Resumo(s)
Milhares de milhões de toneladas de lixo são produzidas anualmente e consequentemente outras tantas acabam em aterros que se encontram já sobrecarregados. Esta excessiva produção de resíduos muitas vezes tóxicos, provenientes de uma atividade industrial
extremamente poluente, e uma fraca gestão de resíduos, faz com que os especialistas ambientais de todo o mundo, se questionem sobre qual será afinal o futuro do nosso planeta.
É neste mesmo conceito que se foca a presente dissertação, que visa desconstruir a
forma como os produtores olham para os seus resíduos, expandindo horizontes no sentido da
valorização e reutilização dos seus excedentes e, disseminando técnicas de Simbiose Industrial. Desta forma, é proposto um guia de valorização genérico, que ambiciona apoiar os
produtores das mais variadas indústrias a tomarem decisões para a valorização dos seus resíduos.
São propostas várias etapas distintas que pretendem debloquear as barreiras de classificação e valorização de resíduos, que serão aplicadas na avaliação de resíduos provenientes das indústrias de peixe, para futura aplicação na produção de fertilizantes biológicos,
que de forma sustentável e rentável, apresentam grandes potenciais para a fortificação nutricional dos solos.
Billions of tons of waste are produced every year and, consequently, just as many end up in landfills that are already overloaded. This excessive production of waste, often toxic, from an extremely polluting industrial activity, and a weak waste management, makes en- vironmental specialists around the world wonder what is the future of our planet. Who knows, maybe it will be possible to balance our world a little if we learn how to fill the needs of some with the excess of others, making our society and planet more circular. And it is on this same concept that the present dissertation is focused, which aims to decon- struct the way producers look at their waste, expanding horizons towards the valorization and reuse of their surplus and, disseminating techniques of Industrial Symbiosis. In this way, a generic valorization guide is proposed, which aims to support producers from the most varied industries to make decisions for the valorization of their waste. Several distinct steps are proposed that intend to break down the barriers of waste classification and valorization, which will be applied in the evaluation of waste from fish industries, for future application in the production of biological fertilizers, that in a sustainable and prof- itable way, present great potentials for the nutritional fortification of soils.
