Dr. Elliot Swartz: The environmental impacts of cultivated meat production
1. Cultivated Meat uses up to 78% less water than conventional meat
Studies reveal that producing Cultivated Meat requires approximately 3,100 litres of water per kilogram of protein - a figure that’s up to 78% lower than the water needed for conventional beef production [2]. To put this into perspective, traditional beef production typically consumes between 14,000 and 15,000 litres of water per kilogram of protein, making Cultivated Meat one of the most water-efficient protein options available.
The bulk of water used in conventional beef production goes towards irrigating feed crops, which contributes significantly to its overall water footprint. Even pork and poultry, which demand less water than beef, still use considerably more water than Cultivated Meat. By eliminating the need for water-intensive feed crops, Cultivated Meat not only cuts water usage dramatically compared to beef but also brings additional benefits for water conservation.
Pilot projects and academic research back up these savings, suggesting that further advancements in techniques like media recycling and process optimisation could enhance efficiency as production scales [2].
For the UK, these reductions in water use could play a key role in meeting sustainability targets while safeguarding essential water resources.
| Protein Source | Water Use (litres per kg of protein) | Estimated Extra Water Use vs. Cultivated Meat |
|---|---|---|
| Conventional Beef | 14,000–15,000 | Up to 78% more water used |
| Conventional Pork | ~6,000 | Around 50% more water used |
| Conventional Poultry | ~4,300 | Around 30% more water used |
| Cultivated Meat | 3,100 | Baseline (most efficient) |
2. No manure or fertiliser runoff means cleaner water systems
Traditional meat farming in the UK has a significant impact on water quality. Manure and fertiliser runoff from farms often ends up in rivers and lakes, degrading water systems and harming aquatic ecosystems. According to the Environment Agency, agriculture accounts for around 40% of water bodies failing to achieve good ecological status. Heavy rainfall exacerbates the problem, washing manure and fertiliser into waterways, leading to issues like fish deaths and algal blooms - problems frequently observed in rivers such as the Wye [1]. This runoff fuels eutrophication, where excessive algae growth depletes oxygen levels, creating lifeless "dead zones" in the water.
Cultivated Meat offers a cleaner alternative. Unlike conventional farming, its production occurs in a controlled setting that eliminates manure and fertiliser use entirely [2]. Every input and output is meticulously managed, and wastewater is treated on-site, removing the risk of pollution reaching nearby rivers or lakes. To put this into perspective, producing conventional pork or poultry requires hundreds of grams of fertiliser and over 10 cubic metres of water per kilogram - resources that Cultivated Meat production avoids altogether. Studies even suggest that replacing just 10% of traditional meat with alternatives like Cultivated Meat could lower nitrate levels in groundwater by up to 20% and reduce manure production by 10.7% [2]. This approach not only drastically reduces resource use but also helps protect the UK's freshwater systems, ensuring cleaner and safer drinking water for everyone.
3. Eliminates water-intensive feed crops in the supply chain
Cultivated Meat dramatically reduces the need for water-intensive feed crops, a cornerstone of traditional meat production. Conventional farming relies heavily on crops like maize, soy, and alfalfa to feed livestock. To put it into perspective, producing just one kilogram of beef requires around 15,400 litres of water - an astonishing 98% of that is used to grow feed crops [1]. This heavy dependence on water-hungry crops highlights the efficiency of Cultivated Meat's production process.
Instead of raising animals, Cultivated Meat grows cells in controlled environments, using a specially designed growth medium. This method sidesteps the massive water losses associated with crop irrigation [2]. For instance, producing one kilogram of Cultivated Meat requires just 3.1 cubic metres of water, a fraction of the 17.2 cubic metres needed for conventional pork [2]. On a global scale, livestock feed production consumes about 4,387 cubic kilometres of water annually - accounting for 41% of all agricultural water use [3].
In some cases, farms even import feed crops from regions already struggling with water shortages, particularly in intensive farming systems. By eliminating the need for these feed crops, Cultivated Meat provides a far more water-efficient alternative. It ensures we can meet protein demands without placing additional strain on the world’s limited freshwater resources.

4. Production facilities use less water than farms
Cultivated Meat production facilities are built with water-saving measures at their core, using far less water than traditional livestock farms. To put this into perspective, UK beef farms consume over 15 million litres of water per tonne of meat produced, while a Cultivated Meat facility requires less than 3,100 litres for the same output [2][4]. This drastic reduction is made possible by advancements in production design.
Traditional farming methods demand huge amounts of water for tasks like irrigating feed crops, hydrating animals, and cleaning livestock housing and abattoirs. In contrast, Cultivated Meat facilities utilise closed-loop systems that capture, filter, and recycle water, significantly cutting down on water consumption compared to traditional practices [2][5]. For example, while conventional abattoirs use between 700 and 1,000 litres of water per animal for cleaning, Cultivated Meat systems employ automated cleaning processes that recycle water efficiently [5].
Another key factor in reducing water use is the precision of Cultivated Meat production. Nutrients are delivered directly to cells in controlled bioreactors, avoiding the substantial water losses associated with outdoor farming. This process also allows for real-time monitoring and fine-tuning of water usage, ensuring efficiency at every step [2].
For those in the UK curious about these water-saving technologies, more information is available through Cultivated Meat Shop [2][4].
5. Renewable energy could cut water use even more
Renewable energy sources like wind and solar are game-changers when it comes to water conservation. Unlike fossil fuel plants, which can consume thousands of litres of water per megawatt-hour for cooling and steam generation, wind and solar energy require very little water. This creates a solid foundation for efficiency. However, a chunk of the water footprint in Cultivated Meat production still comes from the energy used to power production facilities - especially when that energy is sourced from fossil fuels. Studies show that using 100% renewable energy can slash both water use and greenhouse gas emissions by more than 50%, largely by eliminating water-heavy cooling processes. This underscores how switching to renewables can make Cultivated Meat production even more water-efficient.
The focus on saving water doesn’t stop there. Transitioning to renewable energy is a natural next step in creating smarter, more efficient production methods. Across the UK food industry, the move to clean energy is already gaining momentum. Future Cultivated Meat facilities are being designed with sustainability in mind, featuring on-site solar panels, wind turbines, and connections to renewable energy grids. By powering facilities with renewable electricity and optimising designs to reduce energy and water usage, producers can take efficiency even further. For a deeper look at these advancements, Cultivated Meat Shop offers valuable insights into this forward-thinking approach. Since the carbon footprint of Cultivated Meat heavily depends on the energy mix used, adopting renewables is key to achieving both water conservation and climate goals.
