Community & Environment

Community & Environment

The Horst Engineering Family of Companies have made many contributions to the communities in which we operate. Our companies maintain strong support for the environment and sustainable manufacturing processes. We aspire to be a Zero Waste organization and are on the journey to keep our waste out of landfills.


We strive to live by the Reduce, Reuse, Recycle methodology. We have an established recycling program for our waste streams:

  • Metals (Turnings, Chips & Solids)
  • Plastics
  • Carbide
  • Waste Oil & Coolant
  • Waste Water
  • Paper & Cardboard
  • Batteries
  • Electronics
  • Fluorescent Bulbs
  • Plastic Bags/Poly Bags
  • Food Containers (Plastic, Glass, Metal)
  • Food Waste

We work to minimize our packaging waste. We have established relationships with several recycling partners. By returning our metal turnings, chips, and solids back in to the supply chain, they are turned back in to valuable resources.

Solar Power

Horst Engineering Solar Panels

One of the more visible examples of Horst Engineering’s commitment to the environment is the two solar power electric photovoltaic (PV) systems located on the roofs of our Cedar Street plants. At 41 Cedar Street, 128 solar panels/39kW contribute more than 42,000 kWh of clean power, about 43% of the plant site’s total annual average electric demand. Real time performance of our system can be tracked through our Live System Monitoring. The solar system went live in January 2009, and was made possible  by a grant from the Connecticut Clean Energy Fund. After state and federal incentives, the expected payback on the total investment is 6-8 years.

At 36 Cedar Street, 149 solar panels/37kW contribute more than 41,000 kWh of clean power, about 7% of the plant site’s total annual average electric demand. The solar system went live in April 2015. After state, federal, and renewable energy credit (ZREC) incentives, the expected payback on the total investment is 6-8 years.

How Solar PV Electric Power Systems Work

Photovoltaic cells are made of very pure semiconductor grade silicon, the most common element in the Earth’s crust, similar to that used in computer chips.

Electricity is produced as photons of sunlight penetrate the silicon, bumping electrons into a flow. PV cells are connected together to make a module. Modules are the building blocks connected together to make an array.

The photovoltaic effect produces DC (Direct Current) electricity. This DC power is converted to AC (Alternating Current) electricity to match the American standards of AC frequency and voltage. The conversion is made by an important system component called the inverter. The array and inverter are engineered for efficiency and compatibility. The AC electricity can then be used to power your home, school or business.

Energy you don’t use is credited to you as it passes through your utility meter and into the utility grid. This is known as net-metering.

Green Building & Energy Consumption

In addition to the solar electric power system, Horst Engineering uses many best green building practices at its facilities and in its operations.


  • Split System Units with gas heat, high SEER air conditioning, and economizers
  • Internet Protocol (IP) programmable thermostats


  • Natural lighting
  • T8, T5, and LED high efficiency lighting with motion sensors


  • Walls: Rigid Foam Board and tape sealed
  • Ceiling: Fiberglass paper backed batts, reflective foil barrier, and drop ceilings

Compressed Air Systems

  • High efficiency Variable Speed Drive compressors with oversized tanks
  • Closed loop plumbing


  • Low Volatile Organic Compound (VOC) paints
  • High efficiency electric hand dryers
  • Dual flush toilets

Horst Engineering is a member of The Connecticut Green Building Council.

1% For The Planet

One percent for the planetOur thread rolling business joined 1% For The Planet in 2008. This non-profit organization, with more than 1,000 member companies was founded in 2002. 1% For The Planet has inspired members of the business community to contribute 1% of sales to environmental groups around the world. Yvon Chouinard, founder of Patagonia Inc., and Craig Mathews, owner of Blue Ribbon Flies, created 1% For The Planet to encourage more businesses to support environmental groups. The mission is “Use market forces to drive positive environmental change by inspiring companies to give.” Membership demonstrates that the Horst Engineering cares about sustainable business practices.

Environmental & Conservation Organizations

Additionally, many of our employees are hikers, cyclists, trail runners, fisherman, hunters, and other lovers of the environment. Some of the conservation, outdoors, and environmental organizations that have received support are:

Community & Social Organizations

Horst Engineering has supported many community organizations during its long history. Examples include annual support for the Bolton Road Race, Brian A. Aselton Memorial Snow Dash Road Race, East Hartford Childplan, and the East Hartford Community Shelter. Support has also been given to many social organizations, including International Medical Corps.

Industry Associations

Horst Engineering and Sterling Machine are proud members of many business and industry associations:
