Abstract: The increasing loads of pollution generated by the discharge of variable food processing waste is creating massive eutrophication and fish kill. The current waste management of seven small and medium sized food processing plants in a semiurban area, Kafr EL-Dwar, EL-Beheira Governorate has been studied during this work. The surveyed plants include: Frozen vegetables plant, two confectioneries, and four dairy products plants. Tap water and storage water samples analysis proved that they are in compliance with the Egyptian drinking water standards. All the generated wastewater are biodegradable and there is no available treatment. Wastewater of all the surveyed plants are directed either to the nearest drains or conveyed to the sewage treatment plant. These drains are used for irrigating lands. None of the surveyed plants representatives have an idea about the laws governing wastes discharge. There are no abnormal results of the measured parameters for all the collected wastewater samples except in two of the dairy products plants [cheese and milk separator]. The results of almost all the biochemical oxygen demand, chemical oxygen demand, and most probable number of coliform are beyond the limits of law 48 for 1982 regarding discharge of liquid wastes into drains. As the cost of the conventional treatment is high, the surveyed plants are surrounded by agricultural land of clay loam soil which is best suited for growing most plants, and in sparsely populated districts, it is beneficial that the wastes of the dairy and vegetable frozen plants are to be reclaimed and used in land irrigation to grow plants not eaten raw. The amount of solid waste for all the plants is considerably small [1-35 kg/day] except in two plants of confectioneries where the amounts are [0.25 and 0.5 ton/day]. This is attributed to that the confectioneries solid waste included biscuits residues generated during production. This amount is of benefits as animal food. After subtracting these amounts, the amounts of waste will be very small [2-3 kg/day]. The daily generation rate of solid waste per employee ranged between 30 gm and 1.7 kg. None of the solid waste generated is biodegradable except the waste of the frozen vegetable plant. The current methods of solid waste disposal included dumping on banks of drains, streets and/ or any vacant area as there is no dumpsite in the area. Open incineration is resorted to as well. In order to alleviate the environmental impacts of these practices, it is advisable to allocate a suitable site in the area to be used as a dumpsite for the non-compostable solid waste. However, it is preferable to co-compost the compostable solid waste anaerobically with manure. |
