Impact of Climate Change on Gelatin Production in the European Union

Introduction

Gelatin is a collagen-based protein obtained by boiling animal skins, bones, and connective tissuesessfeed.com. In the European Union (EU), gelatin production relies mainly on porcine (pig) and bovine (cattle) sources, with a small share from fish byproducts. Porcine gelatin makes up about 58% of EU volume and bovine about 42%, while fish gelatin remains under 1% – used in niche applications like halal/kosher productsedepot.wur.nledepot.wur.nl. As a byproduct of the meat and fisheries industries, gelatin exemplifies the circular economy by "upcycling" waste tissues into valuable productsworldbiomarketinsights.com. However, climate change is introducing new challenges across the gelatin supply chain – from the health of livestock and fish resources to processing costs and regulatory pressures. This report examines how a changing climate affects gelatin production in Europe, including impacts on animals, raw material availability, energy use, economic and policy shifts, and industry adaptation strategies.

Climate Stress on Livestock and Fish

Livestock: European livestock populations (cattle and pigs) used for gelatin are increasingly stressed by climate change. Rising temperatures and heat waves directly cause heat stress in animals, reducing their feed intake, growth, and reproduction ratespmc.ncbi.nlm.nih.gov. Heat-stressed cattle and pigs eat less and gain weight more slowly, leading to smaller yields of meat, bones, and hides for gelatin. High heat and humidity also weaken immune function and promote disease outbreakspmc.ncbi.nlm.nih.govpmc.ncbi.nlm.nih.gov. For example, a hotter climate can expand the range or season of parasites and pathogens, raising incidences of livestock illnesspmc.ncbi.nlm.nih.gov. The combined stresses of decreased feed availability, drought-related water scarcity, and more frequent diseases are projected to negatively impact livestock productivity, and can even increase mortality during extreme eventspmc.ncbi.nlm.nih.gov. In southern Europe, droughts already reduce pasture and fodder crops, forcing farmers to thin herds. Sudden events like heatwaves, wildfires, floods, or storms can cause mass animal fatalities (e.g. thousands of poultry or cattle lost in a single disaster)pmc.ncbi.nlm.nih.govpmc.ncbi.nlm.nih.gov. While warmer winters might slightly ease cold stress in northern areas, overall the net effects on EU livestock are expected to be harmful, threatening the steady supply of animal byproducts for gelatinpmc.ncbi.nlm.nih.gov.

Fish: Climate change is also disrupting fish populations that supply fish gelatin (from skins and bones of species like cod, haddock, or warm-water fish). Warming ocean temperatures, shifting currents, and ocean acidification alter marine ecosystems and fish reproduction. Even well-managed European fisheries are likely to suffer long-term declines under climate trendsfrontiersin.org. Fish stocks are migrating northward or into deeper waters to find cooler conditions, making catches unpredictable. For instance, the decline of Atlantic cod in European waters has been exacerbated by climate-driven shifts in plankton production that underpin the food chaincakex.org. As a result, fish available for processing (and their residual skins/bones for gelatin) may become scarcer or of smaller size. Aquaculture (fish farming) faces climate-related challenges too – higher water temperatures and disease risks in fish farms, and potential feed shortages (since aquaculture feed often depends on wild fish or crop inputs). While the EU's fisheries might handle short-term climate variability with adaptive management, persistent warming trends and more frequent marine heatwaves threaten long-run resiliencefrontiersin.org. In summary, climate change imposes physiological stress, disease burdens, and habitat disruptions on the very livestock and fish from which gelatin is derived, undermining the foundation of gelatin production.

