GRPS sustainability coordinator Program for Growth’s January speaker

trovillionOn Monday Jan. 27, Kristen Trovillion, sustainability coordinator for Grand Rapids Public Schools, shared how she is helping to green the district as well as information for making our own homes greener—and healthier. Grand Rapids is one of two districts in the state with a dedicated sustainability department. So far, she has led GRPS in the following sustainable accomplishments:

Cleaning chemicals. A district-wide inventory found that schools were using a total of 65 cleaning chemicals, many of them toxic. That number has been reduced to six safe products that are equally effective. Kristen shared that hydrogen-peroxide based cleaners kill just as many germs as bleach—and without the dangerous side effects. Did you know that exposure to bleach impacts the respiratory system? It can bring on more asthma attacks or prolong respiratory illness.

This information will help the district see what goes into a successful garden and to better communicate with grounds staff, who sometimes inadvertently damage gardens during routine maintenance.

Composting. Kristen shared that 80% of GRPS waste is generated in the lunchrooms. Four or five schools are composting a little bit of that waste in the classroom with the help of local Grand Rapids’ compost company, Wormies, and some resident red worms. Eight schools are composting food waste, compostable lunch trays and napkins via a commercial company located in Zeeland. GRPS has to pay to have waste hauled to Zeeland. She is looking into introducing reusable trays at schools with dishwashers, but most schools are not set up for these.

Lawn chemicals. Overall, GRPS does not use toxic pesticides or herbicides and is switching over to organic lawn management. Kristen noted that they only use toxic herbicides or pesticides in urgent situations, e.g. with invasive species like poison ivy. When they are used, notices are posted on the school’s front doors and elsewhere.

Energy use and recycling. GRPS is in process of installing more energy efficient lighting and making best use of natural light, as healthy lighting supports learning. They are overhauling the current recycling system and will be introducing sorting stations to replace the current bins, which cause confusion and tend to disappear.

OKT will be including Kristen’s valuable input in its next revision of A Guide to Replication: Program for Growth, which will be tailored for use by GRPS in replicating the Program for Growth at other schools in the district.
