The Cleantech Open's reputation is built on its clean technology Business Competition, the largest of its kind anywhere in the world. Cleantech Open alumni companies continue to score scientific breakthroughs, funding, deployments and customers.
The Global Ideas Competition, the first truly global search for exciting new clean technologies and business ideas, had entries from 31 countries in 2010. Join us in 2011 for an even bigger and better global challenge
Entries in the Air, Water & Waste category focuses on improving resource availability, conservation and pollution control. With respect to waste, the category focuses on cradle-to-cradle approaches to reduction, reuse and recycling technologies, as well as innovative business models and approaches to materials usage.
Air examples include services, instruments and equipment related to emission control, treatment or reduction technologies. Also included are creative approaches to greenhouse gas reduction, including carbon conversion and sequestration.
Water examples include treatment, storage and monitoring, recycling and conservation technologies.
Waste examples include: waste management equipment; sorting; resource recovery processes; pollution prevention, control, and treatment technology; as well as waste reduction through innovative recycling processes and new recyclable materials, such as bio-based plastics.
Example technologies include:
On-site wastewater recycling-industrial and commercial applications
Advanced water metering
Storm-water and flood control, rainwater harvesting
On-site water disinfection
Membranes for water treatment

The Energy Efficiency category comprises technology that can significantly reduce wasted energy (including natural gas), driving toward the common goal of saving the equivalent of "a power plant a year" (a/k/a "Negawatts").
Examples include advanced light sources and controls, smart / user-friendly energy management systems, energy-efficient water heaters and other appliances, high-efficiency industrial process systems, motors, pumps, and advanced space heating and cooling systems.
Example technologies include:
Pumps for water / material
Industrial process improvements
Natural gas monitoring and control (industrial or residential)
Advanced lighting controls
Waste heat management
Efficient heat transfer
Utility scale natural gas controls
Display systems for energy management
Materials use in microelectronics manufacturing
Deposition and sputtering processes
Alternatives to heat intensive processes
Glass materials production
Pure manufacture techniques for fuel cells
The Green Building category focuses on reducing the environmental impact of building construction or operation through improved design or construction practices, new or innovative use of building materials, or new hardware or software applications. Technologies are applied directly to the built environment. Technologies are applied directly to the built environment. (Building energy efficiency submissions will be considered in the Energy Efficiency category).
