Operational Eco-efficiency and Environmental Return on Investment
To reduce avoidable environmental impacts, asset maintenance will ensure optimal operation. This, and other investments, will be monitored using Environmental Return on Investment (EROI) calculations. Besides our own businesses, we will also minimize such impacts from non-managed operations and joint ventures by engaging with our partners and stakeholders.
As a part of improving our operational eco-efficiency we are committed to reducing GHG, air emissions, and continue certifying all of our operated sites to the ISO 14001 standard to ensure standardization across all sites with regards to environmental management.
Supply Chain Management
We are now selecting contractors and suppliers based on their environmental, social and governance (ESG) performance. The ESG performance of current suppliers will be reviewed regularly and we expect to collaborate with our customers to reduce any environmental impact from logistics to support a circular economy.
Climate Change and Product Stewardship
We are committed to lowering our combined Scope 1 and Scope 2 emissions intensity by 6% by 2020 against our 2013 baseline. To support this commitment we have provided GHG inventory training to all of our relevant staff and have completed our global GHG inventory.
As a circular economy relies substantially on recycling materials, leading to less water, energy and virgin material consumption, we expect to lower GHG emissions. Environmental impacts can be minimized at each stage during the product design, manufacture, handling, and transportation steps. We are now proactively seeking out solutions to environmental challenges where GHG accounting, climate change risk mitigation and innovation become part of our strategy.
We want to manage our waste in a responsible manner and exceed regulatory requirements where possible. We have strict compliance standards in place to manage waste at sites. This includes proper waste accounting by name, type and code (as required by law), storage location, methods of off-site transportation, treatment and disposal. We record the quantity of waste generated, stored onsite and disposed of onsite and off-site, committing ourselves to waste reduction and disposal by using partners who can reuse, recover or recycle waste, thus reducing hazardous waste and ensuring that its disposal is handled by qualified vendors.
In order to grow sustainably, we use the criteria set out in our environment policy when conducting due diligence prior to mergers and acquisitions as well as when planning Greenfield expansions.
Environmental Return on Investment (EROI)
We are committed to effectively managing our environmental footprint. Every year, we invest in initiatives that have a positive environmental impact as well as cost-savings. All of our investments undergo a feasibility and financial analysis to ensure that each of our projects are sustainable. Through our Management Information System (MIS), we track our capital expenditures, operating expenditures, cost-savings and environmental impacts for all of our projects. We are continually improving our MIS and therefore improving its coverage of our plants as well as our projects.
The following are some of the major energy saving capex projects completed in 2017 that were undertaken as part of IVL’s operational excellence and to reduce GHG emissions:
- Installation of a steam turbine generator to produce electricity from waste heat recovery. The expected total energy savings is 167,235 GJ per year.
- Installation of variable frequency drives on cooling water pumps, cooling tower fans and quench air fans, with an expected power reduction of 16,560 GJ per year.
- Use of waste heat recovery for ELP generation and power generation, resulting in energy savings of 90,000 GJ per year.
- Conversion of distillation columns into azeotropes for steam reduction, resulting in energy savings of 108,000 GJ per year.
- Cabler pot seat modification, resulting in electricity savings of 35,300 GJ per year.
We also implemented other non-energy related projects such as water savings, reducing use of raw materials, chemicals, and feedstock consumption, reducing wastewater sludge disposal, and a reduction in other waste in our processes which helped in cutting emissions.
