biomass

The starting point for the estimation of the potential for biomass use in industry is the resource potential of biomass inputs.

Competition for biomass among different sectors

Iron and steel

Iron production requires the combustion of carbon-containing fuels to produce carbon monoxide which is reacted with ferrous oxide to produce iron and CO2. Historically, iron was produced using charcoal exclusively as fuel. At the beginning of the 18th century, charcoal started to be substituted by coke. Coke is now by far the dominant fuel in iron and steel making, with at least 10 Gt of coke being consumed per tonne of steel produced. Even so, significant amounts of pig iron are still successfully produced using charcoal.

Petrochemical feedstocks

Carbon is also needed for the production of materials in the petrochemical sector, where it comprises around 75% of the total feedstock.

The main alternative feedstock to fossil fuels in the petrochemical sector is likely to be biomass. But waste products, such as recycled plastics, can also substitute for some fossil fuel feedstock. Alternatively, organic materials such as cellulose fibers, coconut fibers, starch plastics, fibre boards and paper foams can be produced which can directly substitute for petrochemical products in end use applications, as described in Annex 3. It is also possible to produce textile materials (mainly viscose and acetate) from wood pulp and as by-products from cotton processing.

Transportation

The transport sector is likely to be a significant competitor for any available biomass resource. If by 2050 biofuels are still the main option to displace fossil fuels from the transport sector, the availability of biomass for the industrial sector may be extremely limited. This would increase the attractiveness of other, non-biomass, renewable energy sources and of the further electrification of many industrial sectors. But at the same time, if biofuels increasingly replace petroleum fuels, this may free up large amounts of refinery-produced naphtha at low cost. In these circumstances, shifting away from naphtha as a petrochemical feedstock to alternative feedstocks or processes will be very difficult to achieve.