Raw Material Availability and Quality

Climate-induced impacts on animals translate into availability and quality issues for gelatin's raw materials. Gelatin manufacturers depend on a consistent supply of collagen-rich inputs (like pig skins, cattle hides, and fish skins/bones). With climate change, these inputs are becoming more variable. Prolonged droughts can decimate pastures and feed crops, compelling farmers to cull animals early. This creates short-term spikes in slaughter byproducts followed by longer-term shortages as herds are diminishednpr.org. For example, a severe drought might prompt an early slaughter surge (temporarily flooding the market with skins and bones), but subsequent herd reduction means fewer animals to process in following years – tightening gelatin raw material supply. On the other hand, extreme weather events can abruptly wipe out livestock or fish stocks, as seen when floods or storms cause high animal mortalitypmc.ncbi.nlm.nih.gov. Such sudden losses remove significant volumes of potential raw material overnight.

Quality considerations are also emerging. Stressed or malnourished animals tend to have different carcass characteristics. Heat stress in livestock can alter the composition of muscle and connective tissue – studies note changes in meat color and water-holding capacity under heat stresspmc.ncbi.nlm.nih.gov. These changes hint that collagen quality from stressed animals might be affected (e.g. lower collagen content or altered properties), potentially influencing gelatin yield or gel strength. Increased disease prevalence can impact raw material quality as well; for instance, skin diseases or parasite infestations (which may become more common with warmer, more humid conditions) could damage hides and skins before processing. In fisheries, warmer waters often mean smaller fish and shifts in species – fish in warmer conditions have shown reduced average body weightssciencedaily.com. Smaller fish or different species might yield gelatin with different gel strengths or gelling temperatures, requiring processing adjustments. Moreover, if raw materials have to be transported from farther away (due to local shortages), there's a greater chance of degradation in transit, especially in hot weather. Maintaining cold chains for perishable byproducts becomes more crucial and challenging as ambient temperatures rise.

Another issue is regulatory or health-imposed supply constraints. As climate change can facilitate the spread of animal diseases, authorities might impose culling or trade bans to contain outbreaks (for example, culling pigs during an African swine fever outbreak, or restricting bovine products during a disease epidemic). Such measures directly cut into the available pool of animal byproducts. Feed quality is another indirect factor – climate-induced nutrient deficiencies in feed crops could lead to animals with poorer condition and lower collagen quality. All these factors mean gelatin producers face a less predictable and potentially lower-quality input stream. The need for locally sourced raw materials is becoming even more important, as noted by industry, to avoid heavy reliance on imports that might face climate or trade disruptionsanimaltaskforce.euanimaltaskforce.eu. In summary, climate change threatens to reduce and destabilize the supply of high-quality raw collagen inputs in Europe, forcing the gelatin industry to seek alternatives or adjust processing methods to maintain product consistency.

Energy Demands and Processing Costs

Gelatin manufacturing is energy-intensive, requiring substantial heat for collagen extraction and electricity for grinding, chilling, and drying. A typical gelatin plant consumes on the order of 22 GJ of heat and 1,100+ kWh of electricity per ton of gelatin producedaimspress.com. Climate change impacts this facet in multiple ways. Firstly, rising average temperatures and more frequent heatwaves increase the energy needed for cooling and refrigeration in gelatin processing. Gelatin raw materials and intermediate products must be kept cool to prevent spoilage (especially in warm weather when bacteria grow faster). As ambient temperatures climb, factories must run chillers and cold rooms harder and longer. External data show that extreme heat drives up cooling electricity demand significantlyiea.org, and similar effects are likely in food processing plants. For gelatin producers, a hot summer could mean higher electricity usage to maintain stable process temperatures and air-conditioned environments for worker safety and product quality.

Secondly, climate change can indirectly raise energy costs. Policies aimed at curbing climate change – such as carbon pricing, emissions trading, or higher taxes on fossil fuels – increase the cost of energy derived from those fuels. Since gelatin plants often use natural gas or fuel oil for boilers and electricity from the grid, any carbon price or green energy mandate in the EU can make heating and power more expensive. Additionally, climate-driven geopolitical or economic disruptions can affect energy supply. For example, a severe drought might reduce hydropower generation, or global conflicts exacerbated by climate stress can disrupt fuel supply lines. In late 2023, Europe faced a scenario of rising energy prices and shipping delays which was projected to drive up gelatin production costs and market priceschemanalyst.com. In one analysis, industry observers noted that higher oil and gas prices (whether from conflict or carbon policy) feed into increased manufacturing and transport costs, ultimately pushing gelatin prices upwardchemanalyst.com.

