About Assea Bioenergy & Biosoils

ASSEA Bioenergy & Biosoils transforms marine plant waste and biowaste into high-quality organic compost and biosoils. Based on Kos Island, we recycle Posidonia oceanica seaweed and other biodegradable materials through controlled aerobic composting, creating natural, peat-free, chemical-free products that support soil health and plant vitality. Thanks to our many years of experience and expertise, we produce Bio Compost ASSEA and BioSoil ASSEA, natural products that enhance soil structure, aeration, nutrient absorption, and plant resistance. We work with farmers, nurseries, garden centers, municipalities, hotels, and eco-conscious individuals seeking reliable, natural soil solutions. Our approach is rooted in circular economy principles: we collect, recycle, and return organic matter to the earth, thereby closing the loop between the sea and soil. ASSEA holds a national innovation certificate and has been recognized as an EU FLAG good practice for sustainable coastal management. Every product reflects our commitment to sustainability, responsibility, and soil health.
