Environmental Sustainability

ADI and its employees are committed to protecting the environment and the health & safety of fellow employees, customers, and the public.

Waste


As part of our resource conservation program, we have set waste reduction goals at our manufacturing sites of 2.5% by 2020.

Recycled Non Hazardous Waste To reach our goal, ADI educates our employees on methods to reduce solid waste at home and in the workplace. We also have recycled materials programs, have comingled recycling collection, conduct audits to identify additional recyclable materials, and have paper and beverage container recycling programs. Due to expansion and growth of our Company, waste generation increased from our baseline year. Our waste (total waste generated less recycled nonhazardous waste) normalized to production, however, has shown a reduction of 1.3% from the 2015 baseline year, bringing us halfway to our reduction goal of 2.5% by 2020. Additionally, our recycling rate for non-hazardous waste has shown improvement from 60% in 2015 to 69% in 2017. We are continuously looking for ways to better our performance and are collaborating with suppliers who can help us achieve our goals. As an example, none of the waste from the Limerick campus goes to landfill, and 60% of the total waste that leaves the site goes through a recycling or reclamation disposal route. There is a constant focus on waste segregation at the source, using the color-coded waste bin system.

Responsibility with our waste production, use, and disposal continues to be a priority. In the past two years, we did not experience any significant spills in any of our manufacturing sites.

Environmental Spotlight: Hillview Sulfuric Acid Projects

Hillview uses an average of 25,000 gallons of sulfuric acid per year which is stored in encased plastic bottles.

After use, these bottles need to be triple-rinsed with water, requiring use of an estimated 70,000 gallons of water overall per year to do so. This was recognized as a significant environmental impact for the site.

In 2017, a 4,000-gallon bulk delivery tank and distribution system was installed on site, eliminating the need for the plastic bottles.

Additionally, an acid recirculation/filtration system was installed on the highest usage wet sink, markedly increasing acid bath life.

The new systems were placed online near the end of CY2017.

These projects have been essential on the journey of continuous improvement, both in the environmental and production efficiency arenas. The results include a drop in average sulfuric acid usage by 15%, 85% drop in bottle encasing usage, and a matching 85% water usage reductions, all culminating in $95k in savings thus far.