Moreover, extreme weather events threaten energy infrastructure reliability. Heatwaves can strain the electrical grid (risking outages or peak pricing), while storms and floods can damage power plants or transportation routes. A power outage or fuel shortage at a gelatin facility could halt production or require backup generators, both of which add expense. Water scarcity is another linked concern – gelatin processing needs large volumes of water, and treating or recycling water requires energy. In drought conditions, plants might invest in water recycling systems (as some have begun to do) to secure water supplydarlingii.com, which could slightly increase energy usage initially but improve long-term resilience. Overall, climate change tends to escalate the energy demand and operational costs for gelatin manufacturing in the EU, through higher cooling needs, pricier and less reliable energy supplies, and the necessity of investing in more robust infrastructure.

Regulatory and Economic Shifts

Alongside direct physical impacts, climate change is driving regulatory and market changes that affect gelatin production in Europe. The EU has committed to ambitious climate and sustainability goals under the European Green Deal. Initiatives like the Farm to Fork strategy and the proposed Framework for Sustainable Food Systems aim to reduce greenhouse emissions, pollution, and waste in agriculture and food processing. While the gelatin industry supports these objectives, it recognizes that new environmental regulations will have ripple effects on farmers and the meat industryanimaltaskforce.eu. For instance, policies to cut methane emissions could require livestock producers to change animal diets, invest in waste management, or even shrink herd sizes. A reduction in EU cattle or pig numbers (to meet climate targets or due to high compliance costs) would directly reduce the availability of domestic gelatin raw materials. Industry representatives have raised concerns that overly stringent measures could put pressure on raw material supply, possibly causing businesses to relocate outside Europe or increase reliance on imported gelatin and collagenanimaltaskforce.eu. Ensuring a steady local supply of bones and skins is crucial, so any policy that impacts slaughter rates or byproduct handling is significant for gelatin makers.

Another regulatory aspect is animal welfare and health measures that intersect with climate. As climate change heightens disease outbreaks, the EU may tighten regulations on animal traceability, health monitoring, and the processing of animal byproducts to ensure safety. Gelatin producers already adhere to strict safety (e.g. preventing BSE contamination), and climate-related disease risks could lead to additional testing or restrictions (for example, rules on using materials from regions under quarantine). Compliance with such rules can raise production costs or limit sourcing options.

Economically, climate change can alter commodity prices and consumer behavior. Droughts and heat negatively affect yields of feed grains (like corn and soy), driving up feed costs and consequently the cost of raising livestock. Over time this can make meat (and thus byproducts) more expensive. The availability of crops for feed is projected to drop under climate scenarios, which could indirectly reduce pig and poultry production in Europecolab.ws. If farmers face poor harvests, they may produce fewer animals, again shrinking gelatin inputs. On the demand side, European consumers are becoming more environmentally conscious. There is a gradual shift in preferences – some consumers reduce red meat consumption or seek plant-based alternatives for ethical and climate reasons. If these trends continue, the meat processing volume in Europe could decline, affecting gelatin byproduct supply but also potentially increasing interest in gelatin alternatives.

Additionally, climate change is prompting discussions on product sustainability which can influence gelatin markets. For example, food and pharma companies that use gelatin might start asking for proof of sustainable sourcing or a lower carbon footprint. The EU could introduce labeling or sustainability standards that gelatin suppliers must meet (similar to how the Marine Stewardship Council certifies sustainable fish gelatin sourcesessfeed.com). Economic instruments like carbon credits or subsidies for green energy could also come into play, encouraging gelatin factories to adopt cleaner technologies. In sum, Europe's climate policies and the evolving economic landscape are pushing the gelatin sector toward more sustainable practices, but also creating uncertainties. The industry must navigate possible raw material shortages due to climate policies, increased production costs due to environmental compliance, and shifting market demand – all while staying competitive with global gelatin producers.

