“…Ammonia was one of the most important gases reduced by supplementation, and in agreement with several studies, reducing protein content in feed is the most important mitigation option to improve sustainability of animal production (NRC, 2012;Snyder et al, 2014). In a recent LCA study, De Vries et al (2015) suggested that mitigation actions such as segregation of urine and feces inside housing, addition of zeolite to solid manure, and sealed storage in integrated manure management systems reduced ammonia and methane emissions.…”

Livestock production has a variety of environmental impacts such as greenhouse gas emissions, water pollution, acidification, and primary energy consumption. The demand for livestock products is expected to grow substantially, creating even more environmental pressure. The use of specialty feed ingredients (SFI) such as supplemented AA and phytase can reduce nutrient input into the system without compromising productivity and consequently can reduce emissions. The global change impact of using SFI in pig and broiler production systems in Europe and North and South America was studied. A life cycle assessment according to international standards (ISO 14040/44) analyzed contributions from producing SFI and animals to global change. Three different alternatives were analyzed. In addition, partial sensitivity analysis was conducted using 5 scenarios for each region for both production systems. Specialty feed ingredient supplementation in pig and broiler diets reduced greenhouse gas emissions (cradle to farm gate) by 56% and 54% in Europe, 17% and 15% in North America, and 33% and 19% in South America, respectively, compared to an unsupplemented diet. A total of 136 Mt CO 2 equivalent (CO 2 eq) was saved in 2012, rising to 146 Mt CO 2 eq in 2050 on the basis of United Nations population projections. Considerable benefits of supplementation with SFI were apparent in European and South American diets when direct land use change was considered because of the reduced demand for soybean meal. The eutrophication potential of unsupplemented diets was reduced by up to 35% in pig and 49% in broiler production systems compared to supplemented alternatives. The acidification potential of supplemented strategies was reduced by up to 30% in pig and 79% in broiler production systems. The primary energy demand was similar in all alternatives, and this could be an area where the SFI industry can improve. Overall, SFI supplementation substantially reduced the global warming, eutrophication, and acidification potentials in all regions studied.

“…For the IS, we considered production and management of liquid dairy cattle manure applied to grass and maize, solid dairy cattle manure, including straw as bedding material, applied to grass, and liquid pig manure applied to wheat, all under North West European (EU) conditions with sandy and clay soils. For further details also see De Vries et al (2015).…”

“…A quantification of the N, P, and C losses and the environmental impacts of the designed strategies is described in detail in De Vries et al (2015). In the future, IS should be further developed taking other stakeholders into consideration, such as animals, farmers (costs), and technology developers (Bos et al, 2009).…”

“…Taking into account the long-term needs to reduce environmental impact, we established a goal to achieve a reduction of at least 100% 1 for CC and FFD impact, and at least 75% for all other environmental impact categories expressed per ton of excreted urine and feces as compared with current manure management in NW EU (De Vries et al, 2015). 1 Reductions of more than 100% indicate a net mitigation of emissions or a net production of energy.…”

“…Residues from livestock husbandry are abundant and common feedstocks in biogas production [72][73][74][75]. Biogas production from liquid and solid manure does not only contribute to energy supply, but is also an essential measure of integrated manure management strategies to reduce environmental impacts [76,77]. Methane yields depend mainly on animal species [78,79] and further on their type of use, sex, age and diets [80][81][82].…”

The Future Agricultural Biogas Plant in Germany: A Vision

After nearly two decades of subsidized and energy crop-oriented development, agricultural biogas production in Germany is standing at a crossroads. Fundamental challenges need to be met. In this article we sketch a vision of a future agricultural biogas plant that is an integral part of the circular bioeconomy and works mainly on the base of residues. It is flexible with regard to feedstocks, digester operation, microbial communities and biogas output. It is modular in design and its operation is knowledge-based, information-driven and largely automated. It will be competitive with fossil energies and other renewable energies, profitable for farmers and plant operators and favorable for the national economy. In this paper we discuss the required contribution of research to achieve these aims.
