What is Biomass ?
Biomass is carbon based. In the context of biomass for energy this is often
used to mean plant based material, but biomass can equally apply to both
animal and vegetable derived material.
Biomass Basics
• Biomass Categories:
• Virgin woods: from forestry, arboricultural activities or from wood processing
• Energy crops: high yield crops grown specifically for energy applications
• Agricultural residues: residues from agricultural harvesting or processing
• Food waste; from food/drink manufacturing, preparation/processing, and post consumer waste
• Industrial waste and co-products: from manufacturing and industrial processes
12
Basic Carbon Background
• Plant Material (biomass): The carbon used to construct biomass is absorbed from the
atmosphere as carbon dioxide by plant life, using energy from the sun.
• Fossil Fuels: Fossil fuels such as coal, oil and gas are derived from biological material,
however material that absorbed carbon dioxide-CO2 from the atmosphere many millions of
years ago.
• Plant Material (biomass) vs. Fossil Fuels: the difference between biomass and fossil fuels is
one of time scale.
• Biomass: Takes carbon out of the atmosphere while it is growing and returns if as it is
consumed.
• Composting and Anaerobic Digestion are conversion technologies that consume carbon
• Composting: Biological decomposition of carbon done in the presence of air (oxygen
present)- no renewable biogas as a by product; not an energy producer
• Anaerobic Digestion: Composting without air (oxygen)- renewable biogas (methane-CH4)
as a product; is an energy producer
13
14
Anaerobic Digestion
It is the natural process that converts biomass to energy under oxygen free
conditions. The two most important considerations in converting the biomass
to renewable biogas are the input materials and the environment of the
bacteria (bugs) within the digester.
* Be careful of biological inhibitors that may be part of input
materials
* Approximately 60% of volatile matter consumed
* NPK unaffected and pass through
* Trace Metals unaffected and pass through

EnviThan – Gas-upgrading with high-selective Membrane
35
• Membrane – a thin separation layer through which substances can penetrate in a limited
way
• Retentate – a by the membrane held back fluid (e.g. CH4)
• Permeate – a fluid that entered through a membrane (e.g. CO2)
• Selectivity – preferentially react or sort, it means separation of fluids
• Permeability – permeability or the flow through a membrane
• Separation-capacity – is a combination of selectivity and permeance and describes the
efficiency of a membrane
• Partial pressure difference – the pressure difference of the partial pressure of a gas on the
retentate (interior of hollow-fiber) and the permeate side (space outside the hollow-fiber) is
the driving force for the permeation

• Methane loss < 0.5 % possible, but about 0.8 % will be set for RTO
• Methane concentration over 97 % in the retentate possible
• Power consumption approx. 0.2 kWh/Nm³ raw-biogas
• Raw-biogas must be free of hydrogen-sulfide, ammonia, particulates, condensable material
and oil
• There is no need for water and the gas-upgrading works free of waste-water, apart from a
small amount of condensate from the cooling-process
• Output pressure is slightly below to the working pressure 11 bar absolute
• Modular structure of the gas-upgrading
• Small footprint
• No additional drying necessary
• It is possible to take heat back from the system (e.g. for the digester)
• Start-up time at full load in just a few minutes
• Partly-load operation is no problem, good controllability through pressure and volume-flow
• Low operational & maintenance costs
• No chemical- and heat-consumption needed
• Operating-pressure 11 bar absolute, operation temperature approx. 25 up to 28 °C
