The mixing and packaging of chemical products is one of the most critical phases within the chemical and process industry. Whether in solid or liquid products, incorrect execution can compromise the quality of the final product, the safety of workers, the stability of the formulation, and even legal and environmental compliance. Therefore, more and more companies in sectors such as industrial chemicals, detergents, biocides, fertilizers, water treatment, adhesives, paints, sealants, or animal feed choose to work with specialized partners in industrial mixing and contract packaging, capable of ensuring controlled, safe, and fully traceable processes. At PRO3S, we have over 20 years of experience providing mixing, handling, and industrial packaging services for chemical products, adapting ...

Industrial micronization is one of the most advanced processes in solid processing, key to improving the quality, performance, and functionality of multiple products. From the chemical industry to human and animal food, through sectors such as detergency, biocides, or nutraceuticals, particle micronization allows achieving precision levels that directly impact the final behavior of the product. At PRO3S, as specialists in grinding, micronization, and solid processing for third parties, we know that the correct reduction of particle size is not just a technical matter but a competitive advantage for our clients.   What is micronization? Micronization is a physical process by which the particle size of a material is reduced to micrometric dimensions, usually below 100 microns, and ...

Outsourcing contract packaging has become a strategic decision for many industrial companies that want to grow with agility, maintain quality and meet regulatory requirements without increasing internal structure. Just like logistics, maintenance or certain manufacturing steps, industrial packaging outsourcing allows manufacturers to focus on what truly creates value (R&D, formulation, sales and market development) while a specialized partner takes care of a critical point: preparing the final product so it reaches the customer in a commercial, safe and compliant format. At PRO3S, we operate as a trusted industrial partner for contract packaging of solid products (and complementary steps such as mixing, screening, milling or granulation), serving sectors such as chemicals, ...

In solids processing, screening and sieving are both particle size classification operations that are often conflated. However, they are not the same: they differ in purpose, size range, process stage, equipment type, and control stringency. At PRO3S we integrate both techniques on certified lines for human food, animal feed, chemicals, detergents, and biocides, ensuring full traceability and regulatory compliance.   What is screening? Screening uses large-opening meshes/screens to retain coarse particles or foreign bodies at early process stages (raw-material preparation, pre-mixing, or pre-milling). Operational features Goal: remove oversize, lumps, plastics, fibers, stones, or unwanted fragments. Typical range: > 1–2 mm (can go down to hundreds of microns ...

In solids processing, industrial screening is the unit operation that classifies and cleans particles using meshes with defined apertures. Its purpose is twofold: Ensure a particle size distribution within specification (D10–D90, mean size, uniformity), and Remove foreign matter (fibers, films, lumps, fine metals if integrated with magnets/special sieves) that would compromise safety, performance, and perceived quality. At PRO3S we integrate screening as a CCP/CP within HACCP where applicable (food/feed) and as a quality gate in chemicals, detergents, biocides, fertilizers, construction, plastics, or textiles. We select technology based on product behavior (flowability, abrasiveness, hygroscopicity, caking tendency): vibratory sieves for high throughputs and medium ...

At PRO3S we know sustained success is never built in isolation. Our operating model is grounded in collaboration with customers and suppliers, with a clear goal: turning outsourced processing into a real, measurable and scalable competitive advantage. To achieve this, we rely on three guiding pillars in every interaction: trust, professionalism and a service mindset. Trust: the foundation of every collaboration Trust is built through transparency, consistency and results. We work strictly as a third-party processor and protect our clients’ IP with NDAs and specific internal procedures. End-to-end visibility: 100% lot- and raw-material-level traceability. Auditable processes: a mature quality system with ISO 9001, ISO 14001, FSSC 22000 and GMP+ certifications. Data ...

In industrial manufacturing, raw-material mixing is not a formality—it’s a critical step that determines product stability, safety and performance. Poor mixing yields variability, rework and extra costs; robust mixing ensures consistent quality, scalability and efficiency. At PRO3S we design and execute tailored mixing processes for human and animal nutrition, detergency, biocides and industrial chemicals.   What defines a good mixing process Homogeneity and repeatability: uniform distribution of actives and excipients (control of CV or %RSD per specification) and lot-to-lot reproducibility. Particle-size and flow control: particle size, bulk density and flowability fit for the next operation (sieving, dosing, packaging). Addition sequence: correct order ...

A robust equipment maintenance and prevention program not only avoids downtime, it also protects people, safeguards product quality and preserves asset value. At PRO3S, maintenance is embedded into daily operations to ensure availability, precision and regulatory compliance across all lines.   Maintenance and prevention objectives Avoid critical failures that may cause accidents, non-conformities or production stops. Guarantee process accuracy and repeatability (batch quality, tolerances, calibrations). Comply with EHS regulations (ISO 9001, ISO 14001, GMP+, FSSC 22000). Extend equipment lifecycle, reducing total cost of ownership (TCO). Optimize OEE (Availability, Performance, Quality) through planned stops and standard times.   Maintenance strategy: ...

Efficient Outsourcing: Logistics and Work Planning at PRO3S In an increasingly competitive and dynamic business environment, many companies choose to outsource services to focus on their core business. However, successful outsourcing is not only about delegating tasks; it depends on how logistics and work planning are managed. At PRO3S, we rely on robust organization to ensure efficiency, on-time quality delivery, and customer satisfaction. Logistics at PRO3S Logistics at PRO3S goes far beyond transport or storage; it’s about coordinating resources, processes, and timing so that contracted services are executed effectively. Key aspects include: Workforce management: assigning the right person based on skills and availability. Tools & technology enablement: ensuring all ...
