Food Waste

Just a few generations ago, meat was a luxury and it would have been considered unethical to waste any part of an animal. Thankfully, the recent vogue for nose-to-tail eating is leading the way in a revival of forgotten cuts and more adventurous traditional dishes. Tongue, cheek, liver and kidney are all highly nutritious as well as cheaper than the prime cuts, and we hope you’ll be inspired to try some of our delicious recipe suggestions. We are now using a very clever composting machine to breakdown the majority of our meat waste and any other biodegradable products we use.

Pasture-fed, organic, free-roaming

Because we use no inputs – no fertilisers or other chemicals, no high-energy feeding systems, buildings or farm machinery – the method of meat production at Knepp is entirely sustainable. Permanent pasture is one of the most effective systems of carbon sequestration we have on the planet. The grazing and browsing of animals stimulates the growth of roots and mycorrhizal fungi underground and new shoots and foliage above ground, in a continuous recycling of carbon. 

The animals’ organic dung and urine returns nutrients to the soil, stimulating the actions of dung beetles and other invertebrates that pull the dung underground, restoring soil structure and fertility. We’ve found as many as twenty-three different species of dung beetle in a single cow pat; and one large dung beetle, the violet dor, which hasn’t been seen in Sussex for fifty years, is now plentiful at Knepp. Since 2000 when we gave up conventional farming and embarked on rewilding, we have more than doubled our total soil carbon, soil organic matter and microbial biomass, and more than tripled our soil mycorrhizae.


We’re always aiming to be ahead of the game in reducing packaging and sourcing recycled and recyclable materials. The majority of our vacuum packaging is made from recyclable plastic, however the supplies of these are very erratic at present and we are unable to guarantee all our vacuum bags are recyclable – but we will ensure our customers are aware as we change completely to biodegradable and recyclable products. Our delivery boxes are insulated using sheep’s wool from Woolcool and cooled by Hydropac’s food-grade water ice-packs which are completely recyclable or reusable.

Copper bullets

Every year our deer populations are culled. With no natural predator, it is essential to limit the stocking density to ensure all our animals are able to thrive outside all year round. Lead has been traditionally used in ammunition for centuries. However, new evidence suggests that contamination of the animal and the surrounding environment is potentially dangerous. The UK Food Standards Agency states: “There is no agreed safe level of lead intake” and that exposure to lead “should be reduced as far as possible”. The switch to non toxic bullets limits the damage to the environment and offers a safe, non-toxic alternative to traditional lead. The shift to copper has allowed us to continue to have these vital herbivores in our ecosystem, helping generate and drive biodiversity, whilst also bringing delicious venison to your plate.


The Estate has four acres of photovoltaic panels producing 900,000 kilowatt hours of solar energy, feeding directly into the grid. This is equivalent to all the electricity used by businesses and houses on Knepp Castle Estate. Several of our larger business properties receive their energy directly from photovoltaic panels on their roofs. Our butchery has a dedicated 74.52kw solar array to reduce any direct running costs from any mains supply.


Our free-roaming animals live outside all year round in natural herds, so fresh meat is only available for us seasonally – at the end of summer and before winter begins. Freezing therefore plays an essential role in allowing us to store our meat and distribute it all year round. However, recent studies have shown that chemicals used in cooling systems including fridges and freezers are one of the highest contributors to greenhouse gases. Using the very latest technology we have replaced standard refrigerants that have global warming potential (GWP) values of 600-4000 and ozone depleting potential (ODP) values of 0.02-10 with carbon dioxide, which has the lowest available GWP value (1) and no ODP value at all. Throughout 2021 we have developed systems with our cooling experts that will enable us to harvest the thermodynamic properties for all our hot water within the butchery.

Our 12+ Policy

Knepp Wildland Safaris and campsite are all about the quiet and patient observation of nature.

Some of the species we are likely to encounter are shy or can be frightened by loud noises or sudden movements. Our campsite with open-air fire-pits, wood-burning stoves and an on-site pond is unsuitable for small children.

For this reason, our safaris, holiday cottages and campsite are suitable only for children of 12 and over.
