RESUMO:
Information on the quantities of green coconut shells produced in coastal regions is not well known, which can make it difficult to manage these frequently wasted materials, as well as the understanding that they can be included in a production process as a raw material, with various possibilities of use and income generation. Given this situation, the objective of this research is to develop a diagnosis of the potential for valorization of green coconut shells, after water consumption, in public places in municipalities on the southern and southern coast of Bahia. It is also intended to identify the future demand of the potential possibility for the recovery of the bark, providing subsidies that can be used to organize the use of this material. In this context, following the research method, consisting of five steps, it was possible to obtain the following results: (i) characterization and diagnosis of bark waste in the region; (ii) amount of bark generated per hut over the months; (iii) equivalences in fiber mass and occupied volume; (iv) bark handling logistics among merchants; environmental disposition of the shells in the visited places; (v) analysis of the availability of cooperation between entrepreneurs and researchers from universities or research centers; analysis of strengths and weaknesses and opportunities and threats (SWOT); (vi) identification of the main groups of possibilities for the application of green coconut husks in the market and a potential product for valorization – tubes for the creation of cocoa seedlings; (vii) obtaining future demand for tubes in the region through quantitative techniques for predicting time series; and (viii) the evaluation of the uncertainty of all quantitative information dealt with in the research. The main scientific contributions of this work consist, therefore, (a) in the diagnosis of the waste of green coconut shells in the region; (b) the possibilities of application of coconut shells; (c) in the demand forecasting method elaborated for time series without trends and with high variability; and (d) in assessing the uncertainty of the quantitative information obtained. Thus, the study developed can be used as a subsidy, either for replicating the research process in other types of waste allocated in any region, or for the adoption of public policies to manage these materials, or even for the encouragement and creation of an appropriate productive scenario for the management of green coconut shells in the study region, which contributes to the understanding of the potential for generating environmental, economic and social value from the use and processing of these wasted materials
