In the fertilizer industry, every formula matters. Not all crops need the same nutrients, nor do all companies share the same logistics or commercial goals. That’s why at PRO3S, we offer customized processes for the manufacturing and packaging of solid fertilizers, adapting to the technical, legal and commercial requirements of each client. Customization in production is not just a competitive edge — it’s the key to ensuring agronomic efficacy, improving field application and optimizing invested resources. From formulations with specific micronutrients to controlled particle sizes or packaging formats adapted to distribution channels, our processes enable the creation of products perfectly aligned with real market needs. In addition, the use of segregated production ...

In the solid processing industry, the milling process is a crucial step that directly impacts the quality, functionality, and performance of the final product. Especially in sectors such as human food, animal feed, and chemicals, particle size, shape, and distribution play a key role in the product’s safety, effectiveness, and downstream processing behavior. At PRO3S, with over 20 years of experience in contract processing, we are highly aware of the importance of quality control in milling, and we apply it rigorously through specific internal systems of monitoring and traceability. This article explains why this control is key and how we implement it. What is milling and why is it critical? Milling is the process of reducing the particle size of a solid material using mechanical ...

The formulation of detergents has undergone a major transformation in recent years. Faced with growing environmental awareness from consumers, regulators and companies, the detergent sector is shifting towards more sustainable, effective and responsible products. At PRO3S, as specialists in third-party manufacturing and packaging of detergents, we are at the forefront of this transition, adopting cleaner and more environmentally respectful formulas without compromising performance. Sustainability as a core axis of innovation Current trends in detergent formulation revolve around three key axes: Reducing environmental impact: aiming to minimise the product's ecological footprint throughout its lifecycle—from raw material sourcing to use and disposal. Replacing traditional ...

In the industry of handling and packaging solid products, continuous innovation is key to ensuring more efficient, safer, and sustainable processes. At PRO3S, we’ve been committed for years to continuously improving our facilities, machinery, and work methodologies to offer top-quality third-party services tailored to the needs of each client and sector.

Solid Product Packaging: A Critical Operation The packaging of powdered or granulated ...

In the food industry, the safety and quality of final products largely depend on rigorous controls throughout the production chain. One of the key processes is sieving, which plays a crucial role in ensuring food safety. At PRO3S, specialists in solid processing and third-party manufacturing, we fully understand its importance and integrate it as a critical step in our workflows. Sieving: more than particle separation Sieving classifies solids based on particle size using specific mesh sizes. It removes foreign bodies, clumps or inconsistent particles to achieve a homogeneous product that meets quality standards. In the human and animal food sectors, sieving directly contributes to food safety by preventing contamination and ensuring product integrity. Hazard Analysis and Critical ...

Feed Additives: Essential Complements for Safe Animal Feeding The term "food additive" often carries negative connotations; however, in livestock industries, feed additives play a crucial role not only in nutrition but also in ensuring global food safety. At PRO3S, we understand the importance of these additives and are committed to their responsible and effective use. Let's delve deeper into their role and benefits. What Are Feed Additives? According to the European Food Safety Authority (EFSA), feed additives are substances used in the manufacture of animal food to achieve specific objectives, including improving feed quality, optimizing animal health, and thereby ensuring the quality of food products derived from these animals. These additives are crucial for public health as they ...

Micronization in Various Sectors: A Key Process for Material Optimization Micronization is a crucial procedure in several industrial sectors, such as cosmetics, mining, pharmaceutical and veterinary industries, and third-party food packaging. This process involves reducing the particle size of various raw materials to micrometric dimensions, thus optimizing their handling and applications. What Is Micronization and How Is It Applied in Industry? Micronization is a physical process that reduces the particles of a material to sizes no greater than 10 microns. To give you an idea: 10 microns equal 0.01 millimeters. Thanks to the impact these particles undergo when circulating at high speed, they collide with other particles within a chamber, generating a powder of micrometric ...
