The complex process of being a celebrity is something that no one can predict. It is the variable, occasionally irregular and totally impulsive, result of a continuous negotiation of values and meanings between the audience, the market and the celebrity.
To survive the flowing time and the constant rise of new celebrities, then, a celebrity needs an audience by which to be adored2, which means that the celebrity will be incessantly validated by the audience’s appropriation of the celebrity.

The issues of degradation, desecration and decelebrification are an integral part of the complex phenomenon of celebrity. Unsurprisingly the switch between steps related to consecration and degradation in celebrity life is a constant: the rise and fall narrative, a central component of star and fan identification streams, and media marketing.

Degradation of post-consumer PLA to lactic acid was analysed in order to assess the economic feasibility of the PLA chemical recycling process. Hydrolysis of PLA, in batch reactor, was analysed in the temperature range of 443-473K, under autogenous pressure and a constant PLA to water ratio (equal to approximately 0.11 by weight), without the use of a catalyst. The experimental results suggest that the complete degradation of PLA can be obtained using relatively low reaction-times with the production of a mixture containing the monomer and traces of the dimer of lactic acid.
