Bobcats Go Green

Posted on

Waste Not is trying to help Jennell Rayos, a sustainability graduate student, with the Bobcats Go Green initiative. The group is taking on tailgate and stadium recycling at all the Texas State home games, which are as follows:

1) Saturday, 9/13

2) Saturday, 10/4

3) Tues, 10/14

4) Sat, 11/8

5) Thurs, 11/20

This Saturday (9/13) is going to be a big game and she is in need of some help!

If you’re looking for a way to get involved and help with a big project, recycling during these huge student events is a great way to get started. Volunteers are needed on Friday for set up, during two shifts on Saturday for tailgating, and a late shift for stadium recycling.

Please contact Jennell at for more info.

Community input

Posted on

Long time, no talk. Just wanted to make a post and let you know we’re still around and have some great community activities in the works. Summer is a slower time in San Marcos so hopefully you’ve been able to enjoy the river and emptier streets a bit so far.

The board is a busy group and we would love to see some input from our members and viewers.

What would you like to see Sustainable San Marcos do?

What resources should we have for you on our website?


We want San Marcos to be well equipped for sustainable practices as we face challenges of rapid growth in our community. Let us know what you have to offer!
