Rivertop moves from lab to pilot-scale for renewable glucarate

19 March 2012

Renewable chemicals company Rivertop Renewables has upgraded its patented process technology from the lab to pilot manufacturing.

As part of the upgrade, Rivertop has entered into a contract agreement with US-based manufacturer of fine and speciality chemical products, DTI, to pilot the manufacture of its sustainable glucarate-based products.

Rivertop said product made in the initial phase of contract manufacturing will be used to fulfil its commercial contracts for bio-based corrosion inhibitors, while remaining volumes will be used by the company and its customers to develop and test glucarate applications in other industrial and consumer markets.

Rivertop plans to use its glucaric acid products as a replacement for phosphates in the markets for detergent builders, corrosion inhibitors and chelants to protect transportation and industrial infrastructure without damaging water quality.

Starting in February 2012, Rivertop's pilot manufacturing utilised DTI's manufacturing technologies to enable the scaling of its platform oxidation process to produce batches of glucarate-based products at approximately 850 pounds per run.

Data derived from these and subsequent runs will enable Rivertop and DTI to scale to a capacity up to 10 million pounds of contract-manufactured product per year.

The next scale of production is scheduled to be commissioned in the fourth quarter of 2012.

Rivertop is engaged in supplying sustainable, biodegradable and non-toxic chemicals and bioproducts derived from renewable plant sugars.
