Ecological and Economic Assessment of Resource Use - Remanufacturing of products

Remanufacturing offers the opportunity to keep products or components in the economic cycle – even beyond their originally planned service life, thereby contributing to the circular economy.

Ecological and Economic Assessment of Resource Use - Industry 4.0 retrofit measures on machine tools

Retrofitting instead of buying new: Modern systems are needed to make production in manufacturing companies fit for Industry 4.0. But instead of buying new equipment outright, many existing machines can also be adequately upgraded.

Tools to discover

Online tools for more resource efficiency: Reducing material and energy consumption helps to cut costs and make businesses more competitive. The following tools help companies to identify their potential for resource efficiency and how to realise it.

  • Cost Calculator
    • Cost Structure Calculator

      This module allows you to display the cost structure in your own company. Users are shown which areas in the company are key cost factors and what proportion of the company's costs are accounted for by material and energy costs. In addition, the operational cost structure can be compared with the respective industry averages.

      Cost Structure Calculatore
    • Material Flow Cost Calculator

      This module provides an introduction to the detailed material and energy flow-based evaluation of production processes based on the DIN EN ISO 14051 standard. The calculator provides support through a structured input option and a graphical representation of the production process. By quantifying loss costs, material and energy consumption can be localized within the company.

      Material Flow Cost Calculator
    • Investment Calculator

      With this module, investments can be compared on the basis of life cycle costs. The amortization periods of various new investment alternatives can be clearly calculated. The basis for this is the dynamic amortization calculation. The inputs for the amortization calculation are based on the VDMA standard sheet 34160.

      Investment Calculator
  • Resource Checks
    • Base Module

      Learn how to reduce material losses caused by rework in production, as well as how to lower your overall energy consumption.

      Base Module
    • Foundry Technology

      In order to save material and energy, it is worth taking a look at the energy-intensive melting process, for example, the scrap rate or the amount of waste.
