SÍNTESE DE BIOPLÁSTICO UTILIZANDO A CELULOSE EXTRAÍDA DA BORRA DO CAFÉ

Considerando os diversos impactos ambientais e a grande poluição causados pelo uso e descarte dos plásticos convencionais, os integrantes do projeto propuseram o aproveitamento do resíduo da borra de café para a síntese de um bioplástico, através do método de extração da celulose da mesma e em seguida, a realização do tratamento alcalino. Assim, buscando o aproveitamento e uma destinação mais adequada para o resíduo, além de pesquisar uma alternativa mais sustentável para o problema dos plásticos. Contudo, devido a pandemia da COVID-19 e a suspensão das atividades presenciais, ainda não foi possível a realização do procedimento experimental

SÍNTESE DE BIOPLÁSTICO UTILIZANDO A CELULOSE EXTRAÍDA DA BORRA DO CAFÉ

Ao considerar o impacto ambiental causado pelo plástico no Brasil, esta pesquisa busca uma solução para contribuir com a resolução deste problema, ou seja, a obtenção de um bioplástico biodegradável utilizando o método de extração da celulose da borra do café e, posteriormente, realizando o tratamento alcalino. O café tem uma importância histórica, cultural e econômica no país e seu maior destaque ocorreu nos séculos XIX e XX períodos conhecidos como o Brasil Império e República Nova. Na etapa de produção do café tem-se a prova, a qual gera quantidades consideráveis de borra. Diante disso, no final do ano de 2019, em parceria com Torrefação e Moagem de Café Colonial resolveu-se aproveitar este resíduo, visando uma destinação adequada para o mesmo

Global economic burden of unmet surgical need for appendicitis

Background There is a substantial gap in provision of adequate surgical care in many low- and middle-income countries. This study aimed to identify the economic burden of unmet surgical need for the common condition of appendicitis. Methods Data on the incidence of appendicitis from 170 countries and two different approaches were used to estimate numbers of patients who do not receive surgery: as a fixed proportion of the total unmet surgical need per country (approach 1); and based on country income status (approach 2). Indirect costs with current levels of access and local quality, and those if quality were at the standards of high-income countries, were estimated. A human capital approach was applied, focusing on the economic burden resulting from premature death and absenteeism. Results Excess mortality was 4185 per 100 000 cases of appendicitis using approach 1 and 3448 per 100 000 using approach 2. The economic burden of continuing current levels of access and local quality was US $92 492 million using approach 1 and$73 141 million using approach 2. The economic burden of not providing surgical care to the standards of high-income countries was $95 004 million using approach 1 and$75 666 million using approach 2. The largest share of these costs resulted from premature death (97.7 per cent) and lack of access (97.0 per cent) in contrast to lack of quality. Conclusion For a comparatively non-complex emergency condition such as appendicitis, increasing access to care should be prioritized. Although improving quality of care should not be neglected, increasing provision of care at current standards could reduce societal costs substantially
