Waste streams

  • AkzoNobel provides performance coatings to many markets including transportation, construction and industrial markets.  Performance functions include anti-corrosion, anti-abrasion, antifouling and chemical resistance. The coatings are applied to many different substrates including steel, tinplate, concrete, aluminium, plastics and composites
  • AkzoNobel produces a huge number of coating formulations using a wide range of raw materials to achieve the required properties. The vast majority of raw materials is produced from petroleum feedstocks (e.g. resins and solvents) or from minerals (e.g. pigments), and as such are produced from finite resources. Other industries also consume raw materials produced from the same feedstocks further impacting the future availability of these materials
  • Paint manufacture typically produces a very high yield of product and the little waste that is produced can often be remanufactured into product. Other manufacturing industries however often produce by-products which in the past were simply disposed of as waste. In recent years efforts to find other uses for waste streams have intensified due to concerns about the effects of waste disposal on the environment. Additionally, tighter controls on waste disposal have led to higher costs
  • The use of waste streams can provide significant benefits to AkzoNobel in supporting the company’s sustainability aims, in particular carbon footprint reduction. Waste streams, while they may be fossil or mineral resource derived, could be considered a sustainable and economic  source of potential raw material
  • In order that any particular waste stream can be used in a paint formulation a number of key criteria need to be met. The product needs to be consistent in composition and in any important physical properties, for example color or particle size. The performance of the paint formulation, for example outdoor durability or anticorrosive properties, should in no way be compromised. Waste streams will invariably be produced in limited quantities and these quantities should be sufficient to be used in high volume coating formulations. Finally the cost should be lower or match the raw materials that the waste stream product is replacing
  • We invite proposals for materials that may otherwise go to waste, that can be incorporated into paint formulations without affecting the coating properties or adding cost

Possible materials may include but are not limited to:

  • Waste streams from agriculture, food processing and similar industries could be also classed as renewable
  • Ashes from processes that involve incineration which could be used as filler pigments
  • Residues from chemical processes that can be used in polymer manufacture
  • By-products from forestry or food processing industries
  • Materials generated at the end of life of other products
