FAQs: What’s Allowed in Green Bins Growing?

Wondering if Green Bins Growing office food waste recycling service accepts items like meat/diary/citrus, coffee cups or bio-plastics? Our collection bins come with signage detailing what is and isn’t accepted but certain questions come up time and again… Here are answers to our most frequently asked questions:


Orange peel
Orange peels are accepted!

Q. “I’ve heard you can’t feed citrus / meat / diary to worms…does Green Bins Growing accept these materials?”Jen at Bullfrog Power

A. Yes, Green Bins Growing accepts ALL organic material in our bins, including citrus, meat and diary.

While at-home worm bins have trouble with these materials because they can overwhelm a small worm eco-system (citrus, for example, has anti-microbial properties that harm the hard-working beneficial bacteria required) because we grow our worms on an industrial scale and pre-treat our food waste, we don’t have to worry about this; we’re happy to accept meat, citrus and diary in our bins!


starbucks coffee cup
Coffee cups welcome!


Q. “Paper coffee cups aren’t accepted in our blue bin, can we throw them into the Green Bins Growing bin instead?”Amy at David Suzuki Foundation

A. Yes, we do accept paper-based coffee cups and takeout containers in our bins, even those with small amounts of plastic or wax coating.

            The worms will eat the paper clean off the plastic coating, which we then retrieve from the worm bin and place in the recycling.  But please, no plastic lids or Styrofoam cups in our bins!

Coke's plant bottle is made to be recycled with other plastics
Many bio-plastics are made to be recycled with traditional plastics




Q. “Will the worms eat bio-plastic?”Patrick at Velcro Canada

A. Tricky question… it depends on the TYPE of bio-plastic.

Many bio-plastics are actually made to be recycled with traditional plastic, such as Coke’s PET “plant” bottle.  Some bio-plastics such as PLA (poly-lactic-acid) are perfect for worm composting and easily break down in the worm eco-system.  Other types of bio-plastic require the high-heat of traditional composting processes to trigger material degradation, so these types are not suitable for the worms as processing temperatures doesn’t get warm enough.  Bio-plastics made from corn or soy are also not a good fit for the worms because these materials are made from seeds and worms know not to eat seeds!! (Nothing would ever get a chance to grow if they did!)  The best bet when looking for disposable crockery to use with Green Bins Growing office food waste recycling is to use paper or hemp based materials.
