New Skills in 2014: Build a Compost Toilet

We have a host of exciting short courses taking place at CAT in 2014, and up until the end of January there’s 10% off!  From the 4th to the 6th of July discover the power of poo during our ‘Build a Compost Toilet’ short course.

Although the vast majority of the UK’s houses are connected to the mains, there are some that must find alternatives to local sewage treatment works. Compost toilets can be efficient and practical, resulting in nutrient-rich soil to be used in the garden. They don’t use any water, although most types of toilet need a fair bit of room to allow composting to occur at a steady pace.

During this three day course the essentials for building your own compost toilet will be covered. With Grace Grabb, CAT’s water and natural resources specialist, course participants will learn about the changes human waste undergoes during the composting process. CAT’s resident carpenter Carwyn Jones will then demonstrate some of the techniques needed to build your own compost toilet.

Composting your waste is a relatively easy and cheap way to reduce your waste and constructing your own toilet can be great fun. The soil produced after a year or two is pleasant to remove, and can be put straight on the garden (although preferably on non-food plants). Compost toilets are increasingly being built in allotments, back gardens and even indoors. Addition of the right amount of ‘soak’ gives good decomposition. A ‘soak’ is a source of carbon – typical materials include sawdust, straw and earth. The four main components to make your compost a nutrient-rich success are: heat, moisture, oxygen and a little dedication!

From DIY to ‘off the shelf’ designs, this course can help you decide whether or not a composting toilet is right for you. The course invites anyone and everyone to join in, from urban gardeners to off-grid enthusiasts. Pupils will learn more about construction and cladding methods, as well as the biological processes that happen deep within the soil on a molecular level.

To discover a more holistic approach to waste management, sign up for the course now.

For those more interested in the theory behind compost toilets, rather than the construction methods, we offer a one day course: Introduction to Compost Toilets. This forms the first day of the Build a Compost Toilet course, and can be taken independently.

Remember, we are offering a 10% on courses booked before the end of January. For terms and conditions please visit our website.

    A composting toilet workshop? That’s awesome. I am not aware of any in Australia but that sounds like a really good idea.

    We’re really pro-composting toilet and hope they’re embraced more in urban areas, as the myths get blown out the proverbial. In fact, we bust some of those myths here:
