Production of compost from marine waste: evaluation of the product for use in ecological agriculture

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

“…Moisture content was maintained at above 50%. The pH of the obtained compost was 7.55, which is similar to the pH values of compost obtained by other authors [7,9,[13][14][15][16][17]. The pH of the extract obtained from the compost was 8.18.…”

“…Straw [13,15], bark [1,14,16], sawdust [this study , 16], and green wastes [this study , 7, 17] are examples of materials that are the most often added to the composting mixtures of algae as bulking agents.…”

“…Few researchers have been dealing with controlled composting of algae. These are of the opinion that various composting technologies for algae stabilization can be used, for example piles [1,7,11,12,[13][14][15][16]30], which can be loaded with up to 25 tons of algae [16] and can have a size of, for example, 6×2×1.5 m [14]. It is benefi cial to create piles from algal biomass near the place of their discharge [14].…”

It is benefi cial to create piles from algal biomass near the place of their discharge [14]. In a review paper, Han et al (2014) emphasize that although composting has been successfully used on a pilot scale to manage algae waste removed from eutrophied water environments, and the compost product has been applied as a fertilizer, clear guidelines for full-scale algae composting are not yet available.…”

Algal compost – toward sustainable fertilization

“…In the case of seaweed composting, several authors applied bulking agent to their composting mixtures, for example, sawdust (Mazé et al 1993, Eyras et al 1998, straw (Cuomo et al 1995, Wosnitza andBarrantes 2005), bark (Mazé et al 1993, López-Mosquera et al 2011, Illera-Vives et al 2013, and wood chips (Eyras et al 2008).…”
