Compostable Packaging for School Canteens FAQ

What packaging must a school canteen tender specify?

A canteen tender should fix the SKU list, a per-SKU food-contact statement, the disposal route the school can actually operate, and the certification listing behind any compostable label. Schools that write only a material type into a tender receive offers that cannot be compared, because each bidder prices a different product scope and a different document set. Write the SKU list first; the rest of the tender follows from it.

Is compostable tableware more expensive for a school?

The unit price is usually higher than plastic, but the per-meal comparison changes once disposal is counted. A school that sends fiber ware to industrial composting avoids general waste tipping fees and, in some jurisdictions, weight-based disposal charges. Model cost per meal across a full school year including collection and hauling, not cost per piece, because five cost lines — unit price, freight, storage, collection labor, and hauling — move at different rates.

What certification does a school need for compostable claims?

A live certification listing for each finished SKU, naming the coating and ink, from a recognized body such as BPI against ASTM D6400 or TÜV Austria OK Compost for European sites. A generic supplier certificate does not satisfy a public procurement audit, which reads documents per item rather than per invoice. Require the listing as a tender attachment rather than as a marketing statement, and re-request it each year.

Why does the waste route decide whether the switch holds?

Because a fiber tray sent to general waste breaks the case the purchase was made on. Four dependencies have to line up: a compost bin beside every general bin, picture-based sorting signage at the tray drop, collection scheduled to match meal times, and a hauler contract that accepts the certified SKU. Bins placed only at the exit collect a mix of ware, and contamination is what makes a hauler reject a load.

How should a school compare bids on packaging?

Compare landed cost per meal across a school year, not unit price. Freight scales with delivery frequency, on-site storage consumes space, and hauling scales with contamination rate. A slightly higher unit price with consolidated deliveries and low contamination can beat a cheaper unit price that triggers weekly overflow hauling. Put the waste route into the costing model instead of treating it as a footnote.

Should a district run a pilot before a full contract?

Yes. Run one kitchen, one SKU list, one waste route, and a contamination count at the end of a single term. A pilot converts the tender into a measured decision: the heat-hold and leak results tell you whether the ware suits the menu, and the contamination rate tells you whether the hauler will accept the load. The pilot data then becomes the specification for the district-wide contract.

What belongs in a canteen packaging PO?

Six items: a SKU list with item, size, and count per case; a food-contact statement per finished SKU; a live certification listing naming coating and ink; a heat-hold and leak test at service temperature; a term delivery schedule with drop points; and confirmation that the waste hauler accepts the certified SKU.
