About the company

Sam Dennigan & Company UC was founded in 1976 by Samuel Laurence Dennigan who began trading potatoes in Oldtown, North Dublin. The company sources, assembles and distributes a full range of fresh produce to the wholesale, retail and foodservice sectors on the island of Ireland.

It is firmly embedded within the local community, giving many farm families in the area an outlet for their produce and a source of income. Solid business relationships have been forged with local suppliers through decades of mutual experience on volatile fresh produce markets and those same farm families who began trading with the company in 1976 are still doing so today.

This Irish family business is run by two brothers and directors, Joe and Sam Dennigan, and is now one of the country’s leading fresh produce companies, employing over 600 people.

Key Sustainability Commitments

Enhancing Biodiversity:

As part of their Origin Green plan, Sam Dennigan and Company UC implemented an Integrated Constructed Wetland on their site. The project aimed to optimise natural biological, chemical and physical processes of pollutant removal in a way that is compatible with local biodiversity.

Commitment to Employee Wellbeing:

In an effort to embed sustainability into the heart of their company, Sam Dennigan and Company UC have implemented an employee forum. This gives employees a platform to engage with the company's sustainability targets and make suggestions on how to improve.

Spotlight Target Area: Energy
Becoming a member of Origin Green in 2016, Sam Dennigan established an in-house
Origin Green team to set ambitious but achievable sustainability targets. Due to the
enthusiastic and steadfast commitment of this team, eleven Origin Green milestone
targets were met in 2020 with exemplary performances demonstrated in the areas of
packaging, energy, water and community engagement. Sam Dennigan acknowledges
its responsibility to the environment and to the local communities in which it works
and does business. The company actively encourages its staff to recognise those
responsibilities alongside the importance of the company’s role toward the society in
which it functions. Within the energy target area, Sam Dennigan set a target to reduce
energy usage by 37% by 2020 based on a 2014 baseline, the company exceeded its
target, having reached a 50% reduction on electricity usage per unit output compared
to the baseline year. This reduction in energy usage was supported by a rooftop solar
PV installation on its distribution centre in Oldtown, Co. Dublin.
