Webinar Resources: Using Bokashi in Community Composting — What, Why, How, Who

Date: 30 Apr 2018 | posted in: Composting | 0 Facebooktwitterredditmail

On Wednesday, April 18th, the Institute for Local Self-Reliance hosted a webinar on, “Using Bokashi in Community Composting: What, Why, How, Who.” This was one in a series of webinars oriented toward community composters, and offered on behalf of the community composter network. View the recording here.

Bokashi is a Japanese term meaning “fermented organic matter.” Bokashi fermentation utilizes a variety of by-products – such as leaves, sawdust, husks, bran, other grains – inoculated with beneficial microbes to ferment kitchen waste. It is an anaerobic (without oxygen) process, akin to pickling. Often mistakenly considered a form of composting, it results in a very different product. However, as a pre-processing step to composting, it has several benefits including ability to handle meat and dairy, repelling rats, speeding up the composting process, and cutting frequency of food scrap collection. The webinar covered what bokashi is, how it’s made, benefits of bokashi to micro food scrap haulers and composters, and lessons from three micro composters.

New York City
Facebook: Vokashi Kitchen Waste Solution

Founder and President of Vokashi, Vandra Thorburn is a huge advocate of bokashi and EM-1, the original microbial inoculant. While researching ways to implement a compost collection service, Vandra learned about the many applications of bokashi and visited EMRO (Effective Microorganisms Research Organization) in Okinawa, Japan. For the past 8 years, Vokashi has demonstrated that food scraps can be saved for long periods of time in an airtight container using EM-1 inoculated bran. Vandra will share the value of pit and trench composting, using these fermented food scraps, and how her bokashi bran and collection bucket takes the yuck out of recycling food waste.
