefs

By Lisa McDonald / December 16, 2020

Coral reefs are experiencing massive die-offs because of bleaching, ocean acidification, and pollution, among other factors. Coral restoration is a top priority for marine researchers, and a team of marine scientists and architects at the University of Hong Kong is exploring using 3D printing to fabricate structurally complex clay tiles for coral to grow on.

Repurpose waste concrete through additive manufacturing

By Lisa McDonald / December 1, 2020

To date, recycling of building rubble into new construction products is limited because the material does not meet strict building regulations. A new £6 million project led by Manchester Metropolitan University and partners across Europe aims to overcome this limitation using additive manufacturing because products produced this way are not subject to the same building restrictions.
