This week on Rubbish Talk, Alasdair is joined by Aaron McIntyre, Managing Director of AWD Environmental Ltd, to dive into the world of hazardous waste, entrepreneurship, and building a business in the waste sector.

Aaron shares his journey into waste, which began in a somewhat unexpected way. Starting out in a science role working with chemicals in a lab, he moved into hazardous waste during a period of uncertainty — and quickly realised it was an industry he genuinely enjoyed. From there, he built up extensive experience across transfer stations, treatment facilities, landfill operations and major projects, including decommissioning work and site set-ups, before eventually taking the leap to start his own company.

Now nearly three years into running AWD Environmental, Aaron explains how the business has naturally evolved into two key areas: hazardous waste services and consultancy support for other operators. What started as a cautious step into self-employment has grown steadily, supported by industry relationships and a strong technical background.

A key focus of the episode is hazardous waste — an area not often covered on the podcast. Aaron breaks down what it actually means in practice, explaining that anything with hazardous properties requires a far more controlled and regulated approach. Unlike general waste, hazardous materials can’t simply be collected and taken away — they require detailed pre-acceptance checks, documentation, and confirmed disposal routes before they even leave site. This can often come as a surprise to customers, particularly when dealing with unknown or poorly labelled materials.

Aaron also reflects on his career path, from hands-on technical roles to site management and eventually running his own business. He shares honest insights into the realities of the industry — including learning from mistakes (sometimes the hard way!) and how taking on responsibility for others fundamentally changes your approach to safety.

Looking ahead, Aaron is focused on growing the business further, with plans to expand both the operational and consultancy sides. He’s also exploring opportunities around technology and AI, looking at how systems and innovation could improve processes within the waste sector.

The episode also touches on wider industry perceptions, with Aaron highlighting the frustration around misinformation — particularly the idea that “nothing gets recycled.” Having worked on sites that do genuinely good work, he emphasises the importance of helping people better understand what the industry can and can’t do, rather than oversimplifying or misrepresenting it.

To wrap up, Aaron shares advice for those entering the sector: get involved, ask questions, and understand the “why” behind what you’re doing. Waste is far more complex than it appears, and taking the time to understand the bigger picture can make a huge difference in developing a career.

A great episode that combines technical insight, real-world experience and honest reflections on building a business in the waste sector — and a fascinating look into the often unseen world of hazardous waste.
