Some factories in Taiwan are dedicated to extract high-water-content food waste, resulting 2 different forms of waste; solid and liquid using high temperature and high pressure.
The liquid extract is estimated to still have the nutrients or organic matters that can be used in agriculture or aquaculture as feed of beneficial microorganisms such as probiotic bacteria or zooplankton without decreasing the water quality.
What do you think of this?
I think there is inspiration to be found in an old cultural system: https://en.wikipedia.org/wiki/Rice-fish_system
This innovation is novel and it will reduce the cost of production in the short to long term.
I welcome this idea and see myself learning on how it works
there are many potential benefits to the use of food waste for aquaculture feed, its success will rely on its nutrient profile and bio availability. Re-utilizing food waste is complicated because of the highly variable composition, making it almost impossible to obtain consistent batches.
Feed prepared from food waste will suit omnivorous fish species of low commercial importance. The nutrition profile of this feed will have more carbohydrate than protein content. Species selection is very important for this new feed preparation approach and this idea is not suitable for marine fin and shellfish culture.
It is possible to use food waste as feed for aquaculture, depending on the specific types of food waste and the species of aquaculture being raised. However, there are several factors to consider when using food waste as feed, including the nutritional value of the waste, the potential for contamination with toxins or pathogens, and the environmental impacts of food waste disposal.
Food waste can be a valuable source of nutrients for some species of aquaculture, such as tilapia, catfish, and carp. These species are omnivorous and can utilize a wide variety of feedstuffs, including plant-based materials and food waste. However, it is important to consider the nutritional value of the food waste and to supplement the diet with additional nutrients as needed to ensure that the aquaculture species are receiving a balanced diet.
There is also a potential risk of contamination with toxins or pathogens when using food waste as feed, as some types of food waste may contain chemicals or bacteria that can be harmful to the aquaculture species or to human consumers. It is important to carefully assess the safety and quality of the food waste before using it as feed, and to follow proper handling and storage guidelines to minimize the risk of contamination.
There are also environmental considerations to take into account when using food waste as feed for aquaculture. Food waste disposal can contribute to greenhouse gas emissions and other environmental impacts, and using food waste as feed can help to reduce these impacts. However, it is important to carefully consider the potential environmental impacts of using food waste as feed, and to take steps to minimize any negative impacts.
In summary, it is possible to use food waste as feed for some species of aquaculture, but it is important to carefully consider the nutritional value, safety, and environmental impacts of food waste before using it as feed.

The idea of using food waste as a source of nutrients for aquaculture or agriculture is an interesting concept that has been gaining attention in recent years. The extraction of liquid from high-water-content food waste using high temperature and high pressure can potentially provide a nutrient-rich solution that can be used as a feed source for beneficial microorganisms in aquaculture or agriculture.
However, it is important to ensure that the liquid extract is properly treated and processed to ensure that it is free from harmful contaminants and pathogens. Additionally, the use of liquid extract as a feed source should be carefully evaluated to ensure that it does not negatively impact the health and growth of the target organisms, and that it does not adversely affect water quality.
Overall, the use of food waste as a source of nutrients for aquaculture or agriculture can be a sustainable and cost-effective approach, but it is important to carefully evaluate the potential risks and benefits before implementing such practices on a larger scale.
