Reusable packaging

Reusable pack­ag­ing is man­u­fac­tured of durable mate­r­ials and is specif­i­cally designed for mul­ti­ple trips and extended life. A reusable package or container is “designed for reuse without impairment of its protective function.” [1] The term returnable is sometimes used interchangeably but it can also include returning packages or components for other than reuse: recycling, disposal, incineration, etc.[2]

Reusability of packaging is an important consideration of the environmental credo of “reduce, reuse, and recycle”. It is also important to the movement toward more sustainable packaging. Returnable packaging is encouraged by regulators.[3][4]

Industrial shipping containers[edit]

For many years, several types of shipping containers have been returnable and reusable. These have made most sense when a reverse logistics system is available or can be readily developed.[5]

Manufacturing, particularly the automobile industry, has used heavy-duty returnable racks for shipping hoods, fenders, engines, dashboards, etc from suppliers to final assembly plants. The racks are then returned for the next shipment cycle.

Bulk foods, chemicals, and pharmaceuticals are often shipped in reusable and returnable containers. These need to be carefully inspected, cleaned and sanitized as part of the reuse cycle. An effective Quality Management System is necessary.

Wooden pallets are often made to be expendable, for a single shipment. Others are heavy duty and intended for multiple shipments. Some are in “pallet pools” which are used, inspected, and refurbished for extended usage.

Often reusable industrial shipping containers have bar code labels or RFID chips to help identify and route the containers.

Consumer packaging[edit]

Several types of consumer containers have been in reuse systems. Reusable bottles for milk, soda, and beer have been part of closed-loop use-return-clean-refill-reuse cycles.

Home canning often uses glass mason jars which are often reused several times.

With any food packaging, proper cleaning and disinfecting between each use is critical to health.

Reuse for other purposes[edit]

Used packages are often reused for purposes other than their primary use. For example, a single-use plastic shopping bag might be reused as a trash bin bag, a household storage bag, or a dog feces bag.

Justification[edit]

Reusable packaging often costs more initially and uses more and different materials than single-use packaging. It often requires adding complexity to the distribution system. Not all packaging justifies being returnable and reusable.

A thorough cost analysis is required. This involves all of the material, labor, transport, inspection, refurbishing, cleaning, and management costs. Often these costs may be incurred by different companies with different cost structures.[6][7]

The environmental costs and benefits can also be complex. The material, energy, pollution, etc needs to be accounted for throughout the entire system. A Life Cycle Assessment offers a good methodology for this task.[8][9][10][11]
