Silke Hemming: “The ultra-thin glass is so flexible that it looks like plastic film. The construction industry is also taking an interest.”

Ultra-thin glass: the way forward for the low-energy greenhouse?

Glass just 0.55 mm thick has been around for some time now. It’s on every mobile phone and tablet. It’s extremely light, strong and

Solar energy project at Sundrop Farms among Clean Energy Award finalists

The large solar project that provides Sundrop Farms Australia with energy and fresh water is nominated for the Clean Energy Council’s 2018 Innovation Award.
The use of Direct Current in greenhouse horticulture appears to be a very promising alternative. A pilot in the greenhouse horticulture sector demonstrated a positive business case for the use of Direct Current (DC) for greater durability of components, as well as cost and material savings.

Direct Current highly promising alternative in horticulture

The use of Direct Current in greenhouse horticulture appears to be a very promising alternative. A pilot in the greenhouse horticulture sector demonstrated a
HVC is currently installing a capture installation for Bio-CO2 in Alkmaar as a demo trial for the bio-energy power plant. The Bio-CO2 will be tested later this year by greenhouse growers in the far north of the province of Noord-Holland.

HVC energy supplier launches trial for capturing Bio-CO2

In the Ter Laak Orchids trial greenhouses, the researchers compare the quality of the varieties Sacramento, Donau, Jewel and Las Palmas grown with standard lighting and a dimming treatment.

Limits of dimming lights in phalaenopsis reached

Intensive lighting in winter is common in Phalaenopsis growing. A long-running Dutch research project is seeking to answer the question of whether less lighting

Online software for energy-efficient greenhouses

Hortinergy is an online software package for designing energy-efficient greenhouses by simulating energy consumption and comparing technical solutions. Energy is a major expense in
Paul and Marcel van den Broek: “The more even climate plus the longer screening can result in 10 per cent energy savings per kilo of product.”

“I get goose bumps from such evenly coloured tomatoes”

The air above an energy screen is much drier than that below it. Currently around 20 companies in The Netherlands are making use of

Trias Westland drilling platform

Trias Westland hits on virtually impermeable layer of rock

Although the 4km-deep hole drilled by Trias Westland provided a ‘wealth of data’, the extraction of sustainable heat from the Trias layer is not
Residual heat for greenhouses in Heerhugowaard

Household waste heats sweet peppers in the Alton greenhouse horticulture area

A household waste disposal company in Alkmaar (HVC Alkmaar) will be supplying the greenhouses of the NH Paprika sweet pepper farm in Heerhugowaard with
A different growing strategy is a potential key to saving energy. An important part of this is to slow down transpiration.

Slowing down crop transpiration cuts energy consumption

The focus of energy savings usually lies in technology. But the crop itself offers numerous opportunities to economise on energy consumption. Many research results
