This thesis looks on alternatives to plastic takeaway cutlery and crockery from areca palm and coconut tree by products. Most of the take away materials used today are made of plastic that is disposed of upon single use. This presents a huge challenge in terms of waste management and pollution. It is widely known that plastic is produced from polymers generated by fossil oil that is explored from the soil and whose natural reserves are limited. Due to its nature, it takes several hundred to thousand years to decompose plastics, releasing toxic substances in the process.This work focuses on reviving the methods and knowledge that existed in the southern and central parts of the Indian subcontinent for producing sustainable goods used in everyday life, aiming to make sustainable cutlery and crockery. The materials that are under study are palm areca sheaths, coconut fibre, shells and banana fibres. A market analysis, design, life cycle analysis and deeper research on the fabrication was made.The life cycle analysis (LCA) was conducted from data obtained from the Eco invent v2 atabase. CML 2000 method was used to assess and compare the data. Existing data from the database was considered to estimate the final impact through weighted averages. The results show that the materials under study perform better than conventional plastic materials with respect to emissions and other parameters. The main impact involved in the production of the various products was found out to be transportation. When imported and produced in bulk, costs and impacts of the suggested alternatives are lower than those of the conventional products.Comparing results for cardboard and palm areca boxes for example the Global warming potential for the alternatives were 7.07E-02 compared to 11.2E-02 kg CO2 equivalent for the conventional products. Similarly, when plastic plates and palm plates were compared .46E-08 and 4.62E-09 kg CFC 11 eq were the values for ozone layer depletion. Most other results follow the same route which is a clear indication that most of our alternatives have a good environmental performance for a lower or the same price.

520 $a Esta tese analisa as alternativas de talheres plasticos para uso domestico e loucas de palmeiras areca e coqueiros por produtos. A maioria dos materiais removiveis utilizados hoje sao feitos de plastico que e descartado em uso unico. Isso representa um enorme desafio em termos de gerenciamento de residuos e poluicao. E amplamente conhecido que o plastico e produzido a partir de polimeros gerados por oleo fossil que e explorado a partir do solo e cujas reservas naturais sao limitadas. Devido a sua natureza, leva varias centenas a mil anos para decompor os plasticos, liberando substancias toxicas no processo.Este trabalho centra-se na revitalizacao dos metodos e conhecimentos que existiam nas partes do Sul e central do subcontinente indiano para a producao de bens sustentaveis utilizados no cotidiano, com o objetivo de fazer talheres e loucas sustentaveis. Os materiais que estao em estudo sao bainhas de areca de palma, fibra de coco, conchas e fibras de banana. Uma analise de mercado, design, analise do ciclo de vida e pesquisas mais profundas sobre a fabricacao foram feitas.A analise do ciclo de vida (LCA) foi realizada a partir de dados obtidos do banco de dados Eco invent v2. O metodo CML 2000 foi utilizado para avaliar e comparar os dados. Os dados existentes do banco de dados foram considerados para estimar o impacto final atraves de medias ponderadas. Os resultados mostram que os materiais em estudo sao melhores que os materiais plasticos convencionais em relacao as emissoes e outros parametros. O impacto principal envolvido na producao dos varios produtos foi considerado transporte. Quando importados e produzidos a granel, os custos e os impactos das alternativas sugeridas sao inferiores aos dos produtos convencionais.Comparando resultados para caixas de papelao e caixas de palma, por exemplo, o potencial de aquecimento global para as alternativas foi 7.07E-02 em comparacao com 11.2E-02 kg de equivalente de CO2 para os produtos convencionais. Da mesma forma, quando as placas de plastico e as placas de palma foram comparadas, 7.46E-08 e 4.62E-09 kg CFC 11 eq foram os valores para a deplecao da camada de ozonio. A maioria dos outros resultados seguem a mesma rota, o que e uma indicacao clara de que a maioria de nossas alternativas tem um bom desempenho ambiental por um preco inferior ou igual.
