Production processes can impact the environment through atmospheric immissions, water pollution or a high level of waste generation. To protect the general public from these impacts, numerous legal and administrative regulations as well as technical standards have been issued.
Examples for ecological processes in luminaire manufacturing:
Solvents are necessary to degrease and clean metal components. These solvents are recycled in a closed loop with fully automatic filter systems and fed back into the cleaning process.
The oil sludge generated from degreasing sheet steel is retained in separators. The residue is disposed of separately from other sorts of waste.
Paints are applied using solvent-free powder coating.
Drinking water is produced at great effort in communal sewage treatment plants. Water demand is significantly reduced through cooling systems with closed loops.
Plastic waste from plastic luminaire cover (diffuser) manufacturing is recycled. Milling the waste yields granulate, which in turn is reworked into sheet material using extrusion and then fed back into the manufacturing process.
Water boilers with waste gas heat utilisation and automatic, pressure-dependent and speed-actuated circulating pumps lead to significant energy savings.
