Beverage Depackaging: Separating Liquids, Aluminum, Glass and PET

Every beverage company eventually ends up with product it can’t sell. A batch misses spec, a label carries the wrong lot code, a seasonal flavor goes out of code, or a recall pulls pallets back from the market. The product has to be destroyed so it can never be resold, but landfilling full cans and bottles wastes recyclable material and many landfills restrict liquid waste.

Depackaging is the answer. It’s the process of opening sealed containers, separating the liquid from the packaging, and sending each stream — liquid, aluminum, glass, PET plastic, cardboard, and film — to the right recycling or recovery outlet.

Common reasons product ends up in a depackaging program:

• Expired or out-of-code product
• Recalls and market withdrawals
• Off-spec production runs and mislabeled product
• Damaged pallets and warehouse breakage
• Discontinued SKUs, seasonal leftovers, and overstock

The same process covers bottled water, soft drinks, energy and sports drinks, juice, ready-to-drink coffee and tea, beer, wine, and spirits.

How Depackaging Works

Equipment varies from site to site, but most programs follow the same five steps.

1. Receiving and documentation. Pallets arrive under a bill of lading. The processor records SKUs, case counts, and weights, and keeps product secure until it’s destroyed. For recalls or branded product, chain of custody starts here.
2. Breaking down secondary packaging. Shrink wrap, stretch film, corrugated trays and cases, paperboard carriers, and pallets are removed and sorted for recycling.
3. Opening the containers. Cans and bottles are punctured, crushed, shredded, or pressed. Common equipment includes liquid-extraction balers that drain and bale cans or PET in one step, perforators, and dual-shaft shredders that separate liquid from glass, aluminum, and plastic.
4. Capturing the liquid. Drained product is screened and collected in tanks or totes so it can be sent to an approved outlet instead of a storm drain.
5. Separating and preparing materials. Aluminum is baled or densified, PET is baled, glass is collected as cullet, and corrugated and film are baled. Each stream is then shipped to a recycler or end user, and the customer receives a certificate of destruction.

The key point for brand owners is step 3. Once a container is punctured or crushed, it can’t be resold, which is what makes depackaging a secure form of product destruction rather than just disposal.

Where Each Stream Goes

Liquids. This is usually the largest stream by weight and the hardest to manage. Sugary drinks, juices, and beer are high in organic content, which is why many sewer authorities restrict or charge for direct discharge. Better outlets include:

• Anaerobic digestion. Digesters convert sugars and alcohol into biogas. Equipment makers note that drained beverage liquid can be filtered and sold to biogas plants.
• Ethanol recovery. Beer, wine, and spirits can go to facilities that recover the alcohol for industrial use.
• Permitted wastewater treatment. Lower-strength liquids such as water and some flavored waters may be discharged under a permit, sometimes after pretreatment.

Aluminum. Drained cans are crushed and baled or densified. Because aluminum used beverage cans (UBC) are one of the most valuable recycled commodities, this stream often offsets a large share of the cost of a destruction program.

Glass. Bottles are broken into cullet and, ideally, kept separated by color (flint, amber, and green) for container glass manufacturers. Mixed or contaminated cullet has lower value and fewer outlets.

PET. Bottles are drained, baled, and sold to reclaimers who wash and flake them for new bottles, fiber, or strapping. Caps and labels are usually tolerated in bales, but heavy residue can lower the price.

Secondary packaging. Corrugated cases and trays become OCC bales. Shrink wrap and stretch film become PE film bales. Pallets are reused or recycled.

Other formats. Aseptic cartons, pouches, kegs, and bag-in-box packaging can also be depackaged, but their materials have fewer recycling outlets, so confirm a plan before shipping them.

Compliance Considerations

Certificate of destruction. For recalls, brand protection, and accounting write-offs, you need proof the product was destroyed. A good certificate lists SKUs, quantities, weights, the date and method of destruction, and where each material stream went. Some brands also require photos, video, or a witnessed destruction.

Alcohol and federal excise tax. Brewers can recover federal excise tax on beer destroyed off brewery premises. Under TTB rules, the brewer files a notice of intent at least 12 days before destruction, and TTB may choose to witness it. The brewer then files a refund claim on TTB Form 5620.8 with proof of destruction. Wine and spirits have their own rules, so involve your compliance team before the product ships.

Wastewater. If liquid goes to a sewer, the destruction facility needs the right discharge permit. High-sugar and high-alcohol liquids can exceed local limits on biochemical oxygen demand, which is why digestion or ethanol recovery is often the better outlet.

California Redemption Value (CRV). In California, CRV refunds are only for eligible empty containers redeemed through the state program. State law treats claiming CRV on ineligible material — including out-of-state containers, rejected containers, or line breakage — as fraud. If you’re a California distributor or bottler, ask your depackaging partner how it handles containers from destroyed product, and confirm that it’s certified and familiar with CalRecycle’s program rules.

Choosing a Depackaging Partner

Before you ship a single pallet, ask these questions:

1. Where does the liquid go? Get the name of the outlet, such as a digester, ethanol plant, or permitted treatment facility. “Down the drain” isn’t an answer.
2. What percentage of the packaging gets recycled? Ask for diversion reports by material.
3. How is security handled? Look for chain-of-custody paperwork, secured storage, camera coverage, and the option to witness destruction.
4. What’s on the certificate of destruction? It should support recall closeout, insurance or tax claims, and audits.
5. Can they handle all your formats? Cans, glass, PET, cartons, kegs, and mixed pallets in one program simplify logistics.
6. How is the material credited? Ask whether aluminum and PET value is reflected in your pricing.
7. Is the facility certified? Secure-destruction credentials, such as NAID AAA certification, and current environmental permits show the operation is audited.
