Capital Investments

Are the following investments justified:
(1) conversion from a high solids, baked enamel paint to TGIC polyester powder coatings; and (2) insulation of paint drying and curing ovens.

Business Benefits
For an initial investment of $289,029, DeBourgh saves $142,673 in operating costs in the first year. The discounted payback period is 4.17 years.

Why Was Project Performed?
DeBourgh Manufacturing Company is located in La Junta in Southeastern Colorado. The firm manufactures all-welded athletic and corridor lockers for schools and industry. DeBourgh has 80 employees, and its annual sales are around $6 million.

DeBourgh has an active resource management program responsible for finding ways to increase profits through pollution prevention and energy efficiency improvements. DeBourgh is a partner in the DOE Climate Wise program.

Project Description
DeBourgh has also participated in the DOE Energy Conservation/Pollution Prevention Assistance for Industry program. A 1995 assessment performed by Colorado State University (CSU) helped DeBourgh personnel identify a number of pollution prevention and energy efficiency projects that offered and increases in productivity and profit.

The project analyzed here is a combination of two recommendations from the CSU report. The report recommended that DeBourgh (1) convert from a high solids, baked enamel paint to TGIC polyester powder coatings and (2) that the paint drying and curing ovens be insulated.

Together these efforts demonstrate the effects of materials substitution and process improvements on raw materials and energy usage, waste disposal, and other operating costs. DeBourgh completed the paint conversion in February-March, 1996 and the oven insulation modification in April, 1996. Both projects were financed internally.

Analysis

The powder coating system installed by DeBourgh is a feature-enhanced, custom designed, semiautomatic system with oscillating spray guns and three manual stations. The system is used for roughly 75% of DeBourgh's production (the remaining 25% of products require liquid paint). The new electrostatic system doubles DeBourgh's painting capacity and reduces the number of rejects by almost 50% with absolutely no hazardous emissions to the outside environment. The total cost of the powder coating system, including installation, delivery, associated upgrades to the fire system, and purchasing expenses, is $289,029.

The oven insulation reduces heat loss from the existing paint drying and curing ovens. Including installation, the cost is $18,340.

A variety of annual cost savings are associated with the conversion from liquid (solvent-based) paint to powder paint. First-although the costs per unit of powder paint and liquid paint are similar-less powder paint is wasted because it has a higher transfer efficiency, thus less is purchased. Powder paint's higher transfer efficiency also allows DeBourgh to replace the paint booth air filters less often. DeBourgh expects no change in raw material storage costs or in paint equipment electricity use.

Powder paint equipment can be cleaned with compressed air, so DeBourgh reduces its purchases of xylene, which is used as a cleaning solvent for the liquid paint equipment. DeBourgh has an in-house solvent recycling unit that allows xylene to be reused, but the recycling process produces a hazardous sludge waste. This waste is regulated under RCRA, and is expensive to dispose. The reduction in solvent use allows DeBourgh to save on these disposal costs, regulatory paperwork, storage, and liability -- as well as on the electricity and labor required by the recycling unit.

Other labor cost savings result from increased painting automation and reduced paint booth cleanup. Worker health and productivity should also improve, because there will be fewer hazardous air emissions from the liquid paint and cleaning solvent (powder paint has no air emissions). In addition, the reduction in air emissions allows DeBourgh to save on annual air emissions fees, air quality monitoring, regulatory paperwork, and plant air ventilation (which includes heating the make-up air).

In total, DeBourgh is able to quantify $132,463 of savings associated with the powder coating system. However, this figure does not include unquantified savings such as improved throughput, quality, and productivity; reduced liability, storage costs, and regulatory paperwork; and reduced worker exposure to VOC emissions. The oven insulation reduces DeBourgh's reliance on natural gas by $10,210 annually.

Financial Parameters
The analysis uses a project lifetime of 10 years, real cost of capital of 9%, a net tax rate of 39%. Capital costs are depreciated over 10 years using the straight line method.

Financial Results
The 10-year NPV is $264,865; the 10-year IRR is 26.8%; the discounted payback period is 4.17 years.
