Abstract/ Executive Summary:

The study reflects the present status of biological waste management of 35 shrimp processing industries out of 43 in Khulna district. A total of 367 MT of shrimp was purchased in the selected thirty five plants in a day which produce 135.2 MT of waste product during processing. About 80% plants discharged waste in the river and about 91.42% of the processing plants treated the waste water before discharge. Results revealed that about 80% of the plants sold their waste product. The ratio of total number of employee engaged in waste management was found male: female 1.73:1. It was found that the buyer sold head of golda for human consumption and head of bagda were used mainly in fish culture pond. The people (48.57%) consumed golda’s head was cooked in “Dip-oil-fry”. Positive and negative effects were also assessed to use waste material as alternative feed for fish. Results revealed that most of the plants (62.85%) had no future plan of waste management; while the rest plants (37.14%) had a plan to produce fish meal, poultry feed and fertilizer from shrimp waste materials. However, the shrimp processing waste offers an excellent source of protein replacement in shrimp feed formulation.

Keywords: Shrimp, Processing, Waste Management.

Location: Industries in Khulna, Khulna district

Start Date: 00-01-2006

End Date: 00-12-2006

Program Area: Resource Development and Management

Commodity: Shrimp

Objectives:

1. To obtaining some knowledge about their waste management system and to provide some guidelines which would be economically acceptable by utilizing this waste in fishmeal production which reduce shrimp production cost down to a sustainable level through waste reclamation.

Methodology:

The study was conducted among thirty five shrimp processing industries randomly selected out of a total forty three industries in Khulna. Khulna district has the great potential of shrimp culture, processing and thus waste delivered. Among total lincensed processing plants in Bangladesh, about 80% are situated in this region.Therefore the waste sample were collected from this region. The data was collected by using structured questionnaire interviews. The director and managers of the industries were interviewed to know the overall waste management system of the industries. The amount of the waste production and their system of utilizing and management of those waste in different industries were noted during personal visit to each of the industries. Data collected from one industry was cross-checked with those collected from other industries to rule out and/or solve any inconsistency in the data through follow-up visits. All the collected information from the different processing industries were accumulated and analyzed by MS Excel. The data were then presented in graphs, figures and tables.
