Global potential for technology that powers greenhouses with organic waste

A ground-breaking sustainable technology that enables greenhouses to increase crop productivity using power derived from their own recycled vegetable mass or external organic waste streams has become a semi-finalist in the 2017 Australian Technologies Competition (ATC).

The Enhanced Greenhousing system, developed by Melbourne sustainable technology business Enesys, can be added to an enclosed greenhouse to provide closely controlled and flexible environments that increase productivity and sustainability.

Enesys founder John Norwood said the technology enables vegetable growers to harness natural synergies that exist between the sun, vegetable growth and organic decay to grow crops day and night in summer and winter.

“Enhanced Greenhousing recycles problematic waste streams associated with organic decay – carbon dioxide and methane – to fuel power generation and heat-pumping and storage systems within greenhouses for vegetable growth,” he said.

“In warmer climates, an enhanced greenhouse can generate more energy that it consumes.”

Enhanced Greenhousing has many environmental benefits including:

  • reducing, and potentially reversing, energy consumption resulting in the conservation of natural resources and reduction of greenhouse gases
  • recycling waste organic material that would otherwise be dumped or combusted producing greenhouse gases
  • reducing the consumption of fresh water, nutrients and chemical fertilisers
  • collecting, storing and utilising excess solar energy to minimise or reverse the need for imported energy.
  • reducing or eliminating the need for pesticides, and antifungal and plant disease chemicals, due to the highly sealed and controlled environment.

Now in its seventh year, the ATC finds, mentors and develops Australia’s best technology companies with the “greatest global potential”.
The Enhanced Greenhousing system is one of 32 technologies that has been shortlisted for the ATC17 Business Accelerator, and is a semi-finalist in the Food and Agriculture Division.

According to the ATC, the semi-finalists are industry-leading innovators with the capability to become game changers.

This year’s semi-finalists have developed technology including electric vehicle charging, geo-fencing solutions for bike share, graphene materials for dam-liner monitoring, a fetal monitoring probe, wearable sensors for injury rehabilitation, and a secure online voting system.

John says Enesys is thrilled to have been recognised by the prestigious competition.

“As a semi-finalist, we now have the incredible opportunity to further develop our strategic business plans, showcase our proposals and visions to many of the key industry players, investors and partners, and pitch against some of Australia’s top technology companies for the 2017 prize,” he said.

The ATC winners will be announced at Technology Showcases in Melbourne and Sydney in October and November. For more information, visit

Enhanced Greenhousing is a highly integrated technology with many opportunities for local communities and industries. The system is ideally collocated with waste water treatment, food preparation, canneries, sources of organic waste, and consumers of low-grade heat such as residences, buildings, hospitals, industries and swimming pools.

“We are seeking technical and commercial alliance partners including existing greenhouse operators to host commercial trials,” John says.

“Other potential partners may include rotating machine and digester equipment suppliers, large developers planning sustainable communities, agricultural organisations, statutory authorities, and local government who wish to promote sustainability and local employment.”

Enesys will target existing industries, projects and sites with mutual benefits. For example, a council-owned landfill that may have already been capped, a sewerage treatment process, or green waste collection facility.

“Methane and carbon dioxide discharges may be problematic for councils but are a valuable resource for Enhanced Greenhousing,” John says.

Enesys is the ecologically sustainable technology and research & development entity of Melbourne-based Norwood Technologies Pty Ltd, which also operates The Project Office, a multi-disciplined electrical and mechanical engineering design and construction consultancy established in 1988.
