Vitamin B12 bioaccumulation in Chlorella vulgaris grown on food waste-derived anaerobic digestate

Algal Research, 2023
Anaerobic digestion plays a pivotal role in the modern circular economy, as it offers a sustainable solution for converting organic waste into biogas (methane). It also results in a nutrient-rich liquid stream, referred to as digestate. This digestate is

Assessment of digestates prepared from maize, legumes, and their mixed culture as soil amendments: Effects on plant biomass and soil properties

Frontiers in Plant Science, 2022
Digestate prepared from anaerobic digestion can be used as a fertilizer, as it contains ample amounts of plant nutrients, mainly nitrogen, phosphorous, and potassium.

Using Digestate Compost as a Substrate for Anaerobic Digestion [PDF]

Chemical Engineering & Technology, 2018
AbstractAnaerobic digestion (AD) of separately collected biowaste is an ecologically and economically interesting waste treatment technology due to the production of utilizable biogas and coeval reduction of waste mass fractions. The combination of AD with subsequent composting leads to a higher degree of overall biowaste carbon utilization compared to
