Sustainable Resource Based Materials in Food Packaging Design

This paper provides and understanding on the utilization of sustainable resources in food packaging. It reviews the negative impacts of plastic and current sustainable materials that are used to substitute plastic in food packaging. In order to replace plastics, many researches have been done to surmount the issue and biodegradable materials such as cellulose, plant fibres, starch based, and any bio-based material have undergone research and experiments to achieve the plastic free food packaging. Moreover, there has been strength and weaknesses in every bio-based material that need to be considered such as its polymer structure and its ability to withstand the outside properties. Different composition and structure of the polymer from this bio-based material determine the shelf life of a food when they are used as the packaging and how it can affect the food. Lesser additives of chemicals used to support the polymer is better. However, much research is still needed in discovering which bio-based material is the most suitable to use as the permanent eco-friendly food packaging design.

Uruguay's economy will avoid recession, narrowly

Subject The near-term economic outlook. Significance The statist model preferred by the governing Frente Amplio (FA) coalition clashes with the plan designed by President Tabare Vazquez and his economy and foreign ministers, Danilo Astori and Rodolfo Nin Novoa respectively, to try to attract greater inward investment. This adds to intra-coalition tensions after the defection of a centre-left legislator caused the government to lose its congressional majority. Impacts The fear of losing support may help to concentrate FA minds on smoothing over party splits. A new cellulose plant would boost economic growth but not diversification. The economy will avoid recession, but growth will not pick up strongly in the near term.

Diffusion Phenomenon of a Pollutant Flowing into a Lagoon

In this paper it is presented a mathematical model in the context of physics/transport/diffusion/dispersion about a contaminant that is a product of wood fiber cooking in a pulp cellulose plant, which is currently being thrown in a lagoon that does not have any water treatment process. The objective is improving the environmental conditions prevailing according to an environmental technology program of water treatment process required by the Government of Mexico through regulations and certifications in water treatment industries, and the prediction of the involvement of the contaminant in fishes from the Lagoon.