Sustainability Strategies and Adaptation by the Industry

Facing these challenges, the gelatin industry in the EU is actively pursuing adaptation and sustainability strategies to ensure long-term viability. Key approaches include:

• Circular Economy Practices: Gelatin production inherently supports a circular economy by valorizing slaughterhouse and fish processing co-products that would otherwise go to waste. This role is being reinforced and expanded. 100% of gelatin's animal raw materials are co-products – no animal is ever raised or killed just for gelatinanimaltaskforce.eu. Manufacturers emphasize that their products upcycle waste into useful inputs for food, pharmaceuticals, and other industries. By doing so, the industry reduces overall waste and the environmental burden of disposing of animal byproducts. Some companies are exploring novel feedstocks within this circular paradigm, such as reclaiming gelatin from leather off-cuts or other collagen-rich waste streams that are currently underutilizedworldbiomarketinsights.comworldbiomarketinsights.com. Using more waste from leather tanning, seafood processing, and poultry (e.g. chicken feet rich in collagen) can diversify sources and buffer against shortages in any one sector. One recent analysis noted that about half of gelatin-rich hides from leather manufacturing are discarded, representing a "huge pool of potential inputs" for gelatin if proper collection and processing methods are appliedworldbiomarketinsights.com.

• Diversifying and Securing Raw Materials: To adapt to fluctuating supply, gelatin producers are seeking multiple raw material streams. This includes maintaining a balance between porcine and bovine sources and increasing the use of fish gelatin where feasible. Fish gelatin, while only a small fraction of output now, offers an alternative especially in regions or markets where pork or beef supply is constrained or where religious/ethical factors demand non-mammalian gelatinworldbiomarketinsights.com. Research projects (such as the EU's EcoeFISHent initiativefoodtimes.eu) are investigating extraction of collagen from new fish parts and species to broaden marine sources. Additionally, the industry is closely watching the field of insect protein or other novel sources as a potential future collagen supply (still in early R&D). At the farm level, adaptation includes breeding or using heat-tolerant livestock breeds that can better cope with a warmer climate. For example, introducing cattle breeds with higher heat tolerance (like certain zebu cattle) could maintain production under high temperatures, though companies must then adjust to any differences in the collagen properties (since heat-adapted breeds may have slightly different hide and bone characteristics)pmc.ncbi.nlm.nih.gov. Ensuring raw material supply also means working with farmers and slaughterhouses on climate resilience – e.g. encouraging improved animal health programs to reduce disease losses, and supporting feed management strategies during drought.

• Energy Efficiency and Emissions Reduction: Gelatin manufacturers are investing in energy-saving technologies and renewable energy to counter rising costs and meet climate goals. Several European gelatin plants have begun on-site renewable power generation – for instance, a major gelatin plant in Girona, Spain installed solar panels in 2023 that produced 231 MWh of renewable electricity in that yeardarlingii.com. Companies are upgrading equipment (boilers, dryers, refrigeration units) to more efficient models and implementing heat recovery systems to reuse waste heat from one process to another. Efforts to cut water usage also contribute to energy savings; for example, a facility in France reduced its water consumption by 20% by recycling cooling water into the processdarlingii.com, which indirectly lowers the energy needed for fresh water pumping and treatment. The industry's largest players have set emission reduction targets – Darling Ingredients (parent of Rousselot) aims to cut its Scope 1 and 2 greenhouse gas emissions by 42% by 2030darlingii.com. These targets drive investments in cleaner operations (like biogas from waste or switching to green electricity). Not only do such measures mitigate the industry's climate footprint, but they also build resilience against energy price volatility.

