Ultratech Green Program

Ultratech monitors the follow resource uses and impacts:

  • Solid waste recycling
  • Paper use
  • Industrial Waste Water discharge
  • Energy use
  • Greenhouse gases (CO2)

Waste Recycling

Waste is produced at Ultratech in a number of ways including recycled paper, office trash, packaging materials, and hazardous waste. In 2014 and 2015, Ultratech conducted internal and external assessments of waste disposal and recycling to validate our calculations of the percentage of waste that is recycled. The internal assessment was done early in the year, followed by the external assessments performed by the City of San Jose Environmental Services Department. The assessments identified previously unrecognized waste streams and provided updated waste diversion rates1 for waste bins hauled by city vendors. Waste recycling rates were determined for all identified waste streams using calculations validated by the city. Figure 1 provides four years of waste recycling rates for Ultratech’s San Jose headquarters. From these calculations, Ultratech has set a target of 80% waste recycled.

Ultratech uses paper in much the same way as most businesses. We studied paper use and determined best opportunities to reduce paper use are:

1) double sided-printing, and

2) increased use of databases and other electronic tracking methods.

In 2015, a significant process was converted to an electronic database, yielding an overall reduction in paper use for our San Jose Headquarters of 20% over 2014.

Industrial Waste Water Use

Industrial waste water is used by Ultratech for lithographic process activities, building cooling and process equipment.  In 2015, Ultratech upgraded cooling equipment that allowed for more water recycling.  The new equipment led to an overall water use reduction of over 30% from 2015 over 2013

Energy Use

Energy at Ultratech is primarily used to power the equipment that runs our clean rooms and manufacturing operations. Ultratech evaluates energy use to find opportunities for energy efficiency improvements. The best opportunities for energy efficiency gains are with equipment upgrades and replacement of existing equipment with more energy efficient models. Ultratech reviews energy ratings when upgrades and replacements are needed to identify the best choices available. We track the energy efficiency gains when upgrades and replacements are made.

<>Greenhouse Gas (CO2) Production

Greenhouse gases (carbon dioxide) are a by-product of electric power generation. Our energy providers supply greenhouse gas emission rates for the power they generate. Ultratech calculates carbon dioxide (CO2) produced directly from our energy use numbers. As our power use becomes more efficient, greenhouse gas emissions decrease.
