BIODEGRADABLE

Biodegradation is a natural process by which organic chemicals in the environment are converted to simpler compounds, mineralized and redistributed through elemental cycles such as the carbon, nitrogen and sulphur cycles. Biodegradation can only occur within the biosphere as microorganisms play a central role in the biodegradation process.

Phone cases are protective shells that you attach to the back and sides of your device. These are available in a variety of forms, features, factors, and materials, but their purpose remains to help reduce any drop damage.

DEFINICIÓNES

CASES

Usability has become established as an important aspect of product design. This paper describes an investigation that was carried out to identify the importance of usability in product choice related to other product attributes. Interviews were initially carried out to identify possible attributes that contribute to product choice. Experiments were then undertaken using the methods of active information search, structured preference elicitation, ranking and interviews in order to find out what attributes were important to people when choosing an example product - mobile phones. It was found that usability is indeed important in product choice but perhaps not as much as users themselves believe. Other attributes that were found to be more important were features, aesthetics and cost. The process of product choice was found to be complex and it may be the case that people have come to expect usability in their products. Further research is needed to understand more fully the changing role of usability in product choice and to further improve the quality of the user-product relationship.

Plásticos biobasados: Son producidos a partir de la biomasa, recursos naturales renovables, tales como plantas, microorganismos o residuos. Existen 2 tipos de procesos, pero nos centraremos en el procedimiento que está basado en la extracción de plantas como lo son el maíz, soya, entre otros, este suele ser el más común apartir de este procedimiento se pueden obtener platicos como nylon, polietileno entre otros que tienen las mismas propiedades que los plásticos convencionales.

Ventajas: Este tipo de plásticos pueden ser fabricados con recursos que con un manejo adecuado no presentan escases generando una huella de carbón mucho menor

Desventaja: Su procedimiento es muy meticuloso y exigente, muchas veces hay gran consumo de agua en su proceso

Bioplsticos.
