Where Does RECLIME® Fit into Sugar Production?

RECLIME® operates during the raw juice purification stage, where calcium compounds (Ca²⁺) are used to remove non-sugars and improve juice quality before evaporation, crystallisation and drying. By enabling their controlled recycling and reactivation, the system helps reduce fresh lime consumption while maintaining stable purification performance.

RECLIME® Recycling Unit

The RECLIME® system is installed as a separate technological unit that complements the existing purification process. It processes 1st Carbonation Slurry and separates it into two controlled fractions in the RECLIMER: a concentrated CaCO₃-rich fraction suitable for recycling, and a lighter fraction containing the majority of non-sugars.

The recycled CaCO₃ fraction is stabilised in the Homogeniser and chemically reactivated in the Reactor by the controlled addition of milk of lime. This produces RECLIME® milk, which is dosed back into selected stages of raw juice purification.

By reusing calcium compounds (Ca²⁺) already present in the process, the system can reduce fresh lime (CaO) consumption to approximately 0.4–0.8% per beet, depending on operating conditions, while supporting stable purification, improved sedimentation and better filtration performance.

Reducing CO₂ emissions and raw material transport

RECLIME® reduces CO₂ emissions, raw material demand and transport requirements through lower consumption of limestone and coke, as well as reduced filtration cake production in the purification process.

Under typical operating conditions, this corresponds to a reduction of 3.5–6.9 tonnes of CO₂ per 1,000 tonnes of processed beet, together with a reduction in transported raw materials and by-products of 13–26 tonnes per 1,000 tonnes of processed beet.

For a sugar factory processing around 1.2 million tonnes of beet per campaign, this represents a reduction of approximately 5,830 tonnes of CO₂ emissions and a decrease in transported materials of around 21,660 tonnes annually.
