Established 15 years ago in Vietnam, Vietstar is the project owner of an integrated solid waste treatment facility and a large-scale waste-to-energy plant in Cu Chi, dedicated to processing millions of tons of municipal waste for the residents of Ho Chi Minh City. Vietstar operates as a subsidiary of the Lemna Group, a US-based corporation founded in 1983 in Minnesota. Also established by Viet Ngo, the Lemna Group specializes in environmental tech solutions, wastewater treatment, macro-infrastructure management, and solid waste recycling. With a portfolio exceeding 600 state- and national-level environmental, water, and air restoration projects across 25 countries, the Lemna Group allocates substantial capital through Vietstar in Vietnam, remaining steadfast in its mission to enhance human quality of life and safeguard the planet.

Inside the waste treatment plant
Vietstar collaborates with planetBLU⬛ as an operational execution partner, providing scientific data, raw materials, domain expertise, and artwork fabrication capabilities.

Machines that have been operating at the factory for over 15 years.
In its foundational years, planetBLU⬛’s activities centered on generating artworks directly from Vietstar’s operational processes and waste streams. This gives rise to monumental works whose scale echoes the massive machinery within Vietstar’s facilities. Furthermore, the conceptual framework of duality and equivalence is robustly articulated here: artistic creations and engineering artifacts are posited as fundamentally identical, sharing a common origin and lineage. One iteration emphasizes the mechanical imperative, while the other foregrounds its artistic dimension.
