How to feed the world in 2050?

In 2050, the earth's population will be 9 billion, 70% of whom will be living in urban areas. This growing urban population will need access to healthy and nutritious food. Governments and Non-Governmental Organizations (NGO's) are promoting fresh food consumption for health reasons along with the importance of producing safe food that is sustainably grown. In parallel consumers are becoming more health-conscious and are increasingly driven to local, natural, and sustainable quality offerings — a trend which is strongly tied to the modern focus on healthy eating. It is estimated that we will have to produce double the amount of healthy, nutritious food with half the resources of today. This leaves us with one of today's biggest challenges. Water, fertilisers, land and energy are crucial resources for food production. Less than 1% of the earth's fresh water is easily available and suitable for human use. 70% of that water is used for irrigation in agriculture. Water scarcity is addressed as part of the United Nations "Agenda 2030" Sustainable Development Goals. Reserves of fertilisers, that are crucial for the production of food, are running out. Continuous and increasing demand on land resources has had a negative impact on the area and quality of land available for food production. So, food production has to double while using half of the resources of today.

We place a high priority on sustainable business. As part of this we set up a professional (country-specific) recycling service for our clients. This service is designed to guarantee that used stone wool products are recycled responsibly.

  • During end-of-life processing, the material is segregated into three residual waste fractions: plastic waste, the remains of plants and stone wool granulate.
  • Residual drainage water is carefully separated, so as to prevent it from leaking into surface waters.
  • The organic waste can be used to make products such as compost.
  • The shredded substrate slabs, blocks and plugs are recycled into raw material in a low-energy process for various manufacturing processes like brick, cement, potting compost or soil improver production. Some of this raw material is turned into stone wool briquettes and used in the ROCKWOOL factory to create new stone wool products.
  • The plastic wrapping used for Grodan products is turned into plastic granulate and used in the plastics industry to manufacture refuse bags.

This re-use of resources from end–of-life products not only diverts waste from landfill, but also reduces the consumption of new raw materials, thereby reducing our impact on the environment.
