Turmeric Spent Extraction Process

Turmeric powder can be extracted using several different methods, including solvent extraction, supercritical fluid extraction, microwave assisted extraction and steam distillation. These methods leave behind residues called turmeric spent, which are considered to be insoluble waste.

Turmeric Spent Applications

Turmeric waste can be dried and processed into a fine powder or small bits, which are burned directly as a fuel source in industrial furnaces or boilers. This loose biomass can also be used as a raw material to manufacture briquettes or pellets, which are then burned directly in place of coal to produce heat and electricity.
