Natural Fertiliser Holdings · NL BV
CACO.earth is a Netherlands-registered holding company pioneering the circular economy of calcium — transforming eggshell waste into globally patented, natural fertiliser solutions via its primary asset, Egg-Cellent Calcium.
Who We Are
CACO.earth BV is a Netherlands-registered private limited company whose mission is to build and steward businesses that restore natural mineral cycles to the soil.
Our flagship asset, Egg-Cellent Calcium, is a South African fertiliser manufacturer that recovers calcium carbonate from eggshell waste and returns it to agriculture — the circular economy in action.
We provide capital stewardship, IP governance, and global commercial development to accelerate the growth of natural fertiliser technologies across Africa and beyond.
Primary Asset
Egg-Cellent Calcium is a South African fertiliser manufacturer producing premium calcium-based agricultural inputs from eggshell waste, using a globally patented processing technology.
The business operates at the intersection of waste valorisation and precision agriculture — diverting eggshell material from landfill and returning a critical soil nutrient to the agricultural value chain.
How It Works
Our patented four-stage process transforms eggshell waste — a byproduct of the global food industry — into a precision agricultural calcium input. Each step is controlled, tested, and optimised for maximum agronomic performance.
We partner with food processors and egg producers to collect eggshell waste at source — establishing a traceable, reliable, and low-cost calcium feedstock supply chain.
Our globally patented technology transforms raw eggshells into refined calcium carbonate with engineered particle size and surface characteristics optimised for agricultural use.
Every batch undergoes rigorous testing for calcium content, purity, pH, and particle distribution. We guarantee consistency because farmers depend on it.
The finished product reaches farmers for direct soil amendment — correcting pH, supplying calcium, improving structure, and delivering measurable yield gains.
The Science
Calcium is one of agriculture's most important yet undervalued macronutrients — essential for plant cell wall integrity, root development, and nutrient transport, directly impacting yield quality and crop resilience.
Unlike quarried limestone alternatives, eggshell-derived calcium carbonate is a biogenic, low-carbon source that integrates gently with soil ecosystems without disrupting the microbial communities underpinning long-term productivity.
Calcium carbonate neutralises acidic soils, raising pH to unlock nutrients already present in the soil profile and restore microbial activity.
Calcium acts as a binding agent in soil aggregation — improving crumb structure, aeration, water retention, and drainage in clay-heavy soils.
Critical for strong cell walls, robust root tips, and the transport of other nutrients — directly impacting fruit and grain quality and marketable yield.
Eggshell-derived CaCO₃ offers a genuinely circular alternative to quarried limestone, with a substantially lower carbon footprint and embedded waste diversion value.
Corporate Structure
CACO.earth BV is incorporated in the Netherlands — a jurisdiction globally recognised for its investor-friendly corporate law, extensive tax treaty network, and position as a gateway to European capital markets.
As a holding company, CACO.earth provides strategic oversight, IP stewardship, and capital allocation to its operating subsidiaries — beginning with Egg-Cellent Calcium in South Africa.
This structure positions CACO.earth optimally for attracting European and international investment while maintaining operational proximity to its African manufacturing base. We are currently preparing for an EU-facing capital raise.
CACO.earth is preparing for a European capital raise. We are seeking aligned investors who understand the long-term value of sustainable, circular agriculture.
