Jack & Declan O’Connor


BHSL was born out of necessity. Jack O’Connor had a 25,000 bird poultry shed on the family farm and was told by Limerick Country Council in 1998 that pollution from spreading the chicken manure on land meant the practice was to be banned. With business potentially doomed, Jack put his engineering experience to work and developed a system that could turn poultry manure to energy, technology that is the bedrock of BHSL’s business today.

Brother Declan had a business background, having worked in finance roles for companies including Kerry Group, eircom and JCDecaux. The entrepreneurial lure of joining his brother at BHSL to build a small idea into a thriving business was irresistible, and he is now Managing Director whilst Jack explores new applications for the technology as Director of Research & Development.

Both brothers live in Country Limerick. Jack is married to his New Zealand born wife Cushla with whom he has four children; Declan and his wife Kathy have three. When not working they take a strong interest in their local GAA club, and have both played hurling at county level. From a family of 10 brothers and two sisters the O’Connors are a close knit unit, and take great pride in building a global business that still has its heart in rural Limerick.
