Mineral material recycling: a question of responsibility
According to the monitoring reports of the Kreislaufwirtschaft Bau, the annual demand of the German construction sector for mineral construction materials adds up to around 550 million tonnes. Worldwide, it amounts to around 50 billion tonnes (UNEP). These quantities are needed by the construction industry, e.g. for the creation of housing or the construction and maintenance of essential infrastructure. In this context, recycled aggregates, the result of high-quality construction material recycling, together with other substitute aggregates, not only contribute to the conservation of natural raw materials. They also significantly reduce the consumption of land.
Large-scale resource and landscape conservation
In its 2019 report, the UN Environmental Programme predicts an annual global increase in demand for primary mineral materials of 5.5 %. According to the report, sand and gravel resources are the second largest resource, after water, to be mined and traded. In this context, the recycling of mineral waste is urgently needed. The activities of mineral material recycling not only ensure a sustainable approach to nature, but also guarantee a reliable supply of important construction materials. At the same time, the impact on the landscape is reduced – in two ways, because mineral recycling reduces the loss of natural space through the extraction of primary resources and at the same time avoids the use of land for the disposal of material that can actually be reused.
In regard to sand & sustainability, UNEP published ten strategic recommendations to avert a crisis. more
Our contribution: sustainable resource creation
REMEX is a specialist for the best possible recycling and reuse of minerals. We produce secondary construction materials from soil and road construction waste and the demolition of old buildings, but also from ash and slag from industrial production, power stations or waste incineration plants. Intelligent processing in REMEX plants produces high-quality recycled aggregates and quality-assured secondary aggregates. Our branded aggregates REMEXIT and GRANOVA offer customers a wide range of applications due to well-defined chemical and physical properties and strict quality controls. REMEX also extracts large quantities of ferrous scrap and other valuable metals from mineral waste, which are returned to the material cycle.
Recycling of various mineral materials
Construction and demolition waste as well as ash, slag and dust are the input materials for REMEX secondary construction materials; the results are recycled and secondary aggregates for earthworks and road construction as well as civil engineering.
Towards a closed cycle
How can the recycling of construction materials or the general recycling of minerals contribute to a sustainable raw materials strategy?
Greater awareness of the limited availability of mineral resources
Opening up further fields of application for recycled and secondary aggregates
Development of future-oriented processes for even higher recycling rates
Equal treatment of quality-assured recycled aggregates and primary aggregates
Greater consideration of recycled aggregates in public tenders
Binding reuse regulations – uniform national requirements instead of isolated solutions
Global knowledge transfer
Organisation and development of mineral material cycles, also internationally
Our engagement in associations
We are committed to promoting the interests of the circular economy at both national and international level, and in this context we are involved in the following associations and industry bodies.
