About 400 pounds of food is wasted per day from 5 pm to 8 pm in Douglass Dining Hall. "We scrape（刮掉） the food from the conveyor belt into the buckets by hand.Working for Dining Team Green，I don't expect to basically become a garbage girl，" Roll said. "We do the work because we care much about it.We all have a responsibility to take care of the environment. "
   To have more approachable composting（把……制成堆肥） machines on campus，Roll now has a new sustainable project investing in Lomi，an automated compost machine. "I learned about Lomi through an ad，" Roll said. "Funny enough，I just saw it and thought it perfect.It really interested me how the mechanism worked. "
   Lomi is a new technology that can break down food waste into natural compost.According to Roll，it breaks down waste in the way：grinding（碾碎） the food into plant fertilizer.Unlike most composting machines，Omi can compost animal products，such as small bones.Another huge benefit is that it doesn't have smell and can convert waste to compost in a shorter time.
   Roll plans on using the compost in the Gilbert community garden so that Dining Team Green can give back to the community. "It's very exciting to see our food waste that would otherwise have gone in the trash and pollute the environment go to our community，" she said.
   Roll is excited to introduce a new form of composting to the residents.She hopes that this machine will inspire other composting machines in all residential buildings. "I want Lomi not only to be a way to reduce food waste on the floor，but an educational tool to make people compost in a real way and not just talk about it in a theoretical sense，" Roll said.
