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.
