Event Description

Please join us for a worm composter workshop where you will learn and build your own worm composter that you can take home at the end of the course.

Beyond buying local food, part of food security and sustainability is to acquire all the required growing materials, including fertilizer, soil and seed, locally. According to, as much as forty percent of energy used in the food system goes towards the production of artificial fertilizers and pesticides. And according to the Soil Conservation of Canada on a fact sheet on "Global Warming and Argriculture: Fossil Fuel", nitrogen-based fertilizers contribute directly to global warming.  Making and transporting one kilogram of nitrogen in a fertilizer releases 3.7 kg of carbon dioxide into the atmosphere.

The cost of the course is $28 dollars and $18 if you bring your own tote bins.  Be SURE to RSVP and indicate whether you will bring a bin or not so that we know how many bins we need to supply.  

Also, please bring some work gloves if you don't want to directly handle coffee grinds and worms.

Requirements for the bins:  large roughneck bin with a fitted rubber lid made out of durable rubber, and either a lid or a smaller bin that the large bin can sit inside for drainage.

If we could make fertilizer out of food and yard waste with composting worms such as red wigglers and perhaps take our sewage waste and convert it to commercial fertilizer, we can significantly reduce our carbon emissions. Making artificial fertilizers out of petroleum products shipped from half way around the world, just doesn't make a lot of sense.

Hey YP, Dash and Andrew,

Thanks for hosting this fun and educational workshop! It's so great to finally have worms (never thought I'd say that). Hope to see everyone around the movement.

Thanks everyone for attending the workshop. I had lots of fun and learned alot from everyone there. Hope to see you all at the "Energy Descent Action Theatre". I will follow-up with an email tomorrow with my contact info. Please email me if you have any trouble with your composter and if your worms don't make it. I can supply you with another pound or two in the spring!

Happy composting!

Is it too late to RSVP? I don't have my own bin.

Hi Kate,

Thanks for RSVP'ing and bringing your positive energy. I love worms and composting. For me it is a poetic cycle of looking at our waste and sustainably cycling it back into our food system.

I am excited about the workshop too and am looking forward to meeting like-minded individuals!

Hi YP- 

I'm super excited about your composting event- 

I have just RSVP'd and would like to build a container (E.g. the $28 option). 

Thanks so much, and see you tomorrow.

Hi Michael,

That is not a problem.  You may have to split/sell/give your worms away once or twice a year to make room for compost.

You need a lid to cover it and a lid or a tote for it to rest in so that compost liquids can drain out.

Hi YP,

I have a tote that is 14 x 10 x 7 (what I would consider small) and I have the perfect place for it in my apartment. Is it ok if I make my bin this size?

Thanks and please let me know
