Scientists’ research helps to safeguard greenbelt and promote affordable housing

30.04.2003


The number of housing developments on greenfield sites could be significantly reduced thanks to technology, pioneered by University of Greenwich environmental scientists, which can quickly decontaminate polluted and brownfield land, ready for building affordable environmentally friendly housing.



nown as Accelerated Carbonation Technology (ACT), this new process can treat contaminated land and hazardous waste in minutes rather than the days or weeks required by some conventional methods.

It works by adding a granular binder to contaminated soil and pumping carbon dioxide into the mixture. The three components rapidly combine to produce a type of cement that is very stable and can trap heavy metal that can originate from industrial activities. The land can then rapidly be used for housing or other developments, reducing overall costs and the need to build on greenfield sites.


“A by-product of the process is the potential to recycle large quantities of the greenhouse gas, carbon dioxide, rather than release it into the atmosphere, making this technology even more attractive,” explain its developers, Dr Colin Hills and Dr Paula Carey of the university’s Centre for Contaminated Land Remediation.

“In 1999, we approached Blue Circle Industries (now Lafarge UK) to invite them to collaborate on the ACT project,” explains Dr Colin Hills. “They subsequently funded a successful trial, which has led to a three year project to develop the technology for the UK market.”

An industrial consortium has been formed to bring ACT to the market, and the process is now commercially available.

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

So-called pre-distorted states accelerate photochemical reactions too

What enables electrons to be transferred swiftly, for example during photosynthesis? An interdisciplinary team of researchers has worked out the details of how...

Im Focus: The first precise measurement of a single molecule's effective charge

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...

Im Focus: Room-temperature multiferroic thin films and their properties

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.

Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
