The Hein Heun Groep adheres to the principles of recycling and has defined this in its business operations. This is the reason why we have the philosophy that all used materials have to be reused in a new cycle, without creating residual products that would still have to be sent to a landfill. This is also called the Cradle to Cradle philosophy, which is part of our CSR (Corporate Social Responsibility) (Performance Ladder level 3).
During our projects we always adhere to green decommissioning (sustainable decommissioning) and we create a substance inventory in advance. This inspection we do in advance provides insight into the products and raw materials that lend themselves to high-quality reuse and/or recycling, and even aids in determining whether complete (parts of) buildings can be reused. The first step in that process is the removal of all parts that can be reused immediately. Examples of this are, among others, complete units, wall sections, the removal of advertisement, lighting, sound equipment, plumbing, (aluminium) frames, etc. These dismantled parts are, if possible, transported directly to a dealer or to our warehouses where they are sorted and stored until a later reuse. After this is done the stripping of objects is continued, during which all non-stone-like materials are removed. Examples of this are the complete dismantling of system interior walls, insulation, and also hard mineral ceiling tiles (which are sent directly back to the supplier for reuse). Any other released waste flows are immediately sorted into mono-streams (lots of one and the same material) and transported to a nearby processor, so that no unnecessary transport has to be done (CO2 reduction). In doing so, these mono-streams are returned to the industry as raw materials for new products. Examples are:
- Waste wood from industrial and wood processing companies is processed into secondary raw materials and fuels. Examples are pallets, beams, planks, and sleepers. Natural wood (A-wood) is used as a raw material in the chipboard industry. The remaining wood (B- and C-wood) is reprocessed into secondary fuel for biomass plants.
- Plastics (eg. PVC piping, etc.)
- Bituminous mixtures (eg. Roofing)
- Metals (ferrous and non-ferrous)
- Insulation (various types) are mixed with new products
- Flat glass is recycled into new glass
- Materials containing gypsum (eg. Metal stud walls, ceilings)
- Other construction and demolition waste
- Waste from organic solvents and refrigerants (eg. Freon from air conditioners)
- Electronic and radioactive wastes (smoke detectors)
- Rubble is processed into granulates in various grain sizes. These are reused as foundation material in road construction or as gravel substitute in the concrete mortar and concrete products industry.
At our department Hein Heun Milieu, third parties, such as industrial companies, stores, institutions, and private households, also deliver their waste. This is then sorted again in several halls in the same way as mentioned above. Doing so has made us a leading company in the Netherlands in waste logistics, waste management, and waste recycling.
