What can and what can’t!

What can be composted and what cannot be composted:

  • All your vegetable and fruit wastes, (including rinds and cores) even if they are mouldy and ugly
  • Old bread, donuts, cookies, crackers, pizza crust, and noodles: anything made out of flour!
  • Grains (cooked or uncooked): rice, barley, you name it
  • Coffee grounds, tea bags, filters
  • Fruit or vegetable pulp from juicing
  • Old spices
  • Outdated boxed foods from the pantry
  • Egg shells (crush well)
  • Corn cobs and husks (cobs breakdown very slowly)
  • Meat or meat waste, such as bones, fat, gristle, skin, etc.
  • Most Cooked food
  • Fish or fish waste
  • Dairy products, such as cheese, butter, cottage cheese, yogurt, cream cheese, sour cream, etc.
  • Grease and oils of any kind

Why can’t you compost
these food wastes?

  • They imbalance the otherwise nutrient-rich structure of other food and vegetation waste and breakdown slowly
  • They attract pests
  • Meat attracts maggots
  • Your compost bin will have an odour.

This table is adapted from “Home composting made easy”, U.S. America <http://www.homecompostingmadeeasy.com/index.html >, written by avid gardeners Dr. C. Forrest McDowell and Tricia Clarke-McDowell. The above table has also been edited with cross referencing from “Start Composting at Home” Singapore, Written by Eugene, <http://www.zerowastesg.com/2009/02/04/start-composting-at-home/ >. 

So let’s see, the following are pictures and whether or not they can be composted alright?

Can Compost!

Yes! Can Compost!

NOOO! Cannot Compost!

Yes Can Compost!

NOOO! Cannot Compost this!

Hope you guessed them all right! (:

Will have more quizzes in future! But sorry, there aren’t any prizes! The only prize is the satisfaction gathered from your intellectual performance!

    Thank you for those helpful and interesting pictures, I think it would really help to promote composting to the illiterate and the apathetic. In addition to luncheon meat, I’m sure unprocessed meats are also bad for composting. In my previous composting (mis)adventures, I’ve tried putting the Japanese curry into the bin to promote microbial cultures (I’ve heard that the nutritious gravy is good culture for actinomycetes), however, a few days later, I spotted maggots on the surface of the chicken chunks. Luckily I spotted those early and squashed them to bits, or I would have had a pest epidemic! (by the way, dead maggots can be composted too!)
