William R. Sinkin Eco Centro

Eco Centro is currently closed to the public. We apologize for the inconvenience. Please sign up for our newsletter and check back on this page for updates and resources.

The William R. Sinkin Eco Centro is a community outreach center for environmental sustainability operated by San Antonio College. The Center was seed funded through a U.S. Department of Housing and Urban Development Hispanic Serving Institutions Assisting Communities grant. Currently, Eco Centro is supported by the College, through grants and donations and from partnership efforts across the region. 

The LEED-certified, 3,000+ square foot facility serves as an example of sustainable building with a solar-photovoltaic system connected to 135 roof-mounted solar panels, a 2,700-gallon water catchment tank and five 40-gallon tanks, water-wise landscaping, four electric vehicle charging stations, a B-Cycle station, and large composting and gardening areas.

Happy Earth Day! 

April 22 is Earth Day, but every day is a little bit like Earth Day at San Antonio College. We're working hard to reduce waste, save energy and water and to use greener products. We're adding pollinator habitats to our campus and giving students opportunities to learn about Green Building, Natural Resources Management and Urban Agriculture. Connect with Eco Centro on Facebook or sign up for the email newsletter to find out how you can get involved!

Here are some ways you can celebrate from home:

To cultivate the understanding, progress and practice of sustainability


Eco Centro strives to positively address environmental challenges by providing the information needed to adopt more environmentally sustainable practices.
Through education, outreach, service and research, Eco Centro advocates for the adoption of practical sustainable practices.

Our objective is to stimulate greater community, business and household self-sufficiency while supporting entities that further the overarching cause of environmental preservation through collaborative initiatives and educational programming.


The William R. Sinkin Eco Centro serves as a demonstration center for organic gardening, composting, sustainable building, low impact development, water conservation, native landscaping, healthy living, developing community partnerships and more. The center provides meeting space for several local organizations and hosts community based and environmentally-related events. By partnering with our local community, other environmental organizations, private industry, governmental agencies, and sustainability experts, the William R. Sinkin Eco Centro furthers its goals of education and advocacy on a local level and beyond.


Rapid population growth, economic expansion, and excessive consumption of our natural resources necessitates a collective solution to the depletion of those resources most basic for survival and well-being. Sustainability has emerged as that solution and is of the utmost importance in making sure we have enough water, materials, and resources to lead productive, healthy, and comfortable lives.  Each of us must do our part to conserve the natural environment on which we all depend.
