Biosensors are showing great promise as tools
for detecting levels of contaminants in soil and water. This report
looks at what a biosensor is, current research and provides contact
details for several researchers in the field
Over the past five years the U.S. military
has developed a Site Characterization and Analysis Penetrometer
System (SCAPS), which allows rapid on-site assessment of levels
of several key pollutants. This allows cost-effective remediation
of contaminated soils by providing detailed knowledge about the
level and extent of contamination at each site.
Generating electricity from the oceans has
been widely discussed for 40 years. Time and again attempts have
been made to harness the both wave and tidal power, usually with
little success. However, with advances in engineering in the past
few years, the oceans have become an economically feasible source

Although sustainable construction is a term
often used, what does it actually mean? This report looks at a working
definition considered by the CIB.
Article on the development of bioenergy as
a renewable resource, looking at benefits and potential in both
the developed and developing world.
Fifteen years ago, the Finnish town of Vaasa
ran out of landfill space. The citizens were faced with either finding
a large new site to dump the towns refuse, or fundamentally
changing the way they handled the waste they produced. Choosing
the latter option, the town now sends just 9.5% of its waste to
a new, small landfill site the rest is reused, recycled,
or turned to energy.
The Ecological Village is a concept which
is becoming increasingly popular in Sweden. This report looks at
one such village, and how it has minimized the environmental impact
of new housing in a forested area near Stockholm.
A report which examines some European advances
in sustainable wastewater treatment. The report shows the reasons
that current technology will not result in sustainable systems,
and examines the radical rethinking and new technology needed.
Constructed wetlands are increasingly beign
viewed as an environmentally friendly and energy efficient way to
treat domestic and municipal wastewater. Wetlands are effective
at reducing biochemical and chemical oxygen demand, and removing
up to 90% of nitrates and phosphates. This report examines the state
of their implementation and looks at some new technology.
Fujita doesn't just write about innovative new techologies; we develop them at our R&D center in Atsugi city.
