WAYS TO PREVENT WASTAGE

  1. Use a reusable bottle/cup for beverages on-the-go

You might already have a reusable water bottle, but do you use it all the time? You can put that reusable bottle to use, save money and reduce waste. By taking your own water with you, you’ll also reduce your chances of purchasing more expensive beverages on-the-go. This will eliminate the one-time use containers they come in.

  1. Use reusable grocery bags, and not just for groceries

Just like a reusable water bottle, you may already have a reusable grocery bag, though it’s often forgotten at home. Try writing BAGS on the top of your grocery list to help you remember, or keep them in the back seat where they aren’t as easy to forget.

  1. Purchase wisely and recycle

You can reduce the amount of waste you produce by purchasing products that come with less packaging and/or come in packaging that can be recycled.

  1. Compost it!

Did you know as much as 25% of the items in your trash could potentially be removed from the waste stream and composted in your back yard?

Your fruit and vegetable scraps, egg shells, coffee grounds, grass clippings and leaves can all be composted. While composting requires more effort than the previously mentioned lifestyle changes, it will provide you with a beneficial return on your investment of time and effort. Depending on the conditions, you may have compost in 3 to 12 months to use in your garden. You’ll save on fertilizers and if you grow your own vegetables, you’ll likely see improved yields

  1. Avoid single-use food and drink containers and utensils

Whenever possible, try to avoid single-use coffee cups, disposable utensils, straws and napkins.. Keep a set of silverware at work along with a plate, bowl and cup that you can wash and reuse. Skip the plastic straw altogether or buy reusable metal ones instead. 

  1. Buy secondhand items and donate used goods

Before you go buy something new, consider buying it used which can also save you lots of money. By purchasing secondhand items you’ll be supporting local charities in addition to saving items from ending up in the dump.

  1. Shop local farmers markets and buy in bulk to reduce packaging
  2. Curb your use of paper: mail, receipts, magazines
