Umberto Arena

University of Campania Luigi Vanvitelli




Umberto Arena, chemical engineer and Ph.D. in chemical engineering, is full professor of “Solid waste management” and of "Industrial Pollution Control Engineering" at the University of Campania Luigi Vanvitelli.

He is a member of the Editorial Board of the Waste Management journal of Elsevier and of Managing Board of the International Waste Working Group (IWWG). He is the leader of the IWWG-Task Group on Thermal Treatments.

He is also a member of a number of international committees like: the Int. Scientific Committee of the Int. Conf. on Industrial and Hazardous Waste Management; the Int. Scientific Committee of the Int. Symposium on Urban Mining; the Int. Scientific Committee of the Fluidized Bed Conversion Conference; the Int. Advisory Board of the Int. Symposium on Energy from Biomass and Waste; the Int. Expert Group on Life Cycle Analysis for Waste Management; the Int. Scientific Committee of the Engineering Foundation on Fluidization; the Int. Advisory Board of the Int. Conference on Circulating Fluidized Beds.

He is in charge of research programs with several companies and research centers. In particular, he worked or still works with Sagit-UNILEVER, Fater-P&G, CONAI (the Italian National Consortium for Packaging), ENI (Snamprogetti, Enitecnologie, Agip Carbone, Enichem Anic), ENEL, Ansaldo Energia, ENEA-Environmental Department, Eco-Bat, CIRA (the Italian National Centre for Aerospatial Research),, Eco-Engineering, ChemTex. He prepared the Solid Waste Management Planning for some Italian regions. He was also a member of the Scientific Committee for the evaluation of Environmental Risk in Campania Region.

He is author of more than 90 scientific papers published in international scientific journals and he wrote chapters for some multi-authored books, published by Chapman & Hall, J. Wiley&Sons and Woodhead Publishing.

Umberto Arena’s research and professional activity is mainly oriented to several aspects of waste management, with particular attention to:

  • thermal treatments (combustion, gasification and pyrolysis) of different fuel and wastes;
  • design and operation criteria of fluidized bed combustors and gasifiers;
  • technological, economical and environmental aspects of the different recycling and recovery routes (mechanical recycling, feedstock recycling and energy recovery) of municipal and industrial wastes;
  • application of Life Cycle Assessment, Material Flow Analysis and Substance Flow Analysis as tools for environmental assessment of waste management planning and for optimization of different waste treatments.

He co-operated in several international research programs, with a number of international partners: Technical University of Vienna-Austria; Technical University of Hamburg-Hamburg – Germany; Massachusetts Institute of Technology – MASS, USA; Technical University of Halifax, Canada; Centre for Environmental Strategies-University of Surrey, Guildford - UK); Centre for Renewable Energies, Athens – Greece; Ciemat, Spain.
