Disclosure 103-1: Explanation of the material topic and its Boundary

Since Sika is a chemical company, stakeholders and communities close to Sika’s production sites in particular, have a great interest in how Sika manages waste and water discharge from production as they may be directly impacted through potential water contamination and improper disposal of waste.

Waste resulting from Sika’s production amounted to 74,000 tons in 2016, which represents around 1.8% of the material volume. Efficient use of input materials for production and recycling of materials resulting in a reduction of waste, is one of the key priorities for Sika. Water discharge is strongly regulated by local authorities at the Sika locations, and Sika adheres to permit limits and set standards.

As a supplier of products to the construction and transportation industry, Sika also has an impact on the waste production of its customers, through packaging material and in the after-use phase of its products. Sika sees it as its responsibility to contribute to reducing waste of its customers through better product durability, application methods, and optimization of packaging material, e.g. foil packs, mini-packs, plastic pails instead of metal, applicator tools, etc.

Disclosure 103-2: The management approach and its components

Through its management approach, Sika seeks to reduce waste resulting from production as well as products and packaging. With regard to water discharge, Sika complies with national requirements. Sika manages the disposal of waste through management systems according to ISO 14001, which are in place at all production sites.

 

COMMITMENTS

Sika strives to increase input materials efficiency in its production processes. High efficiency production in this context means reducing and reusing production scrap, reducing and reusing packaging material, and improving the packaging design, resulting in less material use, and focusing on sustainable input materials.

Sika strives to reduce effluents by controlling and reducing water inputs. Locally, effluents are managed according to their constituents, and parameters as permitted by the local authorities. For waste Sika is committed to taking back products for recycling where possible, and to increasing the durability of its products.

 

GOALS AND TARGETS

Sika’s 5-year target plan for 2014-2018 includes the following target for waste:

  • 3% less waste per ton and year

 

RESPONSIBILITIES

Effluents and waste efficiency of Sika’s operations are the responsibility of regional management reporting to the CEO. At local level, the operations manager is responsible for helping to reach Sika’s targets with regard to waste reduction, for setting, and achieving local targets accordingly, and for the compliance with local requirements for effluents.

 

SPECIFIC ACTIONS

  • Life Cycle Assessment (LCA): Sika carries out objective, transparent and comparative assessments of the sustainability of its products and systems – not only in manufacture, but throughout their life cycle in accordance with internationally recognized standards. These analyses may pinpoint potential improvements for existing products. They may also deliver important insights into resource management (raw materials, energy, water and waste) production processes or application efficiency and thereby promote innovation and optimize the development of new products and systems. 
  • Environmental management system ISO 14001: Sika production facilities are certified to ISO 14001, which allows for continuous efficiency improvement. 
  • Sustainable solutions: Sika seeks to enhance the outstanding and widely appreciated usefulness of its products by optimizing their sustainability profile, and thus to create added value for customers. 

 

Sika solutions for resource efficiency include

Disclosure 103-3: Evaluation of the management approach

Sika evaluates its management approach through:

  • Monitoring: Sika measures its effluents and waste on a regular basis. Water use is reported quarterly to the internal Environment, Health, Safety & Sustainability department where results are followed up and management approaches adapted accordingly.
  • Evaluation of results from LCA: Sika carries out life-cycle assessments (LCA) during the product development process. These serve to quantify energy demand, resource efficiency, greenhouse gas emissions, or water demand during each phase of a product’s life cycle and measure the associated possible impacts on the environment.
  • Evaluation of results from environmental management system ISO 14001: Sika production facilities are certified to ISO 14001 and perform impact assessments, target setting and management reviews of the effectiveness of the management system regarding effluents and waste.
  • Benchmarking: Sika started to compare waste generation per product unit internally through factory reporting and to benchmark with other similar companies.
  • Internal reports: The company introduced a report for the production facilities on material efficiency and consumption in 2014 and prepared another report in 2016.

 

The evaluation showed that although it is a key priority Sika did not achieve the target on waste reduction and material efficiency. Programs to reduce waste typically involve process changes which cannot be implemented in a short period. Sika will enhance the efforts in the coming year to achieve the 5-year strategic target.
