“…In the light of Directive 2008/98/EC, which gives an adding value to wastes by means of their integrated management, digestate addition to soil is considered an appropriate option, with multiple benefits for agriculture and environment by reducing the use of mineral fertilisers (Zhang et al, 2015). However, applications of biogas digestates and their impacts on the environment and human health are still unexplored 3 and the effectiveness of digestate as organic amendment and fertilizer is still under debate (Nkoa, 2014).…”

“…CO 2 can be used for power-to-gas solutions (Section 3.4.3. ), as a carbon source for chemical production (methane, methanol, polyoxymethylene) [185,186] or to enrich CO 2 concentrations in greenhouses to increase vegetable yields [187,188]. CO 2 sequestration is an integral part of bioenergy with carbon capture and storage, one of the key negative emission technologies suggested to limit global warming to 1.5 • C [189,190].…”

“…Even though the use of heat has increased in Germany in recent years as a result of stricter regulations, currently only about 56% of the external heat is utilized [11]. Heat usage can contribute to many processes within the bioeconomy, such as barn and greenhouse heating, beer brewing, drying of cereals and digestate, aquaponics in fish production food processing industry or biorefinery processes [188,[220][221][222]. Excess heat can also be used for thermal pretreatment of feedstocks to enhance methane yields and thus improve the energy balance [156,159].…”

“…LCA has become an important decision-making tool for environmental management and product design worldwide and has been gradually applied to ecological industry or circular economy development and clean production (ISO 2006). Zhang et al (2015) assessed the CEMIPB with LCA and proposed corresponding energy saving and emission reduction recommendations using scenario analysis. Fan et al (2018) used LCA to analyze the CEMIPB with different industrial chain lengths in Fujian Province and pointed out that the best ecological and economic benefits can only be achieved by a reasonable plan for the length of the integration of planting and breeding industrial chain.…”
