Industrial heat case study 2: Gasification of paper reject to displace natural gas usage in a pulp and paper process
The case study on replacing natural gas with a paper reject gasifier is a good example of how industrial processes can be converted from fossil based operation to partly bio-based operated processes. The Eska gasifier successfully managed to reduce natural gas usage and associated CO2 emissions. Besides that, for the site the total waste produced was also reduced and they successfully turned waste into value.
For businesses that have a large usage of natural gas to produce high temperature heat, this example will show how their business can change and manage to be successful. Furthermore it shows that overall the emission profile is improved, hence the marketability of their products will improve.
The message for policy makers is that changes business this way often is not easy. Often companies face difficulties in obtaining the right permits, find social acceptance and/or obtain sufficient funding (for capital investments or for reducing operating costs). However, the when successful the result is a decrease usage of natural gas, additional employment and an improved emission profile.
