Incinerating toilet

Incinerating toilet is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Incinerating toilet rather than just read about it. In short: An incinerating toilet is a type of dry toilet that burns human feces instead of flushing them away with water, as does a flush toilet. The thermal energy used to incinerate the waste can be derived from electricity, fuel, oil, or liquified petroleum gas.

Key takeaways

Incinerating toilet belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Incinerating toilet to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Incinerating toilet from memory before moving on to harder problems.

Reference excerpt

An incinerating toilet is a type of dry toilet that burns human feces instead of flushing them away with water, as does a flush toilet. The thermal energy used to incinerate the waste can be derived from electricity, fuel, oil, or liquified petroleum gas. They are relatively energy inefficient because of the fuel used.

History

The first commercially successful incinerating toilet was the Destroilet, patented in 1946. Destroilets were used on ships in the 1960s when laws were passed to prevent the dumping of raw sewage into American waterways. In 2011, the Bill & Melinda Gates Foundation launched the "Reinvent the Toilet Challenge" to promote safer, more effective ways to treat human excreta. Several research teams have received funding to work on developing toilets based on solid waste combustion. For example, a toilet under development by RTI International is based on electrochemical disinfection and solid waste combustion. This technology converts feces into burnable pieces and then uses thermoelectric devices to convert the thermal energy into electrical energy.

Design Incinerating toilets may be powered by electricity, gas, dried feces or other energy sources. Incinerating toilets gather excrement in an integral ashpan and then incinerate it, reducing it to pathogen-free ash. Some will also incinerate "grey water" created from showers and sinks.

Applications Incinerating toilets are used only for niche applications, which include:

Apartments with limited or difficult access to waste plumbing. Houses without access to drains, and where building a septic tank would be difficult or uneconomic. On yachts and canal barges, as an alternative to a blackwater holding tank, which needs to be pumped out occasionally. On mobile homes, recreational vehicles and caravans/(trailers).

Worked examples

Example 1 — a first encounter with Incinerating toilet

Start with the simplest possible case. Write down what Incinerating toilet claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Incinerating toilet before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Incinerating toilet ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Incinerating toilet

In research: Incinerating toilet appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Incinerating toilet in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Incinerating toilet is common in secondary-school and first-year university syllabi. It links to neighbouring topics Incineration, Toilets, so understanding it makes those chapters shorter.
In everyday life: Look for Incinerating toilet outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
