Reducing Emissions from Combustion of Grape Residues in Mixtures with Herbaceous Biomass.

The use of grape residues as a renewable energy source for combustion presents various problems. One of these is the excessive production of carbon monoxide and nitrogen oxides. Analyses and combustion tests were performed on white and red grape pomace as well as grape stems.

Impact of Torrefaction on Fuel Properties of Aspiration Cleaning Residues.

To maximise the use of biomass for energy purposes, there are various options for converting biomass to biofuels through thermochemical conversion processes, one of which is torrefaction. Higher utilisation of waste from the aspiration cleaning of grains, such as wheat or maize, could be one of the means through which the dependence on fossil fuels could be reduced in the spirit of a circular economy. In this study, the effect of torrefaction on fuel properties of agricultural residues was investigated.

Energy Utilization of Torrefied Residue from Wine Production.

A significant amount of waste is generated in the food industry, which is both an environmental and an economic problem. The recycling of this waste has become an important area of research. The processing of grapes produces 20-30% of the waste in the form of grape pomace and stalks.

Changes in the Composition and Surface Properties of Torrefied Conifer Cones.

The paper investigated the torrefaction of cones from three tree species: Scots pine ( L.), Norway spruce ( L.), and European larch ( Mill.
