Technology, Environment and Sustainability

Reduced Pesticides

We are recognised in the salad sector as a pioneer of the use of integrated crop management principles and techniques, having introduced biological agents to reduce our usage of pesticides.

Bee

Across our grower network, we have reduced pesticide applications by over 90% in the last 15 years, and are growing without the use of pesticides where practical to do so.

Reduced Carbon Footprint

Our growers are committed to using energy in the most effective and efficient manner and we were one of the first companies in the UK to invest in the use of the Combined Heat and Power concept for local energy production.

Combined Heat & Power

Our CHP engines are owned and run by us and only used when we can use the heat and carbon dioxide to help the growing crop. This equipment enables us to operate 27% more efficiently than conventional oil heated systems.

All sites use fixed and movable energy screens to prevent heat loss and reduce our carbon footprint by 30%.

We are committed to reducing our carbon footprint year on year, by investing in technology.

Recycled Growing Materials

We have pioneered the use of Coir (coconut fibre) as a soil-less recyclable medium in all of our glasshouses.

Coir Glasshouse

This environment-friendly system has provided our growers with a re-usable substrate that not only has real and proven benefits for root growth and water retention, but at the end of its commercial life, we donate it to local farmers who incorporate it into the soil as a conditioner. This also eliminates the disposal issues associated with other growing mediums.

Recycled Water

We have water storage facilities in the form of tanks and reservoirs, to harvest all the rain that falls on to our glasshouse roofs for use on the crops growing within.

Water Recycling

We also recycle excess water from the growing media and blend it with the rain water enabling our nurseries to be 80% self-sufficient in water. We are upgrading the current reservoir in our Cambridge nursery, enabling us to store 22,000m3 of harvested rainwater. This will allow us to store all the rainfall from even the wettest winters, for use in the driest summers.

All our nurseries have a fully computerised analytical measuring system which optimises the use of stored and recycled liquid by prioritising the source ie: rainwater, borehole, recycled. The combination of recirculation, reservoir and borehole water will allow us to get closer to our goal of self-sufficiency on water.

Protecting The Environment

Stubbins are committed to protecting the environment.

All of our nurseries adopt the principles of integrated farm management (IFM) to increase biodiversity levels, and mitigate the effects of production on the environment.

Conservation

We have key habitat areas on each site, to encourage local wildlife species to increase.

Pondlife

We seek advice from local conservation experts, and communicate our environmental goals to our staff and to our customers.

Regional Freshness

The geographical spread of our production sites, enables us to meet the demand for regional food and fulfil our desire to consistently provide the freshest possible products.
