Key Questions Answered

Hiyoshi started its operations as a waste treatment service in 1955 with the policy to create a symbiosis society between humans and nature. Over the years, its technology expanded from maintaining wastewater treatment to analyzing water, sewage, and air conditions. Hiyoshi famously helped recover Lake Biwa's clean water after it was damaged by red tide, earning it the reputation of an environmental guardian.

Hiyoshi's CEO Tadashi Suzuki notes that India's awareness of environmental protection is rising dynamically alongside its economic growth.
