UASB Inventor to be Awarded
Tyler Environmental Prize
 Los
Angeles, CA -- Gatze Lettinga, a Dutch scientist known for
his invention of anaerobic wastewater treatment and his
determination to make it universally available, will receive
the 2007 Tyler Prize for Environmental Achievement.
The Tyler Prize executive
committee and the international environmental community will
honor Lettinga at a ceremony at the Four Seasons Hotel in
Beverly Hills on Friday, April 20 at 7 p.m. The award
consists of a $200,000 cash prize and a gold medal.
On Thursday, April 19, at 2 p.m.,
Lettinga will give a public lecture at the Davidson
Conference Center of the University of Southern California,
which administers the prize.
Lettinga's technology, known as
Upflow Anaerobic Sludge Blanket (UASB), stands behind three
quarters of the world's anaerobic systems for treating
industrial and residential wastewater.
By design, the core technology is
freely available. Lettinga chose not to patent his
invention. "The UASB-reactor concept is still
completely open for everyone, consequently particularly also
for the citizens in developing countries, and that is what I
wanted and still want," Lettinga stated recently.
Jules van Lier, one of Lettinga's
successors at Wageningen University, wrote in a nomination
letter: "Professor Lettinga can be characterized as a modest
and honest man giving highest priority to the quality of
life of the billions of poor people on this planet who are
deprived of clean drinking water and sanitation."
Compared to energy-intensive
traditional processes, anaerobic treatment actually produces
energy in the form of methane gas, which can be reused as
fuel. In addition, the method yields much less residue than
traditional wastewater treatment, while processing 10 to 20
times as much waste.
If sewage and organic refuse in
the Los Angeles basin were processed anaerobically (at
present only some biosolids receive anaerobic treatment) and
all methane captured for reuse, the savings in carbon
dioxide emissions would amount to taking 200,000 to 400,000
cars off the road, according to van Lier.
Lettinga said that anaerobic
treatment "is becoming the method of choice for the
treatment of practically any type of wastewater. We foresee
that in due course the same will happen for sewage
treatment."
Once Lettinga perfected the UASB
design in 1972, it took him just four years to develop the
first industrial system, for the Dutch sugar beet industry.
"We then proceeded to expand the
application of the system to a great variety of industrial
effluents, including quite complex and even toxic
wastewaters," he said.
The group focused most of its
efforts on countries unable to afford centralized sewage
processing or industrial wastewater treatment.
Thousands of anaerobic wastewater plants are now operating
worldwide, according to van Lier and Stanford University's
Perry McCarty, a pioneer of research into anaerobic
processes. McCarty's work provided the theoretical
foundation for the UASB.
McCarty praised Lettinga for
developing local expertise to support and advance anaerobic
processing.
"Instead of causing the usual
brain drain where the best scholars from developed countries
are drawn away to the more developed countries, Dr.
Lettinga's approach achieved education of scholars, but in a
most useful way, they returned to their countries to apply
an appropriate and environmentally sound technology,"
McCarty wrote.
The industrialized world,
particularly North America, has been slower to adopt the
technology for sewage treatment.
"In spite of the evident
feasibility and huge socio-economic advantages … great
obstacles were put in our way," Lettinga said, "Over the
years this reluctant attitude has fortunately slowly
diminished."
The Tyler Prize citation
recognizes Lettinga for "your research and development of an
environmentally sound novel process for the treatment of
polluted wastewater and its implementation worldwide,
especially in developing countries."
The Tyler Prize for Environmental
Achievement is one of the premier awards for environmental
science, energy and medicine. It was established by
the late John and Alice Tyler in 1973 and is awarded
annually to individuals associated with world-class
environmental accomplishments.

New
Thames Tunnel Sewage Interceptor
 London,
England -- An unprecedented project to clean up London’s River
Thames has been announced - the biggest project of its kind ever
undertaken in this country. A 30km tunnel will intercept sewage
and rain water discharges along the length of the river and
transport the waste water for treatment in east London.
London’s current sewer network, which
was built by Joseph Bazalgette in the second half of the
nineteenth century, was hailed as a major engineering
achievement in its day, and collects sewage and rainwater
run-off together.
Today, with the climate changing and
the city expanding, the system is under pressure and 52 million
cubic metres of untreated sewage and rainwater pollute the
Rivers Thames and Lee each year - enough to fill the Albert Hall
about 525 times. Of this, 32 million cubic metres comes from
sewer network overflows, which provide the only safety valve to
prevent the overloaded system from backing up and flooding homes
and streets.
The discharges kill fish, create a
higher health hazard for users of the river and damage the
aesthetic appeal of the Thames.
Environment minister Ian Pearson
said, "I think most Londoners would be shocked to hear that,
because of an historic but increasingly outdated sewer network,
a huge amount of untreated sewage and rainwater is spilling into
the Thames at least once week. This is unacceptable. This tunnel
is the right solution for London and for the environment. It
will give us a twenty-first century River Thames that we can all
be proud of."
Today’s announcement follows six
years of detailed work by a range of specialists. In particular,
the reports by the Thames Tideway Strategic Study, the
independent review by consultants Jacobs Babtie, and the reports
recently completed by Thames Water have been instrumental in
helping determine the solution. All recommended a major tunnel
under the Thames.
The project is expected to be
delivered by 2019/20. The cost has been estimated at least Ј2bn.
The economic regulator Ofwat will be tasked with ensuring that
it is delivered cost effectively. It is estimated that it will
add around Ј37 to Thames Water sewerage bills by 2017.
