Green Engineering for Waste Management System …

8. Meet the need, minimize excess
On the one hand, a waste management system or process must be designed and
adjusted to the magnitude of the needs and on the other hand, the system and process
should take into account the factors impacting the input to output. Excessive design
in a waste management system or production process will result in high costs in
capital and operational costs. The high cost of both costs leads to a lack of economic
feasibility in the waste management system or production process. And the highcost result in excessive design should be avoided in accordance with the objectives
of green engineering. In addition to minimizing costs and waste during the process,
the green engineer must design specifically and pay attention to the selected system
or process to remain in line with the users’ demand and final targets.
9. Minimize material diversity
The diversity of the material components used in the waste management system or
production process give a significant impact on the waste management system and
treatment. Components or materials used in inputs must be as low as possible in
diversity. The more diverse components in a system or process will ask the more
treatment. The diversity of components will allow more material to be wasted than
further processed. Components with low diversity in the material will be easier to be
processed by reusing or recycled into new products..
10. Integrate local material and energy flow
The design of a waste management system or production process in green engineering tries to integrate available local material with the amount of energy needed.
Integration between material and energy in the production system or process can be
carried out starting from input to output, as well as other factors, such as support and
transport facilities to the area. The availability and integration of local raw material
and energy on the site could give benefit to the system or process.
11. Design for commercial “Afterlife”
Considering the use value at the end of material and involved components is also
a strategy in the waste management system. Components involved in the system
or production process must be considered whether it can be reused or recycled to
maintain its value and usefulness. Components with high commercial value or easily
reused will reduce waste and maintain environmental health and have economic
viability.
12. Renewables rather than depleting
The renewable material and energy are better than depleted material and energy.
System design or production process must pay attention to the nature of the raw
material. The renewable raw material and energy are less damaging to the environment. In addition, waste processing technology must be renewable to overcome the
increasing quantity or even the quality of waste disposed of in line with human needs.
