Case Study: Green Office

Green Office is a document and printer solutions company that was conceived in 1997 as a remanufacturer of used printer cartridges and has since developed into a comprehensive end-to-end solution for the document environment. The head office is based in Pinetown, KwaZulu-Natal (KZN), with satellite offices in Johannesburg and Cape Town. The KZN plant implemented the Energy Management System (EnMS) in 2015 as a means of reducing the office’s energy consumption.

In an adjacent office space to the KZN plant, the company established Green Able, a non-profit organisation (NPO) that recycles plastic from old cartridges. The remanufacturing facility in Pinetown receives used cartridges from customers then strips them down and replaces out any worn parts before refilling them for further use. Redundant cartridges and parts that cannot be used in the remanufacturing process are recycled by Green Able.
 
The KZN plant was approached by the National Cleaner Production Centre of South Africa (NCPC-SA)’s Industrial Energy Efficiency (IEE) Project for an energy efficiency assessment in 2012. Significant improvements have since been made and the key findings are as follows:
 
Key Findings
Over the 2015 period, 1 project was undertaken, resulting in a total energy saving of 31 450 kWh, valued at R46 200, with a total investment of R42 000, resulting in an average payback period of 1 year. A reduction of 30.1 tonnes CO2e was achieved.
