Lewatit® Scopeblue
Lewatit® Scopeblue – First sustainably produced ion exchange resins
The new product family initially encompasses three new weak acid cation (WAC) exchange resins. These products are marketed under the LANXESS Scopeblue sustainability umbrella brand. It was created for products that either exhibit a sustainable raw material content of more than 50 percent or offer a carbon footprint of less than half that of their conventional counterparts made from conventional raw materials.
The new resins Lewatit® S 8227 Scopeblue, Lewatit® S 8229 Scopeblue, Lewatit® S 1567 Scopeblue and Lewatit® CNP P Scopeblue, which are used primarily for the partial softening of drinking water, actually meet both criteria. The Scopeblue resins have a carbon footprint that is up to 61 percent smaller than conventional types and consist of more than 90 percent renewable raw materials. In accordance with the mass balance approach they are chemically identical to conventional products and are produced in the same plants using the same processes.
LANXESS has also recently started producing styrene-based weak base anion (WBA) exchange resins – Lewatit® MP 62 WS Eco and Lewatit® S 4528 Eco – based on sustainably produced styrene. These are used primarily in the treatment of wastewater and chemical process flows as well as in the food industry. Due to the more complex synthesis pathways, the percentage of conventional raw materials in the end product cannot be reduced to the same extent for these resins as it can for WAC resins. LANXESS is demonstrating that these resins, too, which bear ‘Eco’ in their name, were produced using sustainable, bio-based or recycled raw materials.
Mass balancing – transparent and certified
Renewable or waste-based raw materials are allocated to the corresponding quantities of sustainable products using the mass balancing method. To manufacture mass-balanced products, raw materials or precursors that are demonstrably sustainable in origin are deployed and allocated to selected products using a special accounting method. This allows renewable raw materials to be integrated in existing production and supply chains.
The production plant for the sustainably produced resins in Leverkusen and the mass-balanced products are independently certified beforehand. In the case of the ion exchange resins, certification according to ISCC PLUS (International Sustainability & Carbon Certification) demonstrates that the criteria for reliable balancing are met and correctly applied.
Scopeblue: Frequently asked questions (FAQ)
Here we answer the most frequently asked questions about Scopeblue and its possibilities of use.The LANXESS Group defined the following ambitious criteria for its products in order to become part of the Scopeblue corporate umbrella brand:
- min. 50 % reduction of product carbon footprint (PCF) compared to conventional product
and/or
- min. 50 % of certified recycled, biomass-based or renewable raw materials are substituting fossil raw materials compared to conventional product
PCF reduction as well as raw material share are reviewed internally before a product is permitted to be labeled “Scopblue”.
Under ISCC PLUS the following three raw material categories (arising at the beginning of the supply chain) can be certified:
- Bio feedstocks are derived from virgin biomass, whereas biomass refers to the biodegradable fraction of products from agriculture, forestry and related industries including fisheries and aquaculture, e.g. corn, sugarcane, rapeseed etc.
- Circular feedstocks are materials at the beginning of the supply chain considered as a waste/ processing residue that are not landfilled or energetically used, but instead re-used, further used or recycled in a loop without dropping out of the economies’ value chain
- “bio-circular” refers to waste and residues of biological origin from agriculture, forestry and related industries including fisheries and aquaculture, as well as the
biodegradable fraction of industrial and municipal waste (e.g. used cooking oil, tall oil, food waste, etc.) - “circular“(incl. technical-circular) means feedstock derived from the mechanical and/or chemical processing of recyclable materials of non-biological origin (fossil-based) (e.g. mixed plastic waste, waste textiles, end-of-life tires, etc.).
- Renewable feedstocks cover materials of non-biological origin, derived from a process using renewable energy sources other than biomass, e.g. electricity for production of chlorine, caustic soda and hydrogen from rock salt (sodium chloride). Electricity generated from renewable energy input like wind, solar, aerothermal, geothermal or water (including hydrothermal sources, waves and tides) (renewable electricity) can be used to produce sustainable materials under ISCC PLUS
