Environmentally friendly and sustainable action

Building a sustainable energy supply for a complex company - this is the challenge the KSJ is facing.
Woodchippings are produced from landscaping material (dead wood) that accumulates during daily work. We use these 3,500 cubic meters of wood chips per year to generate heat and hot water for our business premises. The sun also helps with this. Our solar thermal systems turn sunshine into heat and our photovoltaic systems generate electricity. We use intelligent charging management to power our electric vehicles, making another important contribution to climate protection.

Solar thermal energy on vehicle hall

  • with 2,700 vacuum tubes and 90 collector fields
  • with an output of 270 kW on 600 m²

This enables a 55,000 l buffer tank to be charged independently for heating and hot water preparation from May to September.

PV systems in the solar park and at the recycling center

  • with 8,432 solar modules and 107 inverters
  • Output: approx. 1,600 MWh of electricity generation in 2022

This can supply approx. 460 four-person households for a year and thus save 776 tons of CO².

In addition, further potential areas for the in-house generation of electricity at the municipal service are being investigated with the aim of making a significant contribution to conserving resources.
