Michaela Hissa, a researcher at the University of Vaasa, has demonstrated that it is possible to use fuels made from industrial waste as a real alternative to reduce the environmental impact of high-powered engines.
Fuels derived from industrial wastes
Given the impossibility of renewing the vast fleet of existing engines in the short term, options such as direct replacement fuels, which are compatible with current systems without the need for modifications, are emerging. Among them, the following stand out renewable naphthaderived from crude tall oil generated in the paper industry, and marine diesel produced from used lubricating oils.
[post_relacionado]The research revealed that when mixed with diesel, renewable naphtha allows cleaner combustion, reducing smoke. Marine diesel, on the other hand, reduces emissions of hydrocarbons and carbon monoxide. carbon monoxide. Both contribute to a notable reduction of suspended particles, which are responsible for harmful effects on health.
Marine and off-highway machinery engines require efficient solutions compatible with extreme operational demands. These fuels fulfill that role without compromising performance, according to Hissa. Moreover, because they come from secondary sources such as hazardous waste or forestry by-products, they provide additional value in terms of circular economy.
The Finnish forest industry has an operational base for the production of wood-based fuels. production of wood-derived fuels.. However, its implementation at scale will depend on factors such as the continued availability of feedstock, the profitability of refining processes and cost competitiveness against conventional fuels.
