Biomass is material which
originates from living or previously living plant or animal
matter tha can be converted in to fibres. Wood, such as forest
residues, yard trimmings, wood chips and municipal solid waste
are the most prolific form of biomass, but there are others
including: chicken litter, sugarcane residue, bamboo, corn,
hemp, some grasses, vegetables and a variety of tree species.
Some of these materials are grown on an industrial scale for
use as biofuels as a replacement for fossil fuels. Materials
can be left to rot and the resulting methane gas used as fuel
and others can be fermented to produce ethanol or bio diesel.
However wood remains the largest biomass energy source and
is burned to produce heat and energy.
Wood grades A, B and C smaller than 50mm are suitable for
biomass. Grade A consists of pallets, untreated wood offcuts
and packaging crates. Grade B is mixed demolition timber,
furniture and painted timber. Grade C is chipboard, MDF and
contaminated waste wood. Storage and transportation of this
type of loose material can be difficult and expensive. Large
storage areas or silos need to be constructed and for commercial
and industrial bulk loaders will be required, which is uneconomical.
For these materials baling is the ideal answer, providing
the baling press can supply sufficient compaction to hold
the smaller wood chips/dust together. Bales must also be sufficiently
dense and of a suitable size to maximise weight and transportation.
A typical biomass baling operation would use a baling press
such as a Macpresse Mac 110/1 capable of producing 26 to 30
tonnes of baled biomass per hour. This fully automatic, continuous
press uses a single 92 Kw motor and pump generating 170 tonnes
of ram thrust. It and a cycle time of only 15 second and a
highly efficient cutting and tying system, the low energy
usage makes the Mac 110/1 one of the most economical baling
presses on the market. Lined with bolt on Hardox plates for
wear resistance and capable of using either steel or plastic
tying wire it suited to baling a range of materials including
With such a press the loose infeed would be around 200Kg per
cubic metre and the output 750Kg per cubic metre. At this
density the bale will be stable and ideal for incineration.
Burnable plastic wire is needed to secure the bale as is wrapping
in a plastic film enabling the material to be delivered by
any form of transport: ship, container or tautliner vehicle,
only incurring delivery costs minimising transportation costs.
Biomass fuel has an advantage over refuse derived fuel from
municipal solid waste in as much as Grade A fuel can be sold
while RDF requires the producer to pay a gate fee to the incinerator
owner, although this fee is considerably lower than the landfill
tax charge. Biomass is a clean, renewable, sustainable energy
source produced from abundant supplies of raw material. New
developments are making biofuels, bioproducts and biopower
more readily available. Modern biomass boilers are highly
efficient, although expensive to install the savings year
on year will recover the outlay and carbon emissions will
only be a fraction of those or coal or electricity. So keen
is the government to encourage the use of renewable energy
that the domestic Renewable Heat Incentive, was launched in
April 2014 and provides financial support to the owner of
the renewable heating system for seven years. The scheme covers
England, Wales and Scotland.
