2.1Overview
Nile Perch Fisheries Ltd is one of the pioneers in processing Nile Perch from Lake
Victoria. The company is located at Nyakato industrial area in Mwanza, Tanzania.
It started its production commercially in December 1992. The company is engaged
in the processing and exporting of Lake Victoria Perch (Lates niloticus) and strives to
be one of the best factories to do so through its dedication to quality and customer
satisfaction. The company gained its approval to export products to the European
Union (EU Approval No. 208) in 1995 and has also registered its premises with the
Food and Drug Administration (FDA) of USA and with the Tanzania Food and Drug
Authority (TFDA). In 2002 the company was introduced to the Cleaner Production
concept by the Cleaner Production Centre of Tanzania (CPCT).
Resource Efficient and Cleaner Production (RECP) - Case Studies
2.2
Benefits Nile Perch fisheries Ltd started the Resource Efficient and Cleaner Production in
January 2010. Owing to the fact that fish processing consumes a lot of water and
energy, also plays a significant role in environmental pollution due to the discharge
of production wastes, hence during the first RECP in-plant assessment the company
focused mainly on production yield, water use, energy efficiency and environmental
compliance. After the first year of RECP implementation the yield increased by 1%,
water usage decreased by 10% resulted in saving of USD 11,250.
The Cleaner Production concept also helped the company to implement eco-labelling
concept for fair trading and the implementation of ISO 22000 and BRC GLOBAL
STANDARD-2005 FOR FOOD SAFETY. After two years of RECP implementation
there was a significant reduction in water usage, solid waste generation as well as
waste water. The yield increased further by 3.5 % from 44 to 47.5 percent by improved
utilization of raw material by better supervision, complete utilization of solid wastes
to saleable by-products and hence increasing their value. Nile perch has achieved
0% of solid organic wastes i.e. no solid organic waste dumped to the environment.
These strategies have resulted in annual savings of USD 506,224. The company
participated in the 2013 National and 2014 Regional RECP Awards competitions and
won in the Solid Waste Management category as first runner-up and second run-up
respectively.

Note: The absolute indicator provide a measurement of how much resource use/pollution
output has changed in absolute terms e.g. units of energy used or tons of waste generated.
A negative percentage indicates a decrease and a positive percentage indicates an increase.
The relative indicator gives a measurement of changes in resource use/pollution in relation
to production output. Resource productivity provides a measurement of how much
product output can be produced relation to resource used, from a sustainability point of
view, productivity should increase. Pollution intensity provides a measurement of how
much pollution is generated per unit of production output, from a sustainability perspective,
intensity should decrease.
2.3 RECP Profile
Note: The RECP profile provides a visual overview of resource productivity and pollution
intensity shown as change in % compared to the baseline values. Environmental performance
is improved when resource productivity increases and when pollution intensity decreases.
2.4 Areas of Improvement
Before RECP application at Nile Perch Fisheries Ltd the specific water consumption
was 12-15 m3 per ton of raw fish. Through implementation of RECP measures such
as encouraging dry cleaning, installing pressure guns in hosepipes and ball valves
in water taps, installing self-closing devices in urinals and hand washing stations
as well as ensuring overall preventive maintenance, the specific water consumption
was improved to 8-9m3 per ton of raw fish resulting in savings of USD 48,243 in 2013.,
equivalent to a reduction of 38% in water consumption and minimization of waste
water generation by 55,300 m3. Further improvement is expected with additional
implementation of other RECP measures such as installation of sensors and sub
metering all sections of the plant to improve monitoring of water use.
The effluent treatment plant was commissioned in June 2013. This treatment plant
has been consistently able to meet required standards of BOD below 30 mg/l and
COD below 60 mg/l. This has been facilitated by the fact that Cleaner production
techniques were able to bring down the initial BOD of waste water prior to treatment
at the ETP from an average of around 1000 mg/l to about 300 mg/litre. Treated
effluent is now being used for activities such as vehicle washing and gardening. The
treated waste water is also earmarked for use in toilets (flushing and in urinals),
cleaning premises and for cooling condensers. The ETP plant has generated
significant interest from regulatory bodies as well as other industries. It is one of the
few ETPs in Tanzania capable of meeting environmental standards for effluent.
The specific energy consumption rated at 100kWh per ton of fish before RECP
initiation. A number of options were identified aimed at reducing energy
consumption. RECP options so far implemented include installation of individual
switches in each department for controlling switching on/off lights, insulation of
doors for chillers, freezers and cold rooms, also installation of Compact Fluorescent
Lamps (CFL). Implementation of all these options has resulted in the reduction of
specific energy consumption.

