Technology – Approach

Aquavitrum’s approach to solving this problem was to start with a blank sheet, and take on the challenge from a radically different angle.

Typically MRF glass recovery has been attempted using dry sortation techniques; the results of which have not improved the quality of the glass output to an acceptable level. This method is costly, logistically challenging and glass is lost when handling the by-products of the process.

Over recent years, organisations have attempted to recover the glass cullet by configuring off-the-shelf equipment or wash plants (not designed for MRF glass), which have resulted in low purity, high wear and a ‘dirty’ product. These solutions require chemicals to generate separation, which can be unreliable and expensive.

Aquavitrum focused on studying the individual characteristics of the particles within MRF glass feedstocks. Significant differing behavioural characteristics were identified between the glass particles and contamination particles. From this the Aquavitrum Separator was developed and has been proven on an industrial scale. The collaboration with the University of Southampton underpins our claims with scientific academia.

Aquavitrum’s patented technology separates the glass from the contaminants in a body of recirculated water using no chemicals. The feedstock can be stored outside which eliminates any pre-processing requirements due to moisture content.

This technology is robust, has no moving parts, and the unique way the separator operates dramatically reduces wear.
