The efficient large-scale recycling of plastic waste is of increasing interest from an ecological and economic point of view, but it represents a goal that has yet to be achieved by the recycling industry. The possibility offered by different spectroscopic sensing techniques in order to identify different plastic particles to be recycled, with particular(More)
The efficient large-scale recycling of plastic waste is of increasing interest from an ecological and economic point of view but it represents a goal that has yet to be achieved by the recycling industry. The W2Plastics project aims at a fundamental change of the present status of plastics recycling by creating a breakthrough technology for the recycling of(More)
Plastics recovery and recycling represent an important issue. Polyolefins, polyethilene (PE) and polypropylene (PP), recovery from complex waste streams is a challenging issue actually not yet efficiently solved. Furthermore, PP, high density polyethylene (HDPE) and low density polyethylene (LDPE) together are both difficult to separate and chemically(More)
The chemical and physical composition of the feldspar-quartz sand-ore differ from location to location in a given open pit mine mine and the utilisation of the raw-ore, as well as its resale value will depend on these properties. Thus. a very important aspect of the operation is to determine quickly and accurately the properties of the sand at a given(More)
The systematic identification of impurities inside secondary plastics flow streams can be considered as one of the key issues to certify and to classify waste plastics fed to recycling plants and to perform a full control of the resulting processed fractions, that have to comply with market demands on grade and purity of the recovered products when compared(More)
Olive husk (OH) quality, in respect of constituting particles characteristics (olive stones and pulp residues as result after pressing), represents an important issue. OH particles size class distribution and composition play, in fact, an important role for OH utilization as: organic amendment, bio-mass, food ingredient, plastic filler, abrasive, raw(More)
