Practical implementation of circular economy with ifu Hamburg

What is circular economy?

The circular economy concept is focused on reducing resource consumption. In some contexts, this term is limited to the field of waste management, often focusing on recycling quotas, material recyclability, and waste reduction, especially packaging. We like to look at circular economy in a much broader context, though. What we see is an economic system that can function without any waste or residual materials. All materials leaving a production process will either be recyclable and used again in the same process, or serve as a valuable resource in a different process.

Realizing circular economy at the industrial level

We support the vision of a circular economy but are aware of the difficulties that businesses are confronted with when trying to transform their operations. We would like to support businesses in their efforts to integrate a circular economy perspective into all their innovative processes. Part of the process is to create a systematic basis for mid- and long-term planning. Achieving a genuine circular economy across all industries and production systems simultaneously won't be feasible, but it is entirely possible to start improving efficiency within a particular production system step-by-step. This is, of course, still a big challenge, one that begins with a comprehensive understanding of all the material and energy flows involved – not just the waste products. If you'd like to be a leader in implementing these first steps in your business, we're here to support you with our consulting services and software solutions.
