Our Story
Founded in 2022 by Sal Rigoroso (Formally Charleston Plastics), Cornerstone Plastic Recycling was born from a vision: that plastic waste shouldn’t be the end of the line — it should be the start of new value. With backgrounds in materials engineering and sustainability, our leadership assembled a team dedicated to financial, environmental and operational efficiency in recycling. Starting with post-industrial plastics, we’ve grown into a full-service recycling provider with scaling infrastructure, quality control, and trusted downstream markets.

What We Do
Plastic Collection & Sorting — we accept and manage plastic waste streams (e.g., bottles, film, rigid, flex) and sort by polymer, resin type and color to maximise value.
Recycling & Reprocessing — using industry-leading equipment and protocols, we process plastics into clean flakes, pellets or other feedstock for reuse in manufacturing.
Closed-Loop & Circular Solutions — we partner with brands and OEMs to design and implement flexible systems where recycled plastic re-enters production, reducing reliance on virgin resin.
Consulting & Compliance Support — we help clients meet sustainability goals, recycled content targets, regulatory standards, and document chain-of-custody for plastics streams.
By providing the full continuum — from waste stream to recycled feedstock — we help our clients streamline their supply chain, reduce costs, minimise environmental impact and strengthen their brand’s sustainability story.
Our Core Values
Quality & Integrity – We maintain rigorous standards at every step: collection, sorting, processing, and delivery. We stand behind accuracy, consistency and traceability.
Environmental Responsibility – We believe in responsible recycling that honours the planet: reducing waste, diverting plastic from landfills and lowering carbon footprint.
Customer-Focused Innovation – We work closely with clients to solve their unique challenges: custom resin blends, color match, recycled content percentages, just-in-time supply.
Transparency & Partnership – We build strong relationships with suppliers, collectors and customers; we share data, communicate openly, and deliver on commitments.
