Production - is the function of the amount
and nature of agricultural waste generated by
an agricultural enterprise. The waste requires
management if the quantity produced is
sufficient enough to become a resource
concern. A complete analysis of production
includes the kind, consistency, volume,
location, and timing of the waste produced.
2. Collection - refers to the initial capture and gathering
of the waste from the point of origin or deposition to a
collection point. The method of collection, location of
the collection points, scheduling of the collection, labor
requirements, necessary equipment or structural
facilities, management and installation costs of the
components, and the impact that collection has on the
consistency of the waste should be identified.
3. Transfer - refers to the movement
and transportation of the waste
throughout the system. It includes
the transfer of the waste from the
collection point to the storage
facility, to the treatment facility, and
to the utilization site.
4. Storage - is the temporary
containment of the waste. The
storage facility of a waste
management system is the tool that
gives the manager control over the
scheduling and timing of the system
functions.
5. Treatment - is another function designed to
reduce the pollution potential or modify the
physical characteristics of the waste, such as
moisture and total solid (TS) content, to facilitate
more efficient and effective handling. Manure
treatment is comprised of physical, biological, and
chemical unit processes. It also includes activities
that are sometimes considered pretreatment,
such as the separation of solids.
6. Utilization - Utilization includes
reusing and/or recycling of waste
products. Agricultural wastes may be
used as a source of energy, bedding,
mulch, organic matter, or plant nutrients.
When properly treated, they can be
marketable.

metals, furniture and organic waste can
all be recycled.
5. Hazardous waste includes all types of
flammables, toxic, corrosive and reactive
