“…In agriculture, filter cake is used as a fertilizer, and is applied directly or indirectly (as compost) on the sugarcane fields [5,14,15]. Filter cake has also been applied as a structural soil amendment to counteract soil degradation that leads to soil erosion and compaction [16].…”

“…The use of filter cake as fertilizer or soil amendment is widely accepted and is practiced in almost all important sugarcane producing countries. Therefore filter cake may be considered as a by-product with economic value [14,15], rather than as a waste [5,14]. However, the direct use of filter cake also presents risks and limitations:…”

“…Most of these mainly focused on recycling and energy use of the residues (filter cake, bagasse). In particular filter cake was considered for a long time the main solid waste of the cane sugar production [5,8,9], with an annual production estimated at about 29 million ton and with high potential environmental impacts. The filter cake has generally been used as fertilizer in the cultivation of sugarcane.…”

Sugar from sugarcane represents 65-70% of the world production of sugar and its production is mainly located in developing countries. The production process requires high amounts of steam and electricity at the different stages, and generates important quantities of residues. A major residue of the sugar production is filter cake (in Cuba: Cachaza), the residue from cane juice filtration. Filter cake causes significant pollution, and in several sugar factories it is considered a waste, posing problems of management and final disposal. This paper reviews recycling and recovery opportunities of filter cake (and bagasse) and experimentally studies the use of filter cake as fuel at the sugar factory. Filter cake may e.g. be used as a fertilizer/soil improver directly applied on the fields or after composting. During its decomposition, it generates, however, an acid leachate and emits significant amounts of greenhouse gases. Moreover, the experimental part of the paper shows that blends of filter cake with bagasse can be combusted in industrial boilers in sugar factories, and that loose, non-vitrified ashes with a similar appearance as bagasse ash are obtained. This results in lower volumes and masses of residues to be transported, so that transportation costs are reduced. Moreover, it gives a new economic value to the filter cake, and reduces its environmental impact. When all filter cake would be combusted blended with bagasse, about 25% more ash would be obtained than for bagasse and the trace element composition would comply with the regulatory limits for use as fertilizer/soil improver.
