Niveau: Supérieur, Doctorat, Bac+8
Waste - 1 Invention and transfer of waste-to-energy technologies, 1978 – 2003 This note is a technical annex to a general report on Invention and Transfer of Climate Change Mitigation Technologies on a Global Scale: A Study Drawing on Patent Data. The complete report can be downloaded at: The note describes the invention and transfer of waste-to-energy technologies in the world between 1978 and 2003. These technologies include solid fuels based on waste; recuperation of heat from waste incineration; production of energy from waste or waste gases; and recuperation of waste heat from exhaust gases. The first section focuses on the number of inventions and gives descriptive statistics on the main inventor countries. Section 2 deals specifically with the international flows of technologies and investigates which countries are the main exporters and importers of waste- to-energy technology. Key points • The number of annual inventions in the waste-to-energy field has grown at a remarkably fast rate in recent years, with the most recent data indicating over 1,100 inventions per year. This is a very dynamic field. • Japan is far and away the most important source of inventions, responsible for approximately two-thirds of all inventions in the 1998-2003 period. • It is a relatively ‘globalised' field, with protection sought in more than one country for 20%-30% of inventions.

Invention and transfer of wastetoenergy technologies, 1978 – 2003This note is a technical annex to a general report onInvention and Transfer of Climate Change Mitigation Technologies on a Global Scale: A Study Drawing on Patent Data. The complete report can be downloaded at: http://www.cerna.ensmp.fr/index.php?option=com_content&task=view&id=192&Itemid=288The note describes the invention and transfer of wastetoenergy technologies in the world between 1978 and 2003. These technologies include solid fuels based on waste; recuperation of heat from waste incineration; production of energy from waste or waste gases; and recuperation of waste heat from exhaust gases. The first section focuses on the number of inventions and gives descriptive statistics on the main inventor countries. Section 2 deals specifically with the international flows of technologies and investigates which countries are the main exporters and importers of waste toenergy technology. Key points The number of annual inventions in the wastetoenergy field has grown at a remarkably fast rate in recent years, with the most recent data indicating over 1,100 inventions per year. This is a very dynamic field. Japan is far and away the most important source of inventions, responsible for approximately twothirds of all inventions in the 19982003 period. It is a relatively ‘globalised’ field, with protection sought in more than one country for 20%30% of inventions. The average number of countries in which a given innovation is patented is relatively stable. Depending on the year, an invention is filed in 1.5 to 2.1 countries on average. Despite increased activity in recent years, emerging economies remain far behind developed economies in terms of both innovation and technology transfers. In 2003, emerging countries produced only 7% of the world inventions.
