Dobbs Ferry, N.Y. – June 27, 2013– While other college students are relaxing this summer, Mercy college students are making a positive impact on the world through composting! Members of Mercy College’s club ENVISAJ (The Mercy College Environmental Sustainability and Justice Club) will be working to actively engage Town of Greenburgh residents in composting and raising awareness about bio-digester technology as part of the College’s over all mission to reduce solid waste in the community. 

The ENVISAJ students, under the supervision of Mercy College visiting faculty researcher Dr. Thomas (Taha) Rassam Culhane, are actively researching bio-digester technology and have been maintaining two bio-digesters Mercy’s Dobbs Ferry campus. Along with teaching residents about the benefits of composting and how to set up a home system, the students hope to also establish locations in the Town of Greenburgh where bio-digesters can be placed and used.    

Greenburgh Town Supervisor Paul Feiner says, “We are thrilled that Mercy College students will be leading the way --helping to change people's habits by promoting organic recycling. The students at Mercy College, working with faculty members, will be partnering with the town government on a very important initiative. They are not only learning about government but they are becoming a part of it and making a positive impact on the environment.”

Mercy College student leader, Tasheem Hall, says “Our garbage has value. Throwing away our garbage is like throwing away our money. It is time we show people there are other ways to harvest clean energy without relying on government subsidies. This is how we continue the cycle of energy that we get from sun.”

To help spread their message, the students plan on:

  • Creating a blog detailing their work on composting and bio-digesters
  • Creating a “What to Compost” brochure
  • Creating a “How to Start a Compost” brochure
  • Holding demonstrations on:
    • How to Start Compost
    • What to Compost?
    • What is a bio-digester and how does it work?
  • Create a Public Service Announcement
  • Lobbing for legislative changes
  • Starting community compost bins
  • Scouting locations in the town of Greenburgh where bio-digesters could be placed
