As novas roupas de plástico do imperador

Julio F. Campos Desde a invenção da baquelita em 1907, resíduos ou produtos plásticos foram jogados acumulativamente nos rios e consequentemente pelos oceanos. A consequência é a não existência uma única praia no mundo onde os resíduos de plástico não estão presentes. Após a poluição do ar, esta é provavelmente a nossa segunda pegada global. Durante mais de cem anos estamos poluindo os oceanos, mas desde que o problema dos grandes remendos de lixo no Pacífico atingiu a imprensa e as mídias sociais nos últimos anos, o problema ganhou atenção pública. Que ela tenha sido descoberta em 1988 e nós ficamos durante anos sem se importar com isso é de menor importância. A primeira tentativa de lidar com o problema e tentar remover o plástico em larga escala foi concebida por Boyan Slat em 2011, que iniciou a iniciativa de crowdfunding e ainda está na fase de teste do protótipo, ainda anos de efetiva operação 24/7 em reais condições do mar aberto. À medida ...

The emperor's new "sea plastic" clothes

Julio F. Campos Since the invention of Bakelite in 1907 plastic residues or products has being cumulatively thrown into rivers, and consequently oceans.  The consequence is that today there is not a single beach in the world where plastic debris is not present. After the air pollution, this is probably our second global presence footprint.      For over a hundred year we are polluting the oceans, but the problem of the great garbage patches in Pacific hit the press and social media in the last few years the problem gained public attention. That it was discovered back in 1988 and we stood for years without caring about it is of little concern. The first large scale attempt to deal with the problem and try to remove the plastic was conceived by Boyan Slat back in 2011, who started a crowdfunding initiative and it is s yet on prototype testing phase, still years from being 24/7 effective on real open sea conditions. Due to lack of investment. ...

The B-Side of Circular Economy

Julio F. Campos The circular economy for some years has been emerging as an alternative proposal to the current production model being embraced by a growing number of governments and companies. Its concept is to introduce into the production system feedback mechanisms similar to those existing in natural systems, eliminating the linear explore-produce-discard characteristic in favor of a structure based on reuse and recycling cycles, thus reducing both the volume of discarded waste and the of exploited natural inputs. Basic model of the structure of the Circular Economy Encompassing different initiatives, such as cradle-to-cradle , biomimetics or industrial ecology , in this scenario the environment would cease to be a mere reservoir of resources/waste, but an adjunct to the economic process, providing proposals for the development of sustainable economic solutions. However, when we have in mind the finite characteristic of our planet resources, for the circular econ...