• Innovation and Alternative Products: Acknowledging the long-term trends, gelatin and collagen companies are innovating with alternative production methods. One exciting development is the rise of lab-grown (fermentation-based) gelatin that does not require animal farming. Companies like Geltor (in the US) have pioneered techniques to produce collagen proteins by genetically engineered microbesworldbiomarketinsights.com. These microbes "brew" gelatin in fermentation tanks, yielding a product that is molecularly identical to animal gelatin but is animal-free. European producers are monitoring and collaborating on such technologies, as they could provide a climate-independent source of gelatin in the future (no livestock needed, and potentially powered by renewable energy). While still a nascent field, fermentation-derived gelatin might become a viable supplement or complement to traditional gelatin, especially if climate change severely limits livestock outputs decades from now. In the meantime, food scientists are also working on plant-based gelling agents (like agar, pectin, or modified starches) as partial replacements in certain applications, to reduce demand pressure on animal gelatin. The gelatin industry is adapting by finding specialized uses where gelatin's unique properties are irreplaceable and improving those properties (for example, developing fish gelatin variants with higher gel strength or melting point to match mammalian gelatin performanceedepot.wur.nledepot.wur.nl).

• Collaboration and Policy Engagement: The industry is actively engaging with policymakers and other sectors to manage climate challenges. European gelatin manufacturers through their association (GME) collaborate with the meat and fish industries to ensure sustainable sourcing standards, support animal welfare improvements, and maintain transparency in the supply chaindarlingii.com. Gelatin producers support certifications like the Marine Stewardship Council for sustainable fish sourcing and are part of discussions on the EU's sustainable food system frameworkanimaltaskforce.eu. By providing data and scientific input, the industry hopes to inform climate-related regulations so that they achieve environmental goals without unintentionally causing raw material shortages or simply shifting environmental impacts overseasanimaltaskforce.eu. Economically, companies are diversifying their markets and developing higher-value gelatin and collagen products (for medical or technical uses) which can justify the investments in sustainability. This adds economic resilience, making the gelatin sector less vulnerable to commodity price swings and giving it more capacity to invest in climate adaptation measures.

Through these combined strategies, the EU gelatin industry is striving to future-proof its operations against climate change. Using every available byproduct, investing in efficient tech, and exploring new sources all increase resilience. While there are limits – gelatin ultimately depends on the larger livestock and fish sectors – these adaptation efforts can help ensure that gelatin production remains viable and sustainable even as the climate continues to change.

Conclusion

Climate change poses a multifaceted challenge to gelatin production in Europe. It undermines the health and productivity of the livestock and fish that provide gelatin's raw materials, leading to issues like heat-stressed pigs and cattle, more frequent diseases, and volatile fish stocks. These biological impacts in turn threaten the availability, consistency, and quality of collagen inputs (hides, bones, skins), at times causing raw material shortages or requiring the industry to adjust to lower quality feedstock. Additionally, climate change is raising the operational costs of gelatin manufacturing by driving up energy demand for cooling and prompting higher fuel and electricity prices under both market pressures and climate policies. The regulatory environment is evolving as the EU pushes for more sustainable agriculture and food processing, which is positive for long-term climate action but necessitates careful adaptation by gelatin producers to secure raw materials and remain competitive.

Despite the challenges, the gelatin industry is actively responding with sustainability and adaptation initiatives. By embracing circular economy principles, improving energy and water efficiency, diversifying raw materials (including exploring fish and novel sources), and investing in innovation like lab-grown gelatin, the sector is enhancing its resilience. European gelatin manufacturers are aligning with the EU's climate objectives while also voicing the needs of their industry – ensuring that policy shifts are informed by science and practical considerationsanimaltaskforce.eu. Moving forward, close cooperation between farmers, fisheries, processors, and regulators will be crucial. This cooperation can support climate adaptation measures (like heat-tolerant animal breeds, sustainable feed, and robust supply chains) that benefit both primary producers and gelatin makers. In conclusion, climate change is already impacting gelatin production in the EU by stressing the supply of traditional gelatin sources and altering production economics. However, with proactive adaptation and sustainability efforts, the industry can continue to thrive and provide its valuable products, all while reducing its environmental footprint and helping build a more resilient food system.
