Waste Management

Reducing waste in production can be done through various methods such as using raw materials efficiently, recycling waste, reusing scrap materials, or improving production processes to minimize excess material use.
One simple way is to implement strict quality control to avoid defects and wastage.
Recycling and reusing by-products can also greatly reduce waste output.

(a) Construction: 1. Green Building Designer
2. Energy Efficiency Consultant
These roles focus on sustainable construction practices, using eco-friendly materials and designs to reduce environmental impact.
(b) Renewable energy:
1. Solar Panel Technician
2. Wind Turbine Engineer
These jobs help produce clean energy by installing, maintaining, and innovating renewable power systems.
Green jobs help protect the environment while creating employment in sustainable industries.

To minimize defective pieces in a factory, the manager must strengthen quality control at each stage of production.
This can be done by setting up inspection checkpoints to detect defects early.
Proper training for workers to handle machines correctly and follow standard procedures also reduces errors.
Using better raw materials and maintaining machinery regularly ensures consistent product quality.
Implementing strict supervision and statistical quality control techniques helps in identifying recurring faults.
Together, these steps reduce waste and improve overall efficiency in the factory.
