Its customers include the Municipality of Amsterdam, the Municipality of Groningen, Saver, and Rens Recycling — a mix of municipalities, publicly owned waste collectors, and commercial operators.
What's the endgame? Main and 21south plan to focus on product innovation, international expansion, and delivering more value to existing and new customers. Selective acquisitions may complement that growth.
