Green Engineering for Waste Management System …

meet need, minimize excess; minimize material diversity; integrate local material
and energy; design for commercial “afterlife”; and renewable rather than deleting
(Anastas and Zimmerman 2007).
Those 12 principles of green engineering can be implemented in the university
area to support and optimize the sustainability of green campus programs.
The population and human necessities have increased over time. And it produced
more waste. Both residential and university areas, which have intense activities also
produce a lot of waste on a daily basis. Without a good waste management strategy, it
will result in a waste dump and problems at the residential or university area itself or
at the final waste disposal. This is certainly not in accordance with the principles of
green engineering. Regarding the 12 principles of green engineering, the university
should have a strategy in waste management to realize the sustainability of green
campus and to minimize the risk factors or potential hazards posed by waste.
The 12 principles of green engineering can be applied in the university area as
a basis or reference to minimize waste generation and support the sustainability of
green campus programs.
1. Inherent rather than circumstantial
The university (stakeholders) can act as a waste management system designer by
issuing SOPs or Regulations that deal with the problem of waste from source to
processing products. Before designing, the university must first study what inputs
to output are involved during the process. The main and supporting material for the
waste treatment process must be ensured that it does not endanger human health and
the environment. The energy needed and produced during the process must also be
free from potential hazards.
2. Prevention instead of treatment
During the waste management process, the potential for the formation of waste
can still occur. In the campus waste management system, the university can design
regulations regarding limiting the amount of waste generation from the source. For
example, the academic community as a source of waste is encouraged to reduce the
use of paper in academic activities, not to use too much plastic in the canteen area,
always to consume the food that has been ordered, etc. If the effort to reduce waste
has started from the waste source, it is expected that the potential for waste that is
formed during the waste management process can be minimized.
3. Design for separation
Garbage comes from human or natural waste and has different types or properties
of different materials. In the waste management system, the type and nature of the
waste must be known to facilitate the production process, streamline costs during the
process, and can minimize the amount of energy and supporting materials needed.
Waste sorting must be done from the source to facilitate the process and selection
of the technology used. University stakeholders who act as green engineers can set
regulations regarding the standardization of sorting waste types. Sorting types of
