At the Tumlingen location, fischer has permission to take water from its own spring, which is used for indirect cooling purposes in the production department and for irrigating the green areas.
The drinking water consumption at the Tumlingen location has remained constant, despite an increasing number of employees, and is about 10,000 m³ per year. The increase of source water consumption from 2017 to 2018 can be traced back to the long summer period in 2018 and the resulting high demand for cooling and irrigation. The percentage of drinking water from the overall water consumption was reduced.
When it comes to weed control, fischer says ‘no’ to herbicide. For this reason, a device was created in 2017, that uses the hot water method. This is an intense, deepacting method that permanently removes weeds, while protecting surfaces and the environment. This makes the usage of herbicides on paved areas completely superfluous and reduces overall usage by a third.
Sustainable handling is also observed in all processes at fischer. We are always developing, implementing new analytic approaches and the latest methods to identify potential ways to help save resources and energy while optimising processes. To do so, we conducted our first analysis using the “Material Flow Cost Accounting” (MFCA) method as part of the Material Efficiency Program from Umwelttechnik BW (EFFiMA). In addition to costs, the analysis considers all material and energy consumption, as well as loss quantities.The findings from this pilot workshop will now be expanded to other products and processes.
Process improvements in our chemical
production are one example for how resources are being used responsibly. There, dusts produced during solid materials dosing are suctioned and collected in separate types for reuse. This helps save material and disposal costs, reduce the volume of specialised waste by 3 t per year, and improve occupational safety through more efficient suction.
Ocean and air cargo packaging was also optimised, with a focus on reducing costs. As part of the optimisation several sustainability aspects were also addressed. These include, for instance, lowering packaging costs, levelling employee capacities, reducing injury risks and a significant reduction of packaging materials used by 32 t
Changing the manufacturing process for safety screw produced in-house helps to improve all three pillars of sustainability. The new process avoids so-called deburring scrap. The process saves resources by avoiding 42.6 t of metal scrap per year, and machines also do not have to be cleaned using a process that can often be complex. This improves ergonomics for employees and machine production times. In addition, we save by reducing manufacturing costs for raw materials by 15%.
The cutting oil used in machining in metal production directly influences the machine tools. Changing to a higher-quality oil significantly extends tool service lives, while reducing tool costs by 41%. Filtering and recovering the oil has generated added cost savings.
Generally, our collaboration with fischer suppliers represents a vibrant partnership. It is characterised by mutual appreciation. The following principle applies: “It is not easy to supply us, but whoever manages it does so as our partner.” If suppliers fulfil the high requirements relating to quality, environment, innovation and costs, they are welcome to engage in a long-term partnership with fischer.
In order to make an important contribution to the future and to corporate earnings, the fischer group of companies and its partners constantly and consistently search for ways to design products more simply and more affordably while maintaining consistently high quality. At the same time, less material should be consumed. In-house this is described as refinement.
The linking of lean management approaches with sustainable resource efficiency offers high savings potential along the entire value creation chain. For fischer Consulting GmbH, value stream mapping – with the aim of sustainable removal of waste in terms of “lean” and “resource usage” – is the focus of the consulting. In addition to in-house company process interfaces – both suppliers as well as end users – this includes both suppliers and end users. It is critical that, in the future, development, planning and production departments will work together as early as they can in order to create general conditions at the start of the product development process, which ensures the most efficient and resource-conserving manufacturing of products and provision of services possible.
Experience shows that the company is laying the foundations for a sustainably positive environmental balance, and thereby profits for all process partners, by successfully implementing the fischer Process System principles
