The use of different kinds of plastics has greatly increased inrecent years, and the disposal of plastic waste has become amajor environmental issue. The thermal and catalytic crackingof plastic waste has been regarded as one of the most feasible
plastic recycling method at industrial scale, since used plastic
could become a valuable source of chemicals, in addition togas and liquid fuels. It is well known that an adequate choice ofpyrolysis reactor is essential, due to the low thermal
conductivity of plastics. The good performance of the conicalspouted bed reactor for the continuous thermal or catalytic pyrolysis of plastics has been verified in several works.

In the 90's, feedstock recycling of plastic wastes lived an importantdevelopment and several facilities were built. Most of them arenowadays out of service because they never were profitable andthe huge investments done were never recovered. Then, I thinkthat the future of these processes must be based on lower costs
and higher added value of the products. I guess there are threepaths to follow: taking advantage of existing facilities, adjustingthem to their new purpose; researching on new catalysts andprocesses in order to reduce opperation costs and to increase
market value of the products; and improving wastes sorting andcollecting systems to achieve a more available high quality feedstock. (Ms. Inmaculada Suarez on behalf of Ms. Laura Briones)

I am honored to be awarded with this prize. I would like to thankall the participants who showed their interest in our research, andfor the fruitful discussions during the ISFR 2011. My special thankgoes to Prof. Yoshioka as my supervisor, who supported andencouraged me. This conference gave me an inside look into
various methods of plastic recycling as a good experience andmotivation for the future. I would like to continue putting effort on
being active in the front line of this important research field,
contributing to the development in plastic recycling technology.

In China, the reuse of waste plastics waste mainly focuses onmechanical recycling. However, chemical recycling can not be
replaced for some waste plastic such as complicated plastics,
thermoseting composites, etc. Developing a technically andeconomically feasible chemical recycling process for the plastics
waste is most important. Ideally, the wastes plastic aretransformed into single component product. For example, waste
polyolefin can be converted into carbon and hydrogen, or epoxy
resin can be decomposed into several kinds of compounds, andthat is what we are doing.

I am so honored and humbled to have received this award. Thankthe ISFR scientific committee for the enjoyable and informative
conference from which we got vivid understanding on theimportance of recycle system and the current state of platics
recycle in the world. The award inspired me to work harder on mygraduate research in Dr. Kamo’s and professor Yoshikawa’s labs.
Research on environmental science and technology is definitely
meaningful to the friendly world. Best wishes to the ISFR
conference next time!
