WITECH Biomass Block Press BP 18
FUNCTION OF THE BIOMASS BLOCK PRESS BP 18
 To produce alternative energy made from biomass, such as
sugar cane waste, by densification process and formation of
blocks sized 40 x 40 x 70 cm3.
 The densification process uses mechanical or impact method
that can cut biomass into short pieces and then shape the
material into blocks of the same sizes.
USABLE BIOMASS FEED-STOCKS
 Sugar cane leaves and tops (Javanese: daduk).
 Rice hays, corn waste, and soya bean trash.
 Other long fiber and solid biomass such as coarse grass,
shrubs, forestry trash, bamboo tops and twigs, and the likes.

APPLICATION OF PRESSED BIOMASS
Alternative energy to replace fossil fuel and to be used in furnace of boilers
to produce heat and steam that move turbines.
BENEFITS OF PRESSED BIOMASS
 Significantly cheap source of energy as it is made from waste.
 Irregular and huge volumes of agricultural biomass is pressed and
shaped into uniform blocks that make it easier to transport and
storage.
 High density of Pressed Biomass contains higher calorific value per
volume unit.
 To reduce the burning of agricultural waste and vegetation in the
plantation and forestry areas.
 Environmentally friendly as biomass is one of renewable resources of
which usage is neutral in the cycle of green house gases.

POTENTIALS OF SUGAR CANE TRASH
• Sugar cane areas in Indonesia in 2004 covered
341.621,7 Ha (Subiyono & Wibowo:2005). Sugar
cane production totals 27 million tons a year.
• Proportion of sugar cane waste stands at 30 tons/
Ha/year, meaning that as much as 19 million tons
of biomass (exclude bagasse) is available in
Indonesia per year.
• This huge potentials can boost the efficiency of
sugar mills and also the economy of local inhabitants
if it is utilized and not just be burned at fields.

BENEFITS FOR SUGAR OR OTHER MILLS
 Pressed Biomass that is made from sugar cane leaves
and tops can replace fossil fuel (diesel oil, gas and coal)
as feed stock for boilers.
 The increasing supplies of fuel as a result of the
utilization of Pressed Biomass will increase steam and
electricity generating efficiencies.
 The utilization of biomass can reduce the burning of
sugar cane trash at fields and contribute to the
promotion of renewable energy.
 An opportunity to gain Carbon Emission Reduction
(CER) facilities under the Clean Development
Mechanism (CDM).

PROSPECTS OF ELECTRICITY GENERATION FOR MILLS
 Replacement of boiler and steam turbine with higher pressured ones will increase generating capacity
and the electricity surplus can be sold to local or regional grid (Remodeling of Energy Basis).
 Construction of 10-MW to 30-MW power plant utilizing biomass fuel adjacent to mills will boost
sales arising from electricity that is connected to the power grid (Cogeneration).

A BUSINESS OPPORTUNITY FOR COOPERATIVES AND SME
Sugar cane farmers can utilize sugar cane waste by setting up Biomass Mills, under the management of
cooperatives or small/medium scale enterprises (SME), and become suppliers of this new fuel to:
1. Big companies that operating boilers and turbines such as sugar mills and power plants that use biomass as a
source of energy.
2. A high technology project that convert biomass into liquid fuel through Biomass Gasification and Gas to
Liquid (GTL) processes. (see illustration on page 10).

11. OUR STRONG COMMITMENT TO DEVELOP
HIGH QUALITY AND ENERGY-SAVING TECHNOLOGY
FOR MORE THAN 20 YEARS WE HAVE DEVELOPED HIGH QUALITY AND EFFICIENT
TECHNOLOGY WHICH INCLUDE:
 Modification of boilers from oil-firing to coal or biomass-firing ones. This includes installation
of supporting equipments that make Pressed Biomass is applicable to any boiler.
 Complete process, fabrication and installation of Organic Fertilizers Mill that make use
agricultural waste and cattle dung as feed-stock. This technology support organic agriculture and
reduce the consumption of natural gas in the fertilizers industry.
 Sterilizers with autoclave window using hydraulic system for palm oil mills. This method
avoids steam leakage from boilers so that increase the oil extraction rate of CPO mills.
 Retreading (vulcanizing) machine for used car tires utilizing a fully controlled-air pressure and
temperature; and support recycling program.
