1 Introduction: Organic Waste Management
in Educational Institutions
A proper solid waste management is one of the main actions that must be implemented to guarantee the sustainability in organizations. The organic waste management is becoming increasingly urgent, as the water-food-energy link is central to
sustainable development. In this context, the International Solid Waste Association
recommends implementing practices towards organic waste minimization, acting
locally, and avoiding the disposal of waste in landfills (ISWA 2009). This alternative
does not promote the waste reuse and requires a large amount of area that can be
destined for other purposes, besides generating greenhouse gases (GHG), up to 11%
of total emissions GHG in the world.
The vision presented earlier is also used in various environmental policies around
the world. The solid waste policy of the European Union, as set out in the Brazilian
National Solid Waste Policy (Brazil 2010), states that in the management of solid
waste, priority should be given to non-generation, reduction, reuse, recycling and
waste treatment, in this order of importance. Finally, if there are no ways of adding
value to the waste, the final disposal will be made, with proper execution of environmental controls (Brazil 2010; Juras 2005). Brazilian policy considers that for the
management of organic waste, recycling and treatment should be carried out using
appropriate techniques such as composting and anaerobic digestion (Brazil 2010).
Composting promotes the decomposition of organic matter using aerobic microorganisms and this results in a stable compound, rich in humic substances, that can
be used as soil correction not only in agriculture and in public gardens, but also in
residences (Epstein 1997). Haug (1993) states that the organic compound provides
the nutrients required for a good development of the plants, increases their resistance
to diseases, and ward off possible pathogens.
The composting technique can be performed on a variety of scales, from domestic
to industrial. It has low cost compared to other technologies and has been increasingly used in environmental education projects due to its simplicity of application
in schools, companies, institutions or in residences, alongside with the possibility of
using the compound in green areas already existing in these same places (Paz et al.
2017).
One of the main difficulties with the proper management of organic solid wastes
is the alternative often mixed with other types of waste, thus making it infeasible
for both organic and recyclable waste such as plastics, paper and metals. Therefore,
