About Zero Waste Classes

I tailor my class for the organization and my audience.  This is a sample of my typical class topic;

Class: Your Zero Waste Home; Save Money While Living a Sustainable Life

With an emphasis on financial and resource effectiveness, this class will adds value to your daily routine regardless of your budget, lifestyle, or how much you want to hug a tree. Topics will include food and personal care product waste, shopping tips and tricks, housekeeping and zero waste skills, our actions and how they shape the world’s behaviors, and resource mindfulness. Attendees will leave this class better prepared to deal with the onslaught of waste associated with the activities of daily living.

Classes can be from 1-2 hours in length.

I can speak to 10 or 1000 people.

All classes have an environmental education component to them but are presented as accessible and helpful.



Horse Chestnut laundry detergent (Don’t Eat these chestnuts!)

I was literally driving down the road and saw Horse Chestnuts on the side of the busy rural highway, hung a u- turn and decided to fill a cloth bag (of course it was cloth) with the nuts littering the shoulder. I had seen a few posting on Instagram about making laundry detergent from Horse Chestnuts and right then and there decided to give it a try.

After some internet research and a lot of nonspecific recipes, I came up with a recipe that I think works pretty well:

To make the dry stage of the process you start with:

  • Pounds and pound of fresh Horse chestnuts without the hull (green spiky flesh that surrounds the nut). I read that you need 10-20 pounds of raw shelled nuts to get you through one year. I am collecting around 20- 30 pounds this year (yes, I do lots of laundry).
  • Process the hulled nuts with either a grater, hammer, or food processor with a grating wheel/blade. I used my mothers food processor’s grating wheel.IMG_20171001_151255_308
  • Then put them in a blender, in batches, to make a pulp. Repeat.
  • Place a layer of the pulp on a cookie sheet and dry in your oven for 1-1.5 hours on 200 degrees Fahrenheit or until nice and dry.  You will need to do this stage in batches. Cool and then place in a jar to store your “detergent”.  Repeat. This dry stage will keep for 18-24 months in an air tight container.

To make the liquid washing solution: makes 2-4 loads (depending on load size and machine requirements). Don’t make a large batch of solution, it goes bad in about 7 days in the fridge.

  • Place about 1/2 cup dried nuts in a jar and cover with 1 cup boiling water, let steep for 15-30 minutes, strain through a fine sieve.the liquid will be a milky yellow/white solution (where will be some fine bits of chestnut in the bottom of your jar, that’s okay. I carefully pour my solution when I use it and always leave a little solution at the bottom of my jar with the bits, when it is empty.
  • One load uses 1/4 cup -1/2 cup solution (depending on load size and machine requirements)
  • I added 5-8 drops of Lavender or peppermint essential oil to the solution to make my laundry smell fancy.
  • If you make a bunch of solution a head of time, store it in the fridge. I should last about 7 days.

Have fun with this recipe. I sure am excited about this rediscovered zero waste recipe.

I might just try to wash my hair with a chamomile/horse chestnut shampoo. Keep you posted on that one.IMG_20171002_122345_359

10 things to do; Half way there

Day 5: 3.5 billion tooth brushes are sold world wide every year and lets say each toothbrush represents 2 plastic box of dental floss. 7 billion plastic dental floss boxes go along with those 3.5 billion toothbrushes. That is a whole lot of plastic trash that isn’t recyclable, burnable or compostable. These things sometimes end up in the water ways and oceans adding to the giant plastic geyers  in the Pacific Ocean.

Solution: Change to a compostable bamboo toothbrush and dental floss that comes in paper or glass. When the toothbrush is worn out you pull out the bristles (those go in the trash) and the handle goes into the compost. That dental floss box into the recycle. Done!

This is a really easy replacement, we all use a toothbrush and floss.

10 Things To Do; a day at a time Zero Waster

Over the last 6 plus years my family has reduced our garbage by 85%. I really enjoy spreading the Zero Waste lifestyle in a way that is easy and accessible to everyone. By listing some typical and non-typical 10 Things To Do, you can start the process of becoming a Zero Waster. I will be listing daily bits of information about waste, consumerism and environment with a Zero Waste option. So, here we go!

Day 1: According to Pristineplanet.com 50 million plastic water bottles are thrown away each day and thebetacup.com says, 58 billion paper coffee cups are thrown away each year. 10 billion trees are used each year to feed our disposable coffee cup addiction word wide. And that is just the vessels not even the lids. That is a ridiculous amount of preventable waste.

Solution: Keep a refillable metal or glass water bottle with you (learn to love tap water) and get yourself a reusable insulated coffee cup. These are solutions we hear of everyday but how many of us actually implement these simple things? Not as many people as one would hope.  This an affordable change you can make especially if you buy second hand. For just a few dollars you can stop these two prolific pollutants.

The Purchase Process of a new pen

I know it doesn’t seem very exciting but, I got a new pen to try out before I buy them for the whole family. Plastic single use pens are a struggle to replace. I can’t write checks with a pencil,  nor can I fill out forms that aren’t online and are necessary. So, what to do? I started my Purchase Process to get a ink drawing refillable fountain pen.  Like many of the things I choose to purchase at our house, I have to look much further into the lifecycle of that product, I call it our Purchase Process. This is an example of my Purchase Process of my new pen; Do I need this? Yes, I have no more disposable pens. Can I buy it used? Tried, but often they don’t work right. Can I buy it local? Nope. How and what is this made with? Made with Bamboo a renewable and sustainable grass. How do I dispose of the majority or all of the product when it comes to the end of its lifecycle? I can compost the bamboo shell of the pen, recycle the metal fittings and bits of the plastic mechanism, part of it will need to go into the garbage.  Do I like the pens style (just a bit vain but, for me important)? Yes,  it is cool looking. Sometimes I add in the mix, where is it made? Unfortunately, in China. Can’t always score 100%.  This is an example of how my Purchase Process goes. How does your Purchase Process go? Think about it if you haven’t.
