Tchibo sites & shops: the climate-friendly operation of roasting plants
Whether for coffee roasting, heating administrative buildings or lighting Tchibo shops, we consume energy on a daily basis in the operation of our locations. We are constantly working on using electricity and heat as efficiently as possible, thereby reducing our CO₂ emissions. At our energy-intensive roasting plants we have introduced an energy management system in accordance with ISO 50001 with which we aim to reduce the specific energy consumption per ton of roasted coffee by at least 1.5% every year compared to 2013.
All Tchibo locations in Germany exclusively use ok-power-certified electricity from renewable energy sources. This includes our two roasting plants and distribution centres, the company's headquarters in Hamburg and all Tchibo shops for which we buy the electricity for ourselves. Only a few Tchibo shops in malls are powered with electricity by the shopping centre’s operators. ok-power certification guarantees that the electricity comes from renewable sources and that its producers participate in the expansion of renewable energy beyond statutory requirements.
Increased efficiency through organisational and technical improvements
In recent years we have focused our savings targets on processes in the roasting plants. In 2013 for instance, we implemented an energy management system according to DIN EN ISO 50001:2011 which resulted in the introduction of organisational and technical improvements at our two roasting plants. This enabled us to reduce our energy consumption per ton of roasted coffee in 2014 by 2.3% vs. the previous year, well above our savings target of 1.5%. The idea behind the energy management system is to productivity and energy efficiency in production. To this end, we analysed variables such as plant utilisation, outside temperatures, product ranges, and catalytic converter temperatures in our roasting plants. The impact of construction projects was also considered in detail. In 2014 we reviewed the results and used the findings to optimise our processes. The energy management system owes its effectiveness not least to the efforts of our employees, who actively contribute ideas for identifying and exploiting further potential for energy savings.
