Green engineering and green architecture have the same goal of minimizing environmental impacts as well as human health in order to achieve sustainable development. Sustainable development is “Development that meets the needs of the present
without compromising the ability of future generations to meet their own needs”
(Sonnemann and Margni 2015). Green engineering and green architecture have the
same goal of minimizing environmental impacts as well as human health in order
to achieve sustainable development. Sustainable development is “Development that
meets the needs of the future without compromising the ability of future generations
to meet their own needs”.

2.1 The Principle of Green Engineering
The green campus is part of green engineering and the 12 principles in green engineering can be applied to support sustainability. The sustainability assessment of
campus can utilize the UI GreenMetric World University Rankings. In GreenMetric,
there are six categories, namely Structuring and Infrastructure, Energy and Climate
Change, Waste, Water, Transportation, Education, and Research.
Waste management is one of the categories and indicators that must be met by
the university so that the sustainability of the green campus can be assessed. The
university activities and the environment in a tropical climate have made a different
type of waste. The green landscapes on a whole year in tropical climates tend to
produce more waste from the garden and leaves, so composting the waste can be a
strategic approach to deal with this climate to give more benefit to environment and
human. In addition, lifestyle plays important role in the waste management system.
The plastic usage in lives of current people has become uncontrollable and created a
waste dump in ocean and land and pollution in the air. Plastic waste is still the most
challenging problem for the environment.
The university can take important action to design a waste management system
regarding the conditions of the university and the climate where the university is
located. Every university has a different type of garbage, even though located in
the same city and climate. Campus with an open design with no fence and any
boundary will have a more diverse type of garbage compared to a campus with a
closed design. This is possible because the campus with an open design can be a
mediator of household waste disposal in the surrounding community.
The way to deal with the waste in the university area depends on the policies made
by each university. Mostly the strategy was taken by many universities still dispose
of the waste in the closed landfills or burn the waste dump. The more universities take
action in waste management, the fewer the landfills bear the amount of the dump.
Green engineering has 12 principles. The 12 principles are inherent rather than circumstantial; prevention instead of treatment; design for separation; maximize mass,
