“…However, the majority of these materials constitute at present a serious waste management problem. Biodegradable polymers have attracted special attention as the plastics of the 21 st century, since they can be biologically degraded and therefore can be considered as environmental friendly materials [1][2][3] . Biodegradable polymers are by definition those that degrade as a result of the action of microorganisms and/or enzymes.…”

Biodegradable compounds of poly(ε-caprolactone) (PCL)/ cotton linter were melting mixed with filling content ranging from 1% to 5% w/w. Cotton linter is an important byproduct of textile industry; in this work it was used in raw state and after acid hydrolysis. According to the results of torque rheometry no decaying of viscosity took place during compounding, evidencing absence of breaking down in molecular weight. The thermal stability increased by 20% as observed in HDT for PCL/cotton nanolinter compounds. Adding cotton linter to PCL didn't change its crystalline character as showed by XRD; however an increase in degree of crystallinity was observed by means of DSC. From mechanical tests in tension was observed an increase in ductility of PCL, and from mechanical tests in flexion an increase in elastic modulus upon addition of cotton linter, whereas impact strength presented lower values for PCL/cotton linter and PCL/cotton nanolinter compounds. SEM images showed that PCL presents plastic fracture and cotton linter has an interlacing fibril structure with high L/D ratio, which are in agreement with matrix/fibril morphology observed for PCL/cotton linter compounds. PCL/cotton linter compounds made in this work cost less than neat PCL matrix and presented improved properties making feasible its commercial use.

“…Resultados de la comercialización de la producción de bioplástico, Philp et al (2013) demuestran las condiciones positivas del Brasil en liderar el sector. Para eso, el proceso de innovación de la producción debe ser continuo y corresponder con las necesidades del mercado, en virtud de la reducción de costos al productor y atendimiento de las necesidades de los consumidores con precios semejantes a la producción de plástico no biodegradable.…”

Bioplástico: diversificación de la industrialización de la caña de azúcar que contribuye con el medio ambientLos residuos de embalajes plásticos de origen petroquímico, durante el transcurso de la historia humana se tornaron un problema ambiental, debido a largos años que llevan para su descomposición. De esta forma, ha aumentado las investigaciones sobre la innovación de polímeros biológicos que puedan atender a las necesidades de las personas y al mismo tiempo que reduce los impactos ambientales. En el mundo, la Braskem es una empresa pionera en la producción de polímeros biológicos proveniente del bagazo de caña de azúcar, siendo utilizado en diferentes formatos con finalidades distintas. El objetivo de esta investigación es levantar las actividades de la industria sucroenergética a favor de la producción de polímero biológico. La metodología se trata de un análisis documental, de divulgación hecha por la empresa en su Website a partir de 2011, referente a proveedor de materia prima, beneficios de la producción de bioplástico, el mercado mundial del producto y la influencia en los resultados financieros de la empresa productora. Los resultados identificados retratan que a Braskem ofrece instrucciones a los proveedores, sobre la producción de materia prima que será para la producción de polímero. La lista de siete beneficios vinculados a esta producción, que puede influenciar en la decisión en adquirir este tipo de polímero. Además de eso, la Braskem informa para donde y cuales empresas adquieren sus polímeros, siendo identificadas la comercialización interna y externa en el Brasil y la influencia de la comercialización de polímeros en su ingreso neto expresado en el ingreso porcentual.Palavras-chave: Innovación; Preservación de los Recursos Naturales; El Plástico Biodegradable. Bioplastics: diversification of industrialization of cane sugar contributes to the environmentWaste plastic packaging of petrochemical origin, became in the course of human history an environmental problem because of the number of years that lead to decomposition. Thus, there is growing research on innovation biological polymers that meet the needs of individuals and at the same time reduce environmental impacts. Worldwide, Braskem is a pioneer in the production of biopolymer originating from bagasse of sugarcane, which is used in different packaging formats for different purposes. The research objective is to raise the activities of the sugarcane industry in favor of the production of biopolymer. The methodology comes from the documentary analysis of disclosures made by the company on their website from 2011, relating to: supply of raw materials, benefits of bioplastics production, markets that are marketed products worldwide and the influence of this product the financial results of the production company. The results depict identified Braskem instructs the suppliers on the production of the raw material to be used for the production of the polymer. Lists seven benefits linked to this production, which may influence the decision to a...

“…Specifically, positive sustainable development opportunities are variously attributed to enhancing: global [167], national, regional [176,181,186], local and SME scales of the bioeconomy [168,187], as well as specific bioeconomic sectors [188,189]. In additon, a spectrum of industry reporting and academic literature is now emerging around keynote organisations [166], strategies, technologies [169,175], production [190] and product [174,190] level bioeconomy initiatives.…”

Abstract:The evolving phenomenon of zero waste encompasses the theory, practice, and learning of individuals, families, businesses, communities, and government organisations, responding to perceptions of crisis and failure around conventional waste management. The diverse and growing body of international zero waste experience, can be portrayed as both, an entirely new and alternative waste management paradigm, and or, interpreted as overlapping, extending, and synergetic with a general evolution towards more sustainable waste/resource management practices. Combining the terms zero and waste provokes creative, intellectual, and pragmatic tensions, which provide a contemporary axis for necessary debate and innovation in this sphere of resource management. This commentary draws on an interdisciplinary perspective and utilises some elements of the critique of zero waste, as a lens to examine and better understand this heterogeneous global community of practice. In particular, how the concept and implementation of a zero waste goal can increase community engagement and be a catalyst for the design and management of a more circular urban metabolism and hence, more adaptive, resilient, and sustainable future (zero waste) cities.
