Organic Byproducts and Waste in Dairy and Meat Companies: Legislation and Solutions Spain-Europe 2025

Spanish dairy and meat companies face an increasingly complex legislative landscape in managing organic byproducts, with current regulations imposing fines that can reach €600,000 for serious violations. Compliance with the SANDACH Regulation and the Waste Framework Directive represents not only a legal obligation but also a business opportunity that can transform waste management costs into additional revenue sources for SMEs in the sector.

The current regulations under Royal Decree 1528/2012 establish mandatory documentation systems and traceability requirements that particularly affect small dairies, local slaughterhouses, and processing companies. While large corporations have specialized departments, SMEs must navigate this complex regulatory framework with limited resources, facing compliance costs representing between 10-15% of their initial startup budget.

The European landscape of dairy and meat waste is experiencing a fundamental transformation toward the circular economy, with emerging markets for byproducts reaching €150 billion globally. From whey used in functional ingredients to meat waste converted into biodiesel and pet food, valorization opportunities are redefining waste management as a viable commercial strategy.

SANDACH legislative framework and European regulations for organic waste

The Regulation (EC) No 1069/2009, known as SANDACH, establishes fundamental sanitary rules for animal byproducts not intended for human consumption. Category III, specifically relevant for non-hazardous meat waste, includes materials such as fats, blood, bones, and hides from animals fit for human consumption but destined for other uses for commercial reasons.

The Spanish implementation through Royal Decree 1528/2012 maintains the established requirements for animal byproduct management. This regulation establishes mandatory documentation systems and traceability requirements that include detailed movement recording and documentation capabilities for commercial transactions.

The differences between Spanish implementation and other European countries are notable. Spain maintains national SANDACH registers (establishment and movement) that exceed EU minimum requirements and requires separate registration of transport operators, while other European countries allow greater flexibility in these aspects.

Waste Framework Directive applied to the food sector

The Directive 2008/98/EC on waste establishes the fundamental framework for waste management in the EU. For the dairy and meat sector, this means implementing waste management hierarchies prioritizing prevention, reuse, recycling, and energy recovery before disposal.

Extended Producer Responsibility (EPR) schemes are being gradually developed, requiring companies to assume greater financial and organizational responsibility for managing waste from their products throughout their entire lifecycle.

Specific obligations by company size

Large companies must comply with complete registration and approval requirements under Articles 23-24 SANDACH, complete HACCP implementation, annual reporting obligations, professional liability insurance requirements, and appointment of dedicated compliance officers.

For SMEs, there are simplified procedures available under national derogations, risk-based inspection frequencies, shared service agreements permitted for transport, and reduced documentation requirements for internal movements.

Microenterprises have a 24-month compliance transition period (versus 18 months for large operators), exemption from certain HACCP requirements, simplified registration procedures, and option to designate authorized representatives.

Specific management of dairy whey according to European regulations

Types of whey and regulatory characteristics

Sweet whey (pH 5.6-6.6) from hard cheese production with rennet or enzymes, presents 70-75% lactose content and is primarily destined for bakery products, confectionery, and beverages. Its management is regulated by Article 10(h) of SANDACH, which classifies centrifuge or separator sludge from milk processing as Category III.

Acid whey (pH 4.3-5.1), a byproduct of soft cheeses or acid casein through microbial fermentation, presents greater processing challenges due to its lower pH and higher mineral content. Treatment obligations before discharge require treatment systems with costs of €1.21/m³ of treated wastewater.

Demineralized whey, with 25%, 50%, or 90% of minerals removed, finds its main application in infant formula and specialized nutritional products, complying with strict traceability requirements under the TRACES system for intra-European trade.

Compliance costs vs fines for dairy SMEs

Basic treatment systems require investments of €50,000-150,000 for small facilities, while advanced processing can reach €200,000-500,000 for valorization equipment. Annual operational compliance costs range between €10,000-30,000 for documentation and testing.

The fine structure under Spanish Food Waste Law can reach €500,000 for improper discharge, while EU Water Framework violations typically result in fines of €10,000-100,000. Loss of export licenses can represent revenue losses of 20-50% for violating facilities.

Whey valorization opportunities

The global market for dairy nutritional and nutraceutical ingredients is estimated at several billion dollars, with sustained growth projections. Whey protein concentrates (WPC-80) are traded at €3,500-4,500/MT, while whey protein isolates (WPI) can reach prices of €8,500-18,700/MT depending on market conditions.

Animal feed applications offer direct liquid whey at €0.05-0.08/liter, dry whey at €800-1,200/MT for feed grade, and high-protein concentrates at €1,500-2,500/MT, leveraging strong growth in the European animal nutrition sector.

SANDACH Category III meat waste: definitions and mandatory management

Exact definition according to current regulations

Category III materials according to Article 10 of the SANDACH Regulation include parts of slaughtered animals fit for human consumption but not intended for consumption, carcasses or body parts of slaughtered animals without signs of infectious disease, and animal-origin products that no longer meet quality specifications but pose no risk to public health.

Specific materials comprise animal fats suitable for technical uses, blood from animals fit for human consumption used in feed or fertilizer production, bones without nervous tissue processed into bone meal or gelatin, and hides and skins from approved animals destined for leather production or technical applications.
