Waste Management
Sources of waste paper can be divided into two categories i.e.
 Internal
Sources
External
Sources
Internal sources originate directly from the paper mill. Like
most manufacturing operations, paper production also creates
waste. This waste can be re-used as an internal secondary fibre
source. This internal waste is generally termed as "BROKE"
and is normally clean and contaminant free.
External sources of waste paper come from outside the mill.
External sources can be further divided into two categories
i.e.
- Pre-consumer waste
- Post Consumer waste
Pre-consumer waste is generated from
the industry from the paper converting operations, including,
printing, cutting etc. Such waste can again be very clean and
contaminant free.
Post consumer waste is waste that can be collected from households,
supermarkets etc. This is likely to be more variable in nature
and contain more contaminants.
The most important source of waste paper is from the waste paper
merchants and the major waste paper merchants are either owned
or directly connected to the individual mills. 70% of waste
paper that is recovered is controlled by mill owned merchants
or mill's appointed agents. A merchant may frequently be a link
in a long chain between the source and the user. For example,
paper waste could be generated in small quantities from a variety
of sources, collected by a "Jua Kali" man, sold to
a local waste paper merchant, who would sort out and bale the
waste and sell to a larger merchant. This could be passed by
a number of merchants, to its ultimate user, either physically
or simply by telephone. It is a very efficient method of generating
waste paper in Kenya and so it is probable that this system
will expand further in the future. This is also a source of
livelihood and income for the Jua Ka;li sector in Kenya. The
"Jua Kali" sector is what is known as the "Informal"
sector, and it earns in cash on a daily basis to the tune of
1 million shillings. The daily requirement of waste paper in
Kenya by the various paper mills is a total of approximately
250 tons. Waste paper is collected nationally through out Kenya.
In fact waste paper is a life line for various mills in Kenya.
Without adequate supplies, a lot of mills in Kenya would come
to a grinding halt. There are paper mills who run 100% on waste
paper in Kenya, namely:-
- Chandaria Industries Ltd
- Madhupaper Kenya Ltd
- Kenya Papermills Ltd.
The other major "Traditional"
source of waste paper is the "Voluntary Sector". These
include charity collections, paper banks and kerbside collection
schemes.
I know that currently Swaminarayan Community have started a
mega drive to collect various grades of waste paper, which they
sell to the mills and the funds collected goes to kitty for
their "New Temple Project". As a matter of your interest,
the staff and members of the American Embassy and the U.S. Peace
Corps collect waste paper and sell it to the mills. The fund
generated is used for Staff Welfare Expenses. Similar small
collection projects are done at various companies by their staff.
