venture formed to mine landfills for energy creation
Advanced Plasma Power (APP), a UK-based waste-to-energy
company and Group Machiels, a global waste management firm, announced
a major joint venture in order to undertake the first enhanced
landfill mining project in the world – involving an investment
of hundreds of millions of Euros.
The Closing the Circle concept, an enhanced landfill mining concept,
has been developed by Group Machiels in collaboration with a
consortium of academic partners (KULeuven, VITO, UHasselt), extracting
the maximum value from historic waste streams as materials and
energy, as well as CO2 sequestration or offsetting.
The Closing the Circle concept is being implemented in the project
at the landfill site of Remo Milieubeheer NV in Houthalen-Hechteren,
Belgium, a subsidiary of Group Machiels. More than 16 million
tons of waste are stored at that landfill site. The type, amount
and location of the waste stored is well documented, allowing
its effective and efficient mining. Around 45 percent of the
stored waste can be recycled as material. The recycling residue
can be processed through APP’s patented Gasplasma technology,
Europe’s first sustainable waste-to-energy application of this
The joint venture aims to construct an energy plant using up
to five Gasplasma units, with a net electrical power of 75 to
100 MW. The energy produced by the Gasplasma units will be fed
into the national electricity grid in Flanders.
The Gasplasma process is a gasification and plasma conversion
technology that converts the waste stream into a clean hydrogen-rich
syngas and a vitrified recyclate product called Plasmarok that
can be used as a building material or replacement aggregate.
The Gasplasma process destroys harmful gases leaving the high
quality syngas to be used to generate clean, renewable, local
The Gasplasma process is suited for the Closing the Circle project,
which will see the Remo landfill site that has been in use since
the 1970s, returned to its original state with green spaces to
be enjoyed by the community.
