In 1984, Wastech was founded to produce organic fertilisers. Within a few years, Wastech business grew to include the design, supply and installation of irrigation systems. In 1993, Wastech Engineering and Wastech Multigreen were formed, allowing each subsidiary to specialise on their markets, irrigation engineering and fertiliser manufacture respectively. In 2001, Wastech Engineering expanded internationally, setting up Wastech Engineering International in Hong Kong. In 2020, the merger of our three subsidiaries into the Wastech Group has enabled us to leverage our core competency operating in both fertiliser and irrigation engineering segments to provide end-to-end solutions to meet the needs of our customers and to also provide us with new business opportunities and growth.
