SIR srl

What SIR srl does

SIR srl (also marketed as SIR Green Compounding) is an Italian B2B manufacturer of custom-formulated recycled plastic compounds, founded in 1998 and headquartered in Piazzola sul Brenta, Italy. The company produces tailor-made recycled polymer compounds for industrial customers across multiple end-markets, including storage, automotive, office furniture, garden furniture, and industrial components. Operations are anchored at a 70,000 m² facility running seven compounding lines with a combined capacity of approximately 50,000 tons per year, supported by 41 employees and two 24/7 quality control laboratories.

The company's product portfolio is organized under branded polymer families: SIRPLENE (polypropylene), SIRTENE (HDPE/LDPE), SIRSTIR (polystyrene), and SIRLAC (ABS). In 2024, SIR launched the VERIS brand through a partnership with the VERITAS Group, extending into post-consumer recycled compounds. The company holds ISO 9000, ISO 14000, Plastica Seconda Vita, and RecyClass certifications, and operates a trigeneration plant (installed 2019, 80% efficiency) supplemented by solar panels installed in 2025 to manage energy cost and carbon footprint.

SIR's business model is contract manufacturing of recycled plastic compounds sold to industrial buyers, with revenue generated per ton of formulated product sold. The legal form is an S.r.l. con socio unico (single-member limited liability company) with a reported share capital of €1,088,889 in 2025. While the product and end-market mix is diversified, no individual customer logos or revenue split by segment is disclosed in the available data.

Revenue model

1. Recycled Plastic Compound Sales: SIR generates revenue through the manufacture and sale of customized recycled plastic compounds (polypropylene, polyethylene, polystyrene, ABS) to B2B customers across storage, automotive, office furniture, garden furniture, and industrial sectors. Compounds are sold as plastic granules in natural, black, or custom-colored versions. The revenue model is transactional, based on volume (tons) of compound sold, with pricing that varies by polymer type, formulation complexity, and color specifications.

Core offering

SIR manufactures and sells custom recycled plastic compounds produced from post-industrial and post-consumer polymers. The product range covers regenerated polypropylene (SIRPLENE), polyethylene HDPE and LDPE (SIRTENE), polystyrene (SIRSTIR), and ABS (SIRLAC), supplied in natural, black, or custom-colored granule form to industrial manufacturers. Compounds are formulated to customer-specified mechanical, aesthetic, and processing requirements, with a minimum sample quantity of 25 kg.

Product overview

SIR srl is a plastic compounding company specializing in high-quality recycled plastic compounds. The company operates four core product lines: SIRPLENE (polypropylene), SIRTENE (polyethylene HDPE/LDPE), SIRSTIR (polystyrene), and SIRLAC (ABS). All products are produced from post-industrial and post-consumer recycled plastics. The VERIS sub-brand, launched in 2024 through partnership with VERITAS Group, focuses specifically on post-consumer waste transformation into certified recycled compounds. The company offers highly customized formulations tailored to specific client requirements across automotive, furniture, storage, and industrial sectors.

Brands

• VERIS: Brand created in 2024 through partnership between VERITAS Group and SIR for circular economy in plastic recycling. VERIS transforms post-consumer plastic waste into regenerated and certified compounds (secondary raw materials). The name combines 'VE' from Veritas and 'RIS' (reverse anagram of SIR), also referencing Latin 'Veris' (spring) symbolizing rebirth.

Products and services

• SIRPLENE Regenerated polypropylene compound available in homopolymer (PPH) and copolymer (PPC) variants, supplied in natural, black, or custom-colored versions. Highly versatile and applied across automotive, office furniture, storage, garden furniture, batteries, and industrial and civil containers.
• SIRTENE Regenerated polyethylene compound line including HDPE for applications requiring strength and durability, and LDPE with excellent water resistance for packaging applications. Available in natural, black, or custom-colored versions.
• SIRSTIR Regenerated polystyrene compound line including crystal and high-impact variants, valued for lightness and versatility. Applied in appliances, packaging, and products such as hangers and spools. Available in natural, black, or colored versions.
• SIRLAC Regenerated ABS (acrylonitrile butadiene styrene) compound, widely used for structural components in construction and appliances due to its strength, resistance, and durability. Available in black or custom-colored versions.
• VERIS recycled plastic compounds VERIS branded compounds produced from post-consumer plastic waste through the VERITAS-SIR partnership supply chain. Includes sorting lines for PP and PE separation and production lines for rigid and film plastics, producing end-of-waste material in flakes or agglomerate form for sale to industrial buyers.

Partnerships

One partnership is on record.

• VERITAS GroupcoreStrategic or Co-development Partner · 1 January 2024Partnership established in 2024 between VERITAS Group (Venetian public utility managing waste collection and recycling) and SIR for the VERIS brand. VERITAS provides exclusive access to post-consumer plastic waste through their full waste cycle management, prioritizing recycling and material recovery. The collaboration enables a certified supply chain transforming post-consumer waste into high-quality recycled plastic compounds, with SIR controlling and certifying the process from post-consumer stage through finished compound. VERITAS handles collection, optical sorting, material separation, washing, and grinding of household plastic waste before SIR processes it into compounds.

Direct peers

• MBA Polymers: Global recycler of post-consumer plastics (PP, ABS, PS, PC) producing high-quality PCR compounds for automotive, electronics, and consumer goods. Directly comparable to SIR's multi-polymer, custom-formulation approach.
• KW Plastics: One of the largest North American post-consumer and post-industrial recyclers of HDPE and PP, producing custom recycled compounds for similar end-uses (containers, automotive, industrial). Closely comparable to SIR in business model — PCR/PIR compounding with traceability and customization at scale.
• Envision Plastics / Envision Plastics Recycling: US-based recycled HDPE and PP compounder producing FDA-grade and custom PCR compounds for packaging, automotive, and consumer products. Comparable to SIR in PCR/PIR compounding and end-market focus.

Emerging players

• PureCycle Technologies: US-listed recycler using a chemical (solvent) recycling process to purify post-consumer PP into virgin-grade resin. Adjacent to SIR's mechanical-recycling PP compounding business; relevant as a competitive/technology reference for the recycled-PP market.

Broad incumbents

• Suez (Recycling & Recovery): European environmental services incumbent with plastics sorting and recycled polymer production. Comparable to Veolia as a broad recycling player that overlaps with SIR's upstream feedstock and downstream compounded-product markets.
• Birla Carbon / Aditya Birla (Recycled Materials): Global carbon black and recycled-polymer producer with European compounding operations. Broad incumbent competing for recycled-compound share across automotive and industrial applications.
• LyondellBasell (Circulen, PreZero): Global polyolefins leader with a Circulen recycled-content portfolio and PreZero recycling operations in Europe. Produces virgin and recycled PP/PE compounds at much larger scale — competes for the same OEM customers and shapes market pricing.
• TotalEnergies (Recycling / Polymers Europe): Integrated energy and petrochemicals major with European polyolefins and recycled polymer operations. Operates at larger scale and broader portfolio, but overlaps in PP/PE recycled compound supply for European industrial customers.
• Borealis (Borcycle, OMV): Austrian polyolefins and recycling major with Borcycle mechanical-recycling compounds in PP and PE. European peer with overlapping end-markets (automotive, packaging, consumer durables) and a broader virgin-resin portfolio.
• Veolia (Recycling & Plastics): Global environmental services giant with plastics recycling and compounding operations across Europe. Broader and larger portfolio than SIR but overlaps in PCR polymer recovery and supply — relevant for sourcing dynamics and competitive context.
