In the past, office furniture manufacturing facilities, as well as many other industries such with painting and coating operations, were significant sources of air emissions. As part of their continuous improvement focus on the environment, KI manufacturing facilities have made considerable progress in reducing the amount and toxicity of air emissions that are generated as part of their manufacturing processes. These changes have positive impacts for KI and KI's customers by:

  • Improving KI employee work environments.
  • Improving regional air quality in the areas in which the furniture manufacturing occurs.
  • Reducing potential for off-gassing and indoor air quality issues associated with the use of the final product lines as a benefit to KI's customers.
  • Reducing hazardous and toxic wastes generated at the manufacturing facilities, since solvent-based (i.e. volatile) materials commonly produce hazardous wastes.
  • Being able to focus KI staff energy and efforts to productive activities rather than the strenuous and complicated tasks of air emissions permitting, record keeping, and monitoring required when a facility is a major source of air emissions.

In general, KI manufacturing facilities have improved their air emissions by following the theme of "REDUCE, REUSE, RECYCLE". The following table identifies some of the traditional methods for KI's operations and how many KI facilities have reduced air emissions in this area. Note that air emission reductions have also achieved other environmental benefits, such as water conservation, waste reduction, etc.

Traditional Process Processes at KI Facilities Environmental Benefits
Using solvents to clean metal components prior to finishing.

- 6-stage phosphate cleaning systems for metal components (a water-based cleaning system)
- Counter-current water flow in wash systems.

- Negligible VOC and HAP emissions with water-based cleaning.
-Counter-current water flow system achieves exemplary levels of cleaning, while limiting water usage and wastewater generation.
- Limited wastewater generated from system is treated and discharged to municipal wastewater treatment systems with negligible, if any, hazardous waste generation.

Using solvent-based adhesives in chair and panel assembly.

- Water-based adhesives.
- Solid or hot-melt adhesives.

- Negligible VOC and HAP emissions from water-based and hot-melt adhesives.
- Limited, if any, hazardous waste generation.

Using solvent-based paints for metal component painting. - Electrostatic powder painting
- Spray guns chosen for transfer efficiency
- High solids paints.
-Negligible VOC and HAP emissions from powder painting
  • Limited, if any, hazardous waste generation from powder painting since materials are not hazardous.
  • Transfer efficiencies of the spray guns and the electrostatic process result in a greater percentage of paints being deposited on the intended part, thus reducing emissions and waste, and saving resources and money on raw materials.
Achieving scratch and abrasion resistance through significant coating thickness. - Paint formulations are designed for superior coverage and resistance, with minimum coating thickness. - Reduced air emissions since coating is accomplished with less paint.
Uncontrolled decorative chromium electroplating. - Dual controls on decorative chromium electroplating including a surface tension reducing agent and a dry scrubber. Per EPA's standards, a decorative chromium electroplating system needs to have one type of control device installed. KI's system have two control systems, whose combined effect reduces air emissions of chromium minimal amounts.
