Source segregation, also referred to as primary segregation, is the practice of separating different types of waste at the point where it is generated, such as in households, commercial establishments, or other institutions. This means that waste generators themselves classify and store their waste according to its nature—for instance, into at least organic and inorganic components—before it is collected.
The main aim of solid waste
management practice in many areas is to segregate waste at the source.
For example, households might be asked to separate their waste into recyclable
and organic streams. This practice is considered the fundamental first step
for effective and sustainable waste management.
Key characteristics and
implications of source segregation include:
- Reduced Contamination: Waste segregated at
the source is least likely to be contaminated with other waste
types, making it cleaner and more suitable for subsequent processing.
- Improved Suitability for Recycling and Reuse:
It is crucial for material recovery and recycling, as mixed waste
often becomes too contaminated for these processes. For instance, if
organic waste mixes with recyclables, the latter becomes hard to segregate
and reuse.
- Economic Benefits: Segregated waste is more
attractive to recyclers and reduces the cost of pre-treatment before
recycling or repurposing materials.
- Legal Mandate: In many regions, including
Nepal, waste segregation at source is mandated by law. Waste
generators are typically required to store segregated waste until
collection.
