Manufacturer of pre-finished foamed plastic trim moulding. The plastic mouldings are pre-finished alternatives to traditional wood mouldings used around windows, doors and floors.
The plant is about 250,000 square feet in size and is located in an area of farmland and scattered residential housing. The total facility property area is about 35 acres.
In 2007, this project was in the "maintenance phase". We have significantly exceeded our goal.
The net weight of the waste in the hopper used for the collection of trimmings from the lamination department is the amount of waste. It is normalized by the amount of production (annual gross lineal footage processed) through the lamination department.
Gross lineal footage processed annually by the lamination department.
This project was completed in 2005 and is now in the "maintenance" phase. The RCRA non-hazardous waste flammable solids waste stream is collected in drums and incinerated. This method of treatment is the best management practice for this waste stream as the facility does not wish to send solvent-contaminated disposables to the local landfill.
The amount of hazardous waste flammable solids generated in a year is the waste quantity. It is normalized by the amount of production (annual gross lineal footage processed) from the print department as most of this waste stream is generated by this department.

We continued to increase our energy reduction practices in the plant. We determined that we did not need to run the dehumidifier(s) in our flowcoat paint department. Lights are now turned off in areas of the plant where people are not routinely present. The light switches in many offices and rest rooms have been replaced with motion detectors. The HVAC in our print/lamination department was again adjusted to reduce heating and cooling requirements. The air handling unit for the maintenance department is turned off during 2nd and 3rd shifts. The setpoints on the thermostats on the plant's space heaters were turned down. We continued to emphasize energy reduction during our environmental training sessions.
The amount of energy used is the usage of electricity (kwh converted to MMBtu) added to the usage of natural gas (ccf converted to MMBtu). The energy usage is normalized by the amount of production in the extrusion department (annual gross lineal footage extruded) and by the number of heating/cooling degree days.

VOC reductions exceeded our goal due to three factors: we claimed a full year of VOC reduction for our largest volume paint (in 2006 we used this paint for only 1/2 the year), we eliminated the use of a surface primer on some of our paper-laminated mouldings and the production volume of our wet printed mouldings continued to decline (this process has higher VOC emissions per foot of product).
The amount of volatile organic compounds (VOCs) are tracked and reported as required by the plant's air permit. The total annual emissions of VOCs are normalized by the amount of production in the extrusion department (annual gross lineal footage extruded).
VOC emissions are fairly equally distributed between three departments: extrusion, flowcoat and print. Thus, annual gross footage of moulding extruded will be the normalizing factor.
The plant is a plastics processor (extrusion) with some finishing operations. Because this is a relatively clean industry, environmental concerns are minimal. Reaction to catastrophic events including evacuation of nearby residents are detailed in the plant's hazardous waste contingency plan. Also, potential incidents such as spills which may impact the community are listed in the plant's aspects & impacts analysis. The plant's EMS team includes members from the local community.
Environmental SOP 603 was written to insure that bulk truck transfer of solvents to/from storage tanks is performed in the safest possible manner with plant personnel present. The plant's Spill Prevention, Control & Countermeasures plan includes weekly inspection of all tanks and transformers on the property. The plant voluntarily performs an annual wastewater sampling and analysis to insure compliance with the local sewer ordinance.
The Middlebury Fire Department is given a plant tour every year. The results of the annual wastewater analysis is shared with the superintendent of the local POTW. The plant issues press releases of important environmental events for the plant. In 2007, the commissioner of IDEM visited the plant to acknowledge the plant's acceptance as charter members into the Indiana Environmental Stewardship Program. The plant environmental manager is one of two industry members of the Elkhart County Solid Waste Advisory Committee.
