Our ESI team identified several areas for improvement in
the environmental performance of Starlight that augment
existing best practices.

Eco-Solution 1: Water Recycling for Parts Washing stain.
In the CNC workshop, we noted the washing of machine
parts stained with oil or lubricating fluids before customer
delivery (Figure 4).
The company currently follows the practice of soaping (Figure 5) and washing the parts under running tap water (Figure 6).
The wastewater is directly released into the drain. The solids are collected using a toilet sink trap, allowing smaller debris to
pass through it. This process takes place just before the water is drained and disposed of. This method consumes a significant
volume of water, and the wastewater is contaminated with oil and lubricating fluid, which can harm the environment.

The CNC machine produces about 200 to 300 pieces of parts • Impact: Highly significant; potential for large-scale water
daily. As a result, tap water is wasted during each washing conservation.
cycle.
Recommendation: To develop and implement a system
that reduces and reuses the water for washing the parts.
