Our role in protecting the environment doesn't end with water recycling. We aim to beneficially re-use as many of the by-products of wastewater treatment as possible. In some cases, we can turn waste into valuable products like biosolids and renewable energy.

We produce organic solids (sludge) during wastewater treatment.
\r\nThis sludge is collected and processed to convert it into a safe, stable, nutrient rich fertiliser product called biosolids.
\r\nNSW Health and NSW Environmental Protection Authority (EPA) have confirmed biosolids are safe if they are made and used following the EPA’s biosolids guidelines.
\r\n
\r\nThe National Association of Testing Authorities accredit the laboratories that test all our biosolids for contaminant levels and stability. This determines the grade of product and how the biosolids should be used.

收集并处理该污泥，以将其转换为一种称为生物固醇的安全，稳定，富含营养的肥料产品。
新南威尔士州健康和新南威尔士州环境保护局（EPA）已经确认生物固醇是安全的，如果它们被制成并使用后使用EPA的生物固体指南。
这全国测试当局协会认可测试我们所有生物固体的实验室，以确保污染物水平和稳定性。这决定了产品等级以及如何使用生物固体。

A circular economy is a set of principles that values all things as resources rather than products and waste. It aims to eliminate waste, circulate products and materials so they're used more than once and regenerate nature.
\r\nWe used to think of the solids left over from wastewater treatment as waste products to be disposed of. But, when we look closer we find that they're full of useful resources – things like organic matter, nutrients and healthy bacteria. Valuing and re-using resources found in wastewater, like biosolids, is part of circular economy thinking.
\r\nCan you think of other connections between water, materials and energy? It's something we're working on.
\r\nWe can draw inspiration from the Earth's natural cycles including the natural water cycle, nutrient cycles (like the nitrogen cycle in wastewater treatment) and energy cycles.

我们曾经将废水处理中留下的固体视为要处理的废物。但是，当我们仔细观察时，我们发现它们充满了有用的资源 - 诸如有机物质，营养和健康细菌之类的东西。像生物固体一样，在废水中发现并重复使用资源是循环经济思维的一部分。

We use some biosolids directly without further processing. Some biosolids go on to be processed further for indirect uses.
\r\nAround 73% of the biosolids produced from our treatment plants are directly applied to agricultural soils.
\r\nOver 40 farms across the central west and south west of NSW use our biosolids to help improve soil, mainly in broad-acre farms.
\r\nThese large farms grow canola, wheat, oats, barley and pastures.
\r\nThe biosolids are spread and mixed into the soil before sowing the crops. The harvested parts of these crops don’t come into direct contact with the soil/biosolids mixture.
\r\nSome animals, such as sheep and cattle, may graze on crops and pastures grown in biosolids. There are withholding periods for farm animals fed on biosolids-treated pastures.

We send the remaining 25% of our biosolids for further processing. Biosolids can be mixed with other materials such as green waste and further composted. These products are tested to ensure they're safe for use in the same way as any other composted product.
\r\nThese composted biosolids are used in agriculture, horticulture, mine rehabilitation and gardens and parklands within Sydney.

Cogeneration is the production of electricity and heat at the same time.
\r\nWe can use the electricity and heat to reduce the overall energy demand of a wastewater treatment plant.
\r\nIn a wastewater system, the anaerobic digestion of organic waste can be used to produce methane gas.
\r\nThis gas can be used to power a combustion engine that drives an electricity generator.
\r\nThe heat generated from the combustion engine can then be used to warm the digester and improve its efficiency.
\r\nWe already use cogeneration at a number of plants. We're looking to increase our cogeneration capacity at Bondi, Malabar and North Head.

Co-digestion takes liquid organic waste from restaurants and other sources and combines it with solids from the wastewater system. This mix is then digested to produce methane gas and biosolids.
\r\nIn late 2011, we began exploring the possibilities of co-digestion and the benefits of treating organic waste as a resource at Cronulla Wastewater Treatment Plant.
\r\nThis work is still in the early stages, but it's producing some impressive results with a lot of promise for the future.
