Environmental Services

The environmental services sector includes a wide range of industries, including waste management and water utility investments. These businesses are vital and essential elements of infrastructure globally.

The solid waste management industry consists of collection, transfer and disposal services for commercial, industrial and residential customers. Highstar believes that declining landfill capacity in certain markets combined with a fragmented marketplace creates attractive acquisition opportunities.

The water sector includes water and waste water utilities, as well as related treatment and services businesses. The sector's stable cash flows, combined with its need for capital improvement and expansion, make it an attractive sector for private investment.
