Chloride Salts

Clay ceramic materials exposed to a marine environment may be subjected to complete degradation due to the presence of chloride salts in the air. The exposition allows the chloride to penetrate in structural pores causing an internal expansion, which eventually split the ceramic apart. In open air, the solar radiation as well as the rain and wind contribute to accelerate the degradation process. In the present work the laboratory assisted degradation of clay ceramics incorporated with a granite residue from ornamental stone processing was evaluated by synthetic seawater aggression according to standard procedure. The amount of incorporated residues, up to 10 wt % and the ceramic firing temperature, up to 900°C, were variable conditions statistically analyzed by factorial planning. Degradation wetting-drying tests were conducted up to 6 months. The results showed that the linear shrinkage of the residue-free ceramics do not stabilize during the test period for any firing temperature. By contrast, the residue-incorporated ceramics tend to stabilize after 4 months. In addition, a decrease in water absorption and flexural strength was observed in same speciemens.

Seafood Processing

Large quantities of wastes are generated in the processing of seafood such as shellfish, crustaceans and finfish. These materials contain appreciable amounts of plant nutrients which may be useful in cropping programs. Under some conditions the waste materials can be directly applied to soil but in other situations stabilization may be necessary. The method of stabilization will influence the availability of nutrients in various cropping programs. Composting with wood can effectively stabilize the waste but the slow mineralization of organic N can limit the usefulness of the compost. Combining the waste with calcium oxide (CaO) or hydrated lime [Ca(OH)2] can produce a stable material with good nutrient availability. If application rates of various wastes are based on their nutrient content, the nutrient requirement of specific crops, and the heavy metal concentrations, then potential environmental problems associated with excess nutrient and heavy metal loadings can be minimized. Application of these materials to land can effectively supply nutrients to crops and minimize environmental damage due to inappropriate methods of disposal. Key words:Seafood waste, composting, lime stabilization, crop nutrients
