![]() ![]() ![]() For individual homes, industries, and other commercial centers, proper on-site storage of solid waste is the beginning of proper disposal, because unkept solid waste or simple dumps are sources of nuisance, flies, smells and other hazards. Sewage treatment plants (STP): STPs extract sewage waste from households and commercial buildings to keep citizens healthy. The individual household or businessman has responsibility for onsite storage of solid waste. It requires temporary storage of refuse on the premises. The first phase to manage solid waste is at home level. Depending on the type of collection service, handling may also be required to move the loaded containers to the collection point and to return the empty container to the point where they are stored between collections. The specific activities associated with handling waste materials at the source of generation will vary depending on the types of waste materials that are separated for reuse and recycling and the extent to which these materials are separated from the waste stream. Handling refers to activities associated with managing solid wastes until they are placed in the containers used for their storage before collection or return to drop-off and recycling centers. All rights reserved.The handling, storage and separation of solid waste at the source before they are collected is a critical step in the management of residential solid waste. Additionally, the implications of the possible presence of pollutants were discussed.Įnvironmental impact Fish by-products Risk implications Valorisation Waste treatment.Ĭopyright © 2015 Elsevier Ltd. However, a significant benefit can be achieved through valorisation of fish by-products. The obtained results showed that both valorisation process and waste management treatments presented similar impacts. According to their origin and composition, hazardous waste can be incinerated or physicochemically treated in dedicated facilities or stabilized and buried in. This comparison is a necessary step for the development and industrial implementation of these processes as the best alternative treatment for fish by-products. ![]() Possible waste disposal methods are recycling, composting, incineration, landfills, bioremediation, waste to energy, and waste minimization. In the current study, a comparative environmental assessment between a valorisation process (fishmeal and oil production) and different waste management scenarios (composting, incineration and landfilling) was developed. A waste management system is the strategy an organization uses to dispose, reduce, reuse, and prevent waste. To that purpose, there are several methodologies to evaluate the environmental impacts of processes, including those of waste management, providing different indicators which give information on relevant environmental aspects. This would help to know if the valorisation of a residue provokes higher impact than other waste management options, which means that its advantages are probably not enough for guarantying a sustainable waste reuse. However, it is important to estimate the advantages of valorisation processes not only in terms of economic income, but also considering the environmental impacts. In the same way, different added-value products can be recovered by the valorisation industries whereas fishing companies save the costs associated with the management of those wastes. Usually, fishmeal and oil processing factories collect the by-products generated by fishing port and industry processing activities, producing an economical benefit to both parts. Reuse and valorisation of fish by-products is a key process for marine resources conservation. ![]()
