The process depends on co-pyrolysis — a controlled heating process — of the spent coffee grounds and PET plastic waste, conducted at an eco-friendly temperature of 600°C. Potassium hydroxide serves as ...

In Malaysia, one of the world’s top producers of palm oil, millions of tons of oil palm ash (OPA) are left behind as ...

A Korean research team has developed water treatment adsorbent that can selectively remove water-soluble micromolecules. It is also cheap, easily synthesized and renewable. Professor Cafer T. Yavuz ...

A simple, compact system first collects moisture from the air (left) and then releases the trapped liquid (right) when heated, which results in potable water. Clean, safe water is a limited resource ...

A research team successfully developed a solar-powered artificial plant device and rapidly purified soil contaminated with ...

Water pollution is one of the most pervasive problems afflicting people. Therefore, seeking highly efficient, low-cost methods to decontaminate water is very much in demand. In this paper, ...

The removal and recovery of chromium(III) (${\rm Cr}^{3+}$) from aqueous solutions with a spheroidal cellulose adsorbent containing the carboxyl anionic group was investigated. The adsorption of ${\rm ...

Clean, safe water is a limited resource and access to it depends on local bodies of water. But even dry regions have some water vapor in the air. To harvest small amounts of humidity, researchers ...
