“These time-intensive handling techniques on Earth are less necessary in the energy-rich environment in orbit. Since 2009 astronauts on the International Space Station have been drinking their own recycled urine, which they sometimes refer to as “yesterday’s coffee.” Their process uses intensive heating and treating and also spins the water in a high speed centrifuge to pull contaminants downward and outward, replicating the spin of the Stanford Torus in miniature. On Earth the Farallones Institute suggests collecting urine in watering cans and tea kettles, carefully diluting it at a five-to-one ratio with water, distributing it evenly and regularly in the garden, and making sure that it is sourced from “family members, and only when those contributing are in good health. In both Faralllones book and in the Summer Study report, the arrays of network diagrams include food webs [77].
Figure 96: How to Dispose of Cooking Oil? [230]
Cooking oils can be filtered and reused into items such as bio-fuel, beauty care products, and stock feed. In case of not conceivable to reuse cooking oil, arranging it accurately is crucial. Disposing cooked oil into drains and sinks can cause plumbing and environmental problems. Household cooking oil should be stored in a sealable jar or wiped up with absorbent paper then it can be placed in the waste bin [231]. Step 1: Cool oil and grease Step 2: Cleaning oil and grease from contaminated equipment: For disposing small amounts of oil and grease, paper tissues and paper-like materials can be used as a wiper then It can be placed in the compost. For disposing large amounts of oil, using a container with a closed lid to inserting oil in it is a suitable solution to placing near the recycling container. Large amounts of grease can be scraped into a container, covered with a lid, and placed in the garbage [232]
