In a unique in-situ process, we obtain the eggshell membrane on the same day that the egg-cracker breaks the eggs and generates the eggshell, thus preserving its qualitative properties, avoiding the decomposition of organic matter and minimising the carbon footprint as part of a fully circular economy.

So we take advantage of the sun as a source of clean and green energy.

Our branded ingredients are 100% chemical-free.
