Development of a plant to recycle batteries into micronutrients.
On 6th June 2018, Tracegrow announced the successful commissioning of its new plant in Kärsämäki which recycles batteries into micronutrients and other reusable materials.
The technology, developed by Tracegrow, is used to extract and purify the trace elements, zinc and manganese, from used alkaline batteries and recirculate them as ecologically clean zinc- and manganese-based micronutrient products for farming. Other components of batteries, including carbon, iron and nickel, are all recycled for further use, such as in the production of metal goods or energy.
Tracegrow's production process begins with a mechanical pretreatment stage to crush the batteries into an alkaline mass. After this, the mass undergoes a leaching stage. Subsequently, the solids are separated from the solution which is then transferred to the purification stage where unwanted substances can be removed. After purification, the generated solids are separated and the solution is neutralised at about pH 4.
From the beginning of June 2018, test batches of 10 cubic metres per week of finished products have been produced at the facility. Tracegrow is aiming to start full production capacity in spring 2019.
