Recycling of waste where there is a positive carbon benefit, into a renewable resource is evidently the priority, prior to its consideration for other ends. What however remains non-recyclable needs to be recovered for maximum value and waste to energy provides a very efficient solution.
Pyrogasification involves high temperature thermal treatment of renewable biomass or non-renewable waste in the absence of oxygen. The resultant gas (syngas), liquid and coke can be produced in varying proportions and volumes according to a number of determinable parameters.
Whilst the most frequently practiced energy recovery method today of syngas involves its direct burning in a CHP motor, a secondary pathway involves the further process of methanation in order to produce a grid compatible gas for direct injection. The key attraction from an energy management perspective of this upgraded syngas is that it provides an opportunity to store and call up this calorific value according to demand. This “pyrogasification to biomethane/recovered gas*” route is set to make a major contribution to attaining the French 100% renewable green gas target for 2050 (from 15 to 40% depending on scenario).
Incineration by contrast, implies combustion in the presence of oxygen and the immediate recovery of the heat value of the incinerated feedstock.
* « Biomethane », when this syngas comes from biomass or renewables streams (EnR)
« Recovered gas » when this syngas comes from SRF non-recyclable fraction or non-recyclable waste.
FEDEREC is the Recycling Professional Federation. Created in 1945, FEDEREC brings together 1300 company members, from very small businesses to big groups, spread out on the whole French territory, and with activities such as collection, sorting, recovery of industrial and municipal waste or recycling feedstock trade.
« Today, wood recycling players are waiting for the start of class B wood combustion projects. » Pascal LEON, President of the wood and pallet sectors.
Xylowatt has accumulated over the years the most direct experience of any developer of gasification solutions in Europe. Its most recent release, the NOTAR® v.3 indicates a new level of attainment for the company in syngas production.
A world first : The Namur Hospital (CHU UCL) – Godinne site becomes the world’s first hospital mainly fed by green energy from biomass gasification. The CHU will benefit from this unit to cover a part of its needs in electricity (40%), heating (65%) and cooling (40%).
As it does not rely on wind nor sunshine, the new unit will produce day and night in summer and from local renewable biomass: 620 kW of electricity, 1100 kW of heat and 680 kW of cold. Its energy resources will include woodchips from natural wood (branches and cleaning from motorways sides) and recycled wood (not usable pallets and packaging wood).
ETIA is known the world over for its proven BioGreen© torrefaction and pyrolysis process converting biomass, plastics, and waste into energy and useful products. The first unit was installed in 2003 and over 90% of its business is in the export market.
In the pipeline today is the extension of the high-temperature pyrolysis Biogreen© process to become a technology to produce Synthane®, synthetic methane, from waste and biogenic resources by the addition of purification and methanation processes.
A collaboration with GRTgaz was launched in July 2017 to construct a pilot plant dedicated to produce synthetic methane from waste and biogenic resources and to validate the opportunity of injecting synthetic methane into transmission grid.
CHO Power designs, builds, and operates electricity production plants from SRF and biomass through its own gasification process. Onsite energy recovery via gas motors provides an excellent electrical output (two times higher than a vapor cycle).
CHO Power designed, built and operates the 1st plant of this kind (at European level, and even at global level) in Morcenx (Landes region, France). This plant, CHO Morcenx, is designed to recover 58,000T/year of industrial waste and forestry woodchips and it presents an installed capacity of 11 MWe.
