Abstract/ Executive Summary:

The study was carried out on the present status of shrimp processing plant’s waste management in Bangladesh. A detailed survey was conducted during February to May, 2013 in order to collect some basic information on the present status of shrimp waste management at shrimp processing plants through questionnaire interview on the various parameters. Information was collected from 52 plants of Khulna, Chittagong and Cox`s bazaar region. All collected information were accumulated, analyzed and are presented in graphs, figures and tables. The study had revealed that about 671.84MT of shrimp was purchased in 52 plants in a day and from which 248.8 MT of waste product was produced during processing. The study results showed that about 80% of the plants sell their waste products and rest of the plants discharged their wastes into river (63.50%) and 91.42% of the plants treated the waste water before discharge. Based on the obtained results from this study, it could be suggested that shrimp waste can be used further in different eco-friendly ways.

Keywords: Bangladesh, Present status, Shrimp processing plant, Survey, Waste management

Location: Khulna, Chittagong and Cox`s Bazaar districts

Start Date: 00-07-2013

End Date: 00-10-2013

Program Area: Animal Health and Management

Commodity: Shrimp

Objectives:

The study intends to investigate into the present status of biological waste management in shrimp processing industries of Bangladesh with a view to obtain some knowledge about their waste management system and to provide some guidelines which would be economically acceptable by utilizing this waste.

Methodology:

The method of collecting data depends upon the nature, aim and objectives of the study. There are several methods of collecting data and information. Selection of particular method depends on many considerations such as the nature of the research problem, time constraints, availability of funds etc. Selection of study area Selection of the study area for the collection of data is based on the waste management in shrimp processing plant. Primary data collection requires selection of an area which would offer a scope to fulfill the objectives of the study. Before selecting a study area, two major factors were considered: i) What kind of data is required and ii) Overall environment of the area in which the expected data should be available. The study was conducted during July to October, 2013, among 100 shrimp (EU approved 75) processing industries randomly selected out of 52 industries in Khulna, Chittagong and Cox`s Bazaar districts. where most of the shrimp processing plant and waste processors are concentrated. Khulna, Chittagong and Cox`s Bazaar are the southern coastal city of Bangladesh. Survey design Collection of data is prerequisite for any farm management and research study. The method of collecting information depends on the purpose of the study undertaken. There are several methods of data collection. The survey method was used in the present study because it is the most appropriate method through which necessary information can be obtained within the shortest possible time and requires less expense than other methods. Preparations of questionnaire Questionnaire was prepared in accordance with the objectives set for the study. In order to get complete and reliable data, a draft survey schedule was prepared which include production and utilizing and management of those wastes in different industries. Questionnaire interviews 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 waste production and their system of utilizing and management of those wastes 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 solved any inconsistency in the data through follow-up visits. The parameters selected for data collection were: i) Identification of the main occupation of the industry owners, ii) Types of ownership and investment pattern of the industries, iii) De-heading period, de-heading place and waste production volume per day of the industries, iv) Types of water used for washing shrimp, place of discharged waste water and treated of waste water before discharger or not, v) The management system of waste of those industries, vi) The utilization of shrimp waste after receiving from the industries, vii) Major problem and their future plan about waste management. Sound recorder and digital camera At the time of interview, the processing method, sanitation and hygienic condition of processing and sample picture were taken by camera. For detail information sound recorder (mobile) was also used during data collection through interview. The primary data and information were collected in respect of operation and activities involved in smoked shrimp production systems, health and hygienic condition including socio-economic condition of smoked shrimp producers. Limitation of the study Finding slots from the director or managers of the industries from their apparently busy schedules was a problem thus several visits were required to find them available for interviews. Sometimes some of the managers were denied directly for interviews due to their lack of time. The time limit of survey was not sufficient. As well some of the interview may have a biased answer to question asked. However the survey was completed. Data analysis All the collected information from the different processing industries were accumulated and analyzed by MS Excel.

Achievement/Findings:

In general, the present status of shrimp waste processing is unscientific and unhygienic compared to other countries. The system of shrimp processing waste outside the industries areas causes a serious environmental pollution occupying a large area. The present study observed that the industries discharge their waste water to the river though they claimed that those are treated before being discharged. The industries managed the waste product only if it could be sold, otherwise they just through it anyway. Some of them were trying to use it in scientific way but the proportion was not considerable. The most utilization of those processing waste was found in the form drying and sold in china companies like Jing Ying Trading Ltd., S.H. Trading, SAT Trading, China Sea Food, Jai Jiang Anji etc. It was found that about one third of surveyed industries have a future plan for producing economically viable product in scientific and environmentally sound way. For the purpose government and non-government agencies, research organization, local administration and university should co-operate together to formulate an integrated policy to intelligently manage and utilize shrimp processing waste. It is required, not only the modern technology but also pro-active authorities to utilize the shrimp processing waste and hence improve the economic conditions of the countries, industries and people engaged in this related work. Quality and safety assurance are important elements in shrimp processing, with the finished product increasingly having to meet the market`s stringent requirements. While the shrimp processing waste offers an excellent source of protein replacement in shrimp feed formulation, to the best of the author`s knowledge, no such study has yet been undertaken to exploit this alternative. Even there has been a dearth of knowledge as to the present status of shrimp processing waste production. The present study has been a preliminary effort toward this end. Utilization of shrimp processing waste as an alternative to fish meal in shrimp diet would maintain a hygienic work area while bringing the production cost down to a sustainable level through waste reclamation. Besides, results of this study would give the way for development of a backyard industry to ensure alternative sustainable livelihood for the underprivileged workforce engaged in the non-formal sector of the shrimp industry.
