Signal Waste & Recycling has been a pillar of Adelaide’s waste management landscape for over 35 years.
Founded in 1989 by the Bolderoff family, the company began its journey in 1975 with Mike Bolderoff’s humble scrap‑metal recycling operation across the South Australian outback. From that modest start, the business grew into a full‑service waste provider that combines deep local roots with modern, environmentally responsible practices.
What sets Signal Waste & Recycling apart is its unwavering commitment to family values, reliability and community partnership. The team is entirely local, meaning that every call is answered by someone who knows the streets of Adelaide and the specific needs of its businesses. Whether you need a single pickup or a long‑term waste contract, you’ll find a responsive, honest partner who delivers consistent service without the overhead of a distant call centre.
Signal has always championed sustainability. The company works closely with the EPA and Zero Waste SA to keep landfill volumes down while maximizing recycling streams. All equipment is sourced locally whenever possible, supporting South Australian manufacturing and keeping jobs in the region.
Through its history, the company has continually expanded its offerings, adding industrial waste bins, liquid waste services, confidential document destruction and specialised bulk rubbish removal. Each service is tailored to meet regulatory standards and business demands, ensuring compliance, safety and cost‑effectiveness.
In every project, from a single office to a large industrial plant, Signal Waste & Recycling brings the same level of care and expertise that built its reputation. The result is a trusted, dependable waste solution that helps businesses operate efficiently while contributing to a cleaner, greener Adelaide.
With a focus on partnership, transparent pricing and a one‑stop shop approach, Signal Waste & Recycling remains the go‑to provider for businesses that value reliability, local support and sustainable waste management.
