Werit reduces CO2 emissions through LED conversion

Werit Kunststoffwerke recently converted the old lighting technology to modern LED lighting from LED Technics Germany, which consumes around 70 per cent less electricity. The refurbishment was subsidised with a government grant for efficient buildings.

Werit Kunststoffwerke recently converted the old lighting technology to modern LED lighting from LED Technics Germany, which consumes around 70 per cent less electricity. The refurbishment was subsidised with a government grant for efficient buildings.

Werit Kunststoffwerke produces industrial packaging such as IBC containers, canisters, reusable transport packaging, plastic pallets and industrial and heating oil tanks at six locations in Europe, including the headquarters in Altenkirchen, Buchholz and Ottendorf-Okrilla.

Almost all products are reusable and can be brought into the second or third cycle through reconditioning or recycling. In general, there is hardly any plastic waste in the company; a large proportion of the recycled containers are ground, mixed in and reused.

„We have been DIN ISO 50001-certified since 2014 and have been continuously optimising our resource and energy efficiency ever since. Our most important key figure here is the Specific energy consumption per kilogramme of plastic processed (kWh/kg PE). We have reduced this value by 12.5 per cent in seven years, saving 9.2 gigawatt hours of electricity at the main plant in Altenkirchen alone.“

Starting points for power guzzlers

Werit initially invested in the areas that offered the greatest savings potential, such as compressed air generation. Finally, in 2021, an injection moulding machine and the pumps in the cold water system were replaced, an assembly machine was refurbished and now the lighting in the production halls has been converted to an LED system. The contract for this was awarded to the Cologne-based company LED Technics Germany received, which develops its own LED lights and systems with the aim of making the energy transition simple and affordable for SMEs. to make

„With the light burning for a good 6,000 hours in three-shift operation, there was great potential for savings here. This was also demonstrated by the lighting design and the profitability calculation that LED Technics Germany (LTG) presented to us during the tender process.“

The existing The supporting devices of the old luminaires could be completely reused. and the new LED strip lights and high bay spotlights were therefore quick to install.

256 old T8 luminaires were finally dismantled by LED Technics Germany and replaced with 86 new LED strip lights. Integrated daylight and presence sensors optimise energy consumption of the LED lights by a further 20 per cent. Despite a lower number of luminaires overall, the illumination is now significantly better, with 350 lux throughout the assembly area. The annual energy requirement has also improved significantly.

Rapid amortisation plus subsidy

For the energy efficiency measures at the main plant, Werit took part in a cross-industry funding programme of the Investment and Structure Rhineland-Palatinate which subsidises investments in measures to increase energy and/or resource efficiency by up to 25 per cent and sets fixed targets for CO2-savings.

For the LED conversion of the plants in Buchholz and Ottendorf, on the other hand Werit the Federal government subsidy for energy-efficient buildings (BEG).
