Introduction
This collaborative project between Stewart Engineering
Works (S) Pte Ltd and the project team from ITE College
Central explores the use of Parts Washers as an efficient and
environmentally conscious solution for cleaning machinery
components. In the context of industrial operations,
machinery is often exposed to grease, oil, and debris, which, if
not properly removed, can reduce the efficiency and lifespan
of the equipment. However, traditional cleaning methods
often involve labour-intensive processes and use solvents or
chemicals that pose risks to both the environment and worker Table 1: Resources needed before implementation of the project

impacts in areas such as pollution reduction, safer waste
management, and decreased VOC emissions. In conventional
cleaning processes, solvents are typically used to remove oil,
dirt, and grease from machine parts. These solvents, while
effective, often contain volatile organic compounds (VOCs)
that can be harmful when inhaled by workers and can lead
to environmental pollution. VOCs are a major contributor to
ground-level ozone, smog, and air quality issues that affect
human health and the environment. Improper handling and
