IntroductionSolWaste presents a methodology to define a roadmap for the abattement of non sustainable industrial waste abatement while minimizing waste management costs. To do so, SolWaste provides: - A Waste diagnostic methodology including data preparation & ideation workshops focusing on most impacting production units & waste streams.
- A set of proven best practices to better manage industrial processes in a more sustainable way at lower costs.
- A library of key technologies allowing for more sustainable & less costly waste treatment solutions.
The scope of this standard includes : - Non-hazardous liquid and solid waste treatment; gathering, recovery and disposal of non-dangerous waste.
- Hazardous liquid and solid waste treatment; gathering, recovery and disposal of dangerous waste.
- Products or by-products treated or valorized by a supplier at a cost for Solvay, being or not classified as waste.
- Expenses paid to collect (manpower supplied and/or rental equipment), transport, treat, and valorize the waste, including all taxes related to such waste streams.
- Scope of technologies and waste treatment services within this package (recovery/ recycling, incineration with/without energy recovery, landfill).
Key DefinitionsBy-products: a material that is not deliberately produced but is produced as an integral part of the process, for which there is a certain reuse application without further processing. The definition of a waste can vary from one country to another. More details in the Regulatory Guidelines for Waste initiatives. Waste: usually described as any substance or object which the holder discards or intends or is required to discard. The definition of a waste can vary from one country to another. More details in the Regulatory Guidelines for Waste initiatives. Non Sustainable Industrial Waste (NSIW) : any waste that is landfilled or incinerated without energy recovery. The Reference for (non) Hazardous classification of a waste can vary from one country to another. More details in the Regulatory Guidelines for Waste initiatives). Data collection- Consolidated table of volumes, costs, Haz / Non Haz classification and treatment method for all waste streams;
- Block diagrams at plant-level to map main Waste flows;
- Integrate data from Material Use workstream (cost & scope 3 impact of material losses)
- Composition of key waste streams currently not sustainably treated;
- What is hindering a more sustainable treatment?
- Organic growth / step changes / discontinuity perspectives of the main Waste flows;
- Past & Ongoing projects and ideas to optimize the valorization of main waste streams;
→ Excel summary for data sharing → Data collection process detailed here → Data collection best practices Optimization levers for waste management treatment#1: Apply the sustainable waste management hierarchy (Reduce > Reuse > Recycle > Energy > Dispose) #2: Reduce volume at the source. #3: Sort at the source. #4: Know the detailed composition & calorific value of the waste. #5: Reduce hazardness of the waste (can facilitate Waste to Energy options). #6: Be connected to the SOP Task Force on Waste. Share & learn best practices. #7: Use the Solvay Waste Bank to foster synergies within Solvay. #8: Connect with local ecosystems & external partners. Collaborate with Solvay suppliers & customers. #9: Use external Waste exchange platforms. Submit waste offers. #10: No saving at the expense of the planet. Switching from energy recovery to landfill is not an option. → Best practices examples here → Technologies and tools Roadmap definition and implementationThe roadmap is divided into 5 phases (more details here): - Data Collection
- Waste Workshops
- Consolidation of ideas in macro packages
- Prioritization and planning
- Roadmap validation
