In this review, 3D-printing-based approaches for the fabrication of meat substitutes are explored. The global 3DP market is expected to expand to $230–550 billion USD by the end of 2025. The 3DP technology is suggested to have a significant potential to lower CO 2 emissions and lifecycle energy demands of manufacturing products. The 3D printing process involves a layer-by-layer deposition of materials (inks) to form 3D complex intricate structures. As a result, some strategies have been proposed that include dietary changes, innovative products, technological improvements, and diminutions in food wastes and losses.

Apart from the impact of GHG from meat production, ethical issues pertaining to the slaughter of animals are strong reasons to seek alternatives for livestock meat. The direct and indirect effects of livestock production include food security issues, health risks, animal welfare issues, and the loss of biodiversity. Of the total anthropogenic CH 4, N 2O, and CO 2 emissions, the livestock sector contributes 19%, 15%, and 1.35%, respectively. Beef is the most problematic of all livestock because it requires large land areas and resources. Major livestock that contribute to this threat are cattle, pigs, sheep, goats, and chickens. However, the contribution from the livestock sector to the total annual anthropogenic GHG emissions is about 14.5%. The amount and rate of climate change are mainly affected by greenhouse gas (GHG) emissions that result from energy generation (fossil fuel combustion) and non-energy emissions (agriculture, land-use changes, and livestock production). Climate change has also been projected to affect all facets of food security, which include availability, ease of access, consumption, and stability. The discernable impact of human-induced climate change include increases in temperature, the frequency of droughts, rainfall intensity, flooding, and other severe weather events. Consumer acceptance could be a significant challenge that could hinder the success of 3D-printed meat analogs.Ĭlimate change is a growing concern amongst several nations around the world. Irrespective of the materials used, perception-related challenges exist for 3D-printed food products. Apart from printer innovations (speed, precision, and productivity), rational structure of supply chain and optimization of material flow and logistic costs can improve the sustainability of 3D printing. Valuable materials derived from meat byproducts/wastes using low energy methods could reduce waste production and offset some greenhouse gas (GHG) emissions. From various insects, powders, proteins (soluble/insoluble), lipids, and fibers are produced, which-in different combinations and at optimal concentrations-can potentially result in superior meat substitutes. Despite the availability of several plants and their byproducts and some start-up ventures attempting to fabricate food products, 3D printing of meat analogues remains a challenge. The sustainability of bioprinting could be enhanced by the utilization of generic/universal components or scaffolds and optimization of cell sourcing and fabrication logistics. The impediments to bioprinting of meat are lack of food-safe substrates/materials, cost-effectiveness, and scalability.

Although skeletal muscles and skin are bioprinted for medical applications, they could be utilized as meat without the additional printing of vascular networks. These material-based approaches are analyzed from their potential environmental effects, technological viability, and consumer acceptance standpoints. For sustainable 3DP of meat substitutes, the possible materials discussed are derived from in vitro cell culture, meat byproducts/waste, insects, and plants. The emerging technology of 3D printing (3DP) has been recognized for its unprecedented capacity to fabricate food products with intricate structures and reduced material cost and energy. To mitigate the threat of climate change driven by livestock meat production, a multifaceted approach that incorporates dietary changes, innovative product development, advances in technologies, and reductions in food wastes/losses is proposed.
