    The first milestone was the definition of “sustainable development”. The 1987 Brundtland Report, named after former Norwegian Prime Minister Gro Harlem Brundtland, entitled “Our Common Future”, provided the impetus for the start of a sustainable world focused on a circular economy.


    » 1. Sustainable development is development that meets the needs of the present without risking that future generations will not be able to meet their own needs.  «

    » 2. In essence, sustainable development is a process of change in which the use of resources, the destination of investments, the direction of technological development, and institutional change harmonize to increase current and future potential to meet human needs and aspirations. «

    Quote from “Our Common Future” by Volker Hauff (1987)


    The development of the cost structure in companies shows the necessity of efficient energy and material flow management. The cost of materials is the most important cost item in the construction industry, and the trend is rising. 

    Three factors are largely responsible for this trend:

    • The rising costs of a shortage of raw materials can be easily understood with reference to steel and crude oil. In the construction sector in particular, such shortages pose special challenges for manufacturers and users of mineral bulk materials and concrete.
    • Construction companies and companies in the manufacturing subcontracting sector have increasingly reduced the vertical range of manufacture and are processing ever higher-quality materials.
    • The cost-cutting programs to date have largely been based on reducing personnel costs or optimizing process organization.


    How you can work more economically and ecologically sustainable with our solutions:  

    • Discover the potential to increase material efficiency and implement sustainable strategies and work practices with N1.
    • Identify environmental and economic potential from the reduction of unnecessary travel to the use of secondary raw materials. Only source primary raw materials when there are no other alternatives. Use our software tools to determine relevant delta quantities and unlock new cost reduction potential.
    • Optimize logistics costs for stable material costs and sustainable construction projects.


    Software from N1 increases the rates of recycling of excavated and demolition materials on construction sites and of residual materials generated during the extraction of primary raw materials. Our solutions are your tool for optimizing construction and production processes, material recycling, and the recycling or multiple use of raw and construction materials.
