Composting of waste algae: A review

Co-Composting of Algae and Effect of the Compost on Germination and Growth of Lepidium sativum

“…), and spent mushroom substrate, or SMS (2.5 kg wet biomass (w.m.) -humidity 65.3%), in order to obtain an appropriate C:N ratio (25:1-30:1 [4]). …”

“…Before decomposition can set in, the composted materials must have an appropriate C/N ratio that permits microbial activity, which should be between 25:1 and 30:1 [4]. The content of C and N in the composting mixture with a humidity of 69.7% was 45.2% and 1.84% (dry mass), respectively.…”

“…eutrophication and resultant algal blooms, it is necessary to examine the methods of removing and processing algal biomass waste and to fi nd a method for its cost-effective utilization in order to obtain value-added products [3,4]. Eutrophication problems occur from time to time in many areas of Europe -for example the North Sea; the Danish, Norwegian, French (Normandy and Brittany), British, and Portuguese coasts; the German Bight, and the Baltic Sea.…”

The Environmental Biorefinery: Using Microalgae to Remediate Wastewater, a Win-Win Paradigm

“…The wet biomass can also be used as a feedstock for composting. Composting has been successfully performed at the pilot-scale for macroalgae [90] and is envisaged to be as equally successful with microalgal biomass. Indeed green seaweed compost could effectively increase the growth and water resistance of tomato plants [91].…”

Zeewier en natuurlijk kapitaal : kansen voor een biobased economy

“…Hanjra en Qureshi (2010) stellen dat efficiënt gebruik gemaakt kan worden van nutriënten als de productie van zeewier en zeedieren gecombineerd wordt met de traditionele landbouw. Toevoeging van zeewier aan ander organisch afval resulteert in een beter composteerbaar product, en draagt zo bij aan de mogelijkheid nutriënten te hergebruiken (Han et al, 2014). Bij visteelt op zee wordt een deel van het voer niet door de vissen opgenomen en is er daarom sprake van uitspoeling van nutriënten.…”