workers.
7.2
Benefits
The Cleaner Production concept was adopted by Vicfish Ltd Bukoba since its
establishment in 2005 as a consequence of the concept being practised at its sister
plant in Mwanza. The actual implementation of the RECP programme was after the
participation in the RECP training workshop that was held in March 2011. Upon the
implementation of RECP options, the company was able to utilize the Nile Perch
to almost 99%, resulting into significant reduction in solid waste generation. This
has been possible due to the option of producing useful by-products that has led
to generation of revenue. Moreover, the RECP concept has enabled the company to
obtain annual savings of USD 87,674 in energy consumption, more than USD 59,130
in water usage, USD 28,125 in material management and reduction in BOD from 125
mg/l in 2011 to 30-40 mg/l in 2013/2014 by modifying the wastewater treatment
system to increase its efficiency. The company participated in the 2013 National
RECP Awards competition and won in the Solid Waste Management category as
second runner-up.

7.4
Areas of Improvement
Fish processing industries are mostly associated with high water usage and
energy consumption which results into high operation cost of the factory. Through
implementing RECP options like use of translucent roofing and glass blocks to have
enough illumination by natural light, use of exhaust fans that are run by wind (roto
dynamic fans), supply of water from the overhead storage tank to all over the plant by
gravity instead of using electric pumps, better insulation of cold storages, chill storages
and blast freezers, the company was able to reduce energy consumption by 20%.
Before RECP application, water consumption at the factory was ranging between
200-250m3/day. Through implementation of RECP measures such as eliminating the
use of tap water to melt the ice (just allow the ice to melt under ambient temperature),
reducing flow rate of pipes in the processing line, continuous inspection and repair
of water leakages, installation of water sensors at the visitors’ entrance, use of foot
operated valves, installation of shower roses in ablution sections, sensitization of
workers on efficient use of water through regular training, installation of metal
shutters at the offal and receiving sections to replace the water curtains and recycling
of cooling water, the water consumption was reduced to 120-150m3/day equivalent
to a reduction of 40%.
Through CPCT training, the wastewater treatment system was improved by installing
more screens and oil-water separators also a constructed wetland was added.

Approach Taken
Vicfish Ltd company Bukoba started implementing RECP programme in early
2011 after participating in the RECP training workshop conducted by the Cleaner
Production Centre of Tanzania (CPCT) on 23rd to 25th March 2011 under the Lake
Victoria Environmental Management Project Phase II (LVEMP II) being implemented
by the riparian countries.
The RECP implementation at Vicfish Ltd company-Bukoba was made a reality due
to the high commitment shown by the top management. After getting full support
from the top, a functional RECP team, led by the Quality Assurance and Eco-Label
Manager, was formed. Thereafter the company RECP policy (incorporating Corporate
Social Responsibility, among other aspects) was formulated.
7.7
Business Case
Through the implementation of RECP, Vicfish Ltd company-Bukoba has managed
to improve the company’s image and relationship with the community due to its
various cooperate social responsibility activities in place. Savings realized from
implementation of RECP options and funding from other sources have enabled the
company to play a significant role in funding community development projects which
include monthly mobile clinics to the islands communities, toilets, kindergarten and
secondary school classrooms, desks, shallow wells, upgrading fish landing sites, fish
ponds for orphans, piped water supply and construction of a public garden at the
Municipal round-about. The company has also been able to maintain its market in
Europe, U.S.A, Japan, Gulf and Hong Kong. This owes to the fact that the world
market is now looking for environmental best practices in production and ecofriendly products hence by having eco-label certification and practicing Resource
Efficient Cleaner Production, the company enjoys a good and competitive market.

Approach Taken
In order for Vicfish Limited to enhance its resource efficiency, reduce pollution load
and improve health and safety conditions, the company decided to utilize the RECP
approach following the training and technical assistance from the Cleaner Production
Centre of Tanzania (CPCT). Employees who were trained in RECP carried out a
comprehensive assessment to identify areas of improvement and proposed options
as presented in Table 8.2 above. The company participated in the National RECP
Awards competition in 2013 which was organized by the Cleaner Production Centre
of Tanzania (CPCT).
8.7
Business Case
Implementation of RECP options led to the increase of the company productivity.
Results show that the material utilization increased to almost 99% and water
productivity by 10%. In addition to the economic gains and improved environmental
performance that were achieved through the implementation of the RECP concept,
the company has also improved its image within the community through its various
Corporate Social Responsibility (CSR) activities.
