The two constituents space augmentation used in various engineering applications to increase the and a matrix. The most blessings of composite strength and to optimize the weight and the cost of the materials square measure their high strength and product. In this project banana fiber and coconut stiffness, combined with density, in comparison with sheath fiber are taken for the development of the bulk materials, letting a weight reduction within the composite material. The sodium hydroxide treated banana fiber and coconut sheath fiber is used as finished half. reinforcing material for Vinyl ester resin matrix. The reinforcing section provides the strength and Composites are formed by combining materials stiffness. In determined, the reinforcement solider, together to form an overall structure that is better than and stiffer than the matrix. The strengthening is the individual components. The two materials work commonly a fiber or a particulate. together to give the composite unique properties.

    POST HARVEST PROFILE OF BANANA: 2015 GOVERNMENT OF INDIA MINISTRY OF AGRICULTURE (DEPARTMENT OF AGRICULTURE & COOPERATION) DIRECTORATE OF MARKETING & INSPECTION BRANCH HEAD OFFICE NAGPUR MRIN P R E F A C E Banana (Musa sapientum) is an important fruit crop in India. Bananas are grown in more than 150 countries, producing 105 million tonnes of fruit per year. The global production of banana is around 102028.17 thousand tons of which India contributes 29.19%. Main banana growing states are Tamil Nadu, Maharashtra, Gujarat, Andhra Pradesh and Karnataka. The Inter-Ministerial Task Force on Agricultural Marketing Reforms (May, 2002), suggested several measures for strengthening agricultural marketing system in the country for benefiting the farming community to enhance the share of farmers in the ultimate price of their produce as well as for various market functionaries in the new liberalized global market opportunities and to foster true competition among the market players. This profile has been prepared on the recommendation of the Inter-Ministerial Task Force with a view to enable the farming community to scientifically manage the post-harvest operations and to widening awareness for better marketing of the bananas. The profile covers almost all aspects of the marketing, such as post-harvest management, marketing practices, quality standards, grading, packaging, transportation, storage, SPS requirements, marketing problems, marketing information, etc. This “Post-Harvest Profile of Banana” has been prepared by Shri Akshay Yakub, Senior Marketing Officer under the supervision of Shri C R Jena, Deputy Agricultural Marketing Adviser and assisted by Ms. Aparajita Ghosh, Junior Statistical Officer, Directorate of Marketing and Inspection, Branch Head Office, Nagpur.

    Use of LCA and design to study sustainable alternatives to plastic takeaway cutlery and crockery ANIRUDH MURALIDHARAN GAUTAM Outubro de 2017 Use of LCA and design to study sustainable alternatives to plastic takeaway cutlery and crockery Anirudh Muralidharn Gautam Dissertation submitted for graduation in the Masters in Sustainable Energies Instituto Superior de Engenharia do Porto Department of Mechanical Engineering outubro de 2017 Master thesis for the completion of the second year of the Masters in Sustainable Energies Candidate: Anirudh Muralidharan Gautam, Nº1150077, [email protected] Academic supervisor: Nídia Caetano Co Supervisor: António Augusto Areosa Martins Masters in Sustainable Energies Department of Mechanical Engineering outubro de 2017 Abstract 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.

E-mail: [email protected] 2Assistant Professor, Department of Mechanical Engineering, Adithya Institute of Technology, India. E-mail: [email protected] Article Received: 23 February 2017 Article Accepted: 06 March 2017 Article Published: 11 March 2017 ABSTRACT In present scenario natural fibers have received much attention because of their light weight, nonabrasive, combustible, nontoxic, low cost and biodegradable properties. Among the various natural fibers, banana fiber was focused for its pretreatment conditions for preparing perfect fiber. In previously many researchers have found various fibers have been pretreated and they obtain its properties and its applications. In this project banana fiber has been taken as natural fiber and it was pretreated and its properties after pretreatment were obtained. The pretreatment was alkali, sodium hydroxide, potassium permanganate treatment, and bleaching was carried out. Then the composite specimen boards were fabricated by various pretreatment banana fiber, polyethylene and matrix. It undergone to mechanical testing, tensile test, hardness test and also SEM analysis was carried out to check their microstructure. The perfect fiber was found by the obtained results from their properties and bonding nature. Keywords: Natural fiber, Filler materials, Resin, Pretreatment and Reinforcement. 1. INTRODUCTION With increasing numbers of applications and mass volume uses, in particular, recording double-digit growth worldwide, disposal of composites after their intended life is already becoming critical, as well as expensive.

The ancient Egyptians, Greeks and Romans used a different kind of paper called `papyrus’. To-day’s kind of paper was first developed and used by China and spread to other countries. Growth of human population, need for transfer of knowledge, education and information within the society at large were forcing factors for innovations and notable increase on the production of paper. Modern paper making began in early 19th century in Europe. All most all paper is manufactured using trees as primary source of wood pulp. Paper manufacturing continues to be a concern in modern times from an environmental perspective due to its use of large number of trees, harsh chemicals, huge water consumption resulting in ecological imbalances, pollution and contamination risks.

Due to the negative effect, this paper introduces about making paper by non- wood plant. In this paper, banana fibre and pineapple fibre were used to replace wood fibre for paper making. Banana and pineapple fibre also mixed with waste paper and sugarcane bagasse in different ratios and give different analysis. The samples were analysis in their absorbency, tensile strength, bursting strength, abrasion and crease recovery. Banana fibre was used with sugarcane bagasse and wastepaper to produce paper in ratios 20:80, 40:60, 60:40 and 80:40. For pineapples was mixed with sugarcane bagasse and wastepaper in 20:80, 40:60, 60:40, 80:20 and 100:0 ratios. The analysis showed that paper mixed by 100% bagasse and banana fibre have nearly similar in absorbency which are 2.17s and 2.155s respectively. Paper from 100% banana and pineapple have least recovery angle which were 32.5˚ and 32.3˚ respectively. Paper that have lowest recovery angle have potentially uses as wrapping paper.
