Grade A is food-grade eligible or rebottled: clear to near-clear bottle, documented edible prior service or a new bottle, new valve, gaskets and lid, re-marked. Grade B is washed industrial: sound bottle with haze or staining permitted, square cage, leak tested. Grade C is rinsed and as-is: watertight and structurally sound but cosmetically marked, for non-contact storage, water and projects. The definitions are contractual and printed in our terms.

The inbound inspector, in writing, before anyone in sales sees a price. Nobody in sales can overturn a grade. It is the most consequential job in the building and it is deliberately insulated from the commercial side.

Functionally, almost never. Staining and haze define the Grade A / Grade B boundary, which is a price difference rather than a performance one. It matters where clarity matters: light-coloured products, visual level checks and audit-exposed food work.

A permanent shadow in the bottle wall left by a prior pigment, resin or dye that has migrated into the polymer. It cannot be washed out. A ghosted bottle is Grade C at best, and often a rebottle candidate.

Not as a stacking base when filled. We will not sell one for that purpose. Empty and stacked for storage is fine; filled and used as the bottom of a two-high stack is not.

Only downward, and only on re-inspection after a failed wash. Re-grading upward to clear a backlog or fill an order is how reputations end, and it is the fastest way to lose a job here.

About 2,590 lb for a 275-gallon unit filled with water, and about 3,100 lb for a 330. For other liquids multiply the liquid weight by specific gravity: a 275 of 50% caustic is around 3,500 lb, which exceeds a great many rack beams and lift gates.

Composite IBCs are typically rated for it, with a square cage, sound welds, an undamaged pallet and Grade A or B condition. Heavier unit on the bottom, never on soft or uneven ground, and check your ceiling and sprinkler clearance before you plan around it.

Vented for anything pumped, fermenting or off-gassing, and for outdoor storage where day–night temperature swings breathe the container. Solid for sealed transport. A transfer pump on a sealed container collapses a wall panel.

EPDM for water-based chemistry, dilute acids and alkalis, glycols and most food products. Viton for aromatics, chlorinated solvents, fuels, oils, fats and higher temperatures. Silicone for high-temperature food transfer. PTFE when nothing else is chemically acceptable.

Three times out of four it is the outlet gasket, not the valve or the container. Over three years of complaints: 71% gasket, 14% valve seat, 9% lid seal, 6% actual bottle failure. Replace the gasket and the lid seal before you replace anything else.

Up to about 120–140°F with care. Above that HDPE softens, the bottle deforms under head pressure and then draws inward as it cools. If your process needs genuine hot fill, use stainless.

Do not leave it full and sealed. Water expands about 9% on freezing. Drain it, or leave it no more than two thirds full with a vented lid, and insulate or remove the valve and plumbing — fittings freeze long before the bulk does. Heater jackets and insulated covers are available.

Roughly five years of unshaded outdoor UV exposure, or ten to fifteen years indoors or covered. The cage will outlast three or four bottles. UV is the limiting factor, not water, age or chemistry — cover it and you double or triple its life.

Not by the cage top unless the unit is specifically designed and marked for it, and never when filled. Composite IBCs are designed for forklift and pallet-jack handling from the base. Lifting a filled unit by its frame is how cages come apart.

Very little. A composite IBC is designed for the static head of its contents, not for internal pressure. We leak test at 3 psi; a few psi is enough to deform a bottle noticeably. Never pressurise one to assist discharge unless it is a vessel rated and marked for it.

Yes — contract reconditioning. We collect, run them on the programme their residue requires, leak test, re-valve and re-gasket to your specification, and redeliver. They stay your property, and you get the wash record, test record and photographs per serial.

Yes, per unit per week with a typical four-week minimum, plus freight both ways. It is the right answer for seasonal, campaign and project demand — and the highest-utilisation form of reuse there is.

Yes, and it is usually cheaper than contract washing. We deliver washed, graded, tested units and take your dirty ones away on the same truck, so freight is paid once instead of twice and nobody waits for a wash cycle.

Average gate-to-graded turnaround is 72 hours. A 40-unit batch typically moves through in a single day of bay time once scheduled; the constraint is almost always lane availability rather than the wash.

No. The water loop, the dissolved-air flotation, the manifested sludge route and the recorded parameters all live at our yard. Mobile washing produces a wet container and a drain problem, not a document an auditor will accept.

Yes, for every end-of-life batch on request: unit count, weight by material stream, destination route and date. It is designed to drop straight into corporate waste or ESG reporting.

Not by the cage top unless the unit is specifically designed and marked for it, and never when filled. Composite IBCs are designed for forklift and pallet-jack handling from the base. Lifting a filled unit by its frame is how cages come apart, and the failure is sudden.

Very little. A composite IBC is designed for the static head of its contents, not internal pressure. We leak test at 3 psi; a few psi is enough to deform a bottle visibly. Never pressurise one to assist discharge unless it is a vessel rated and marked for it.

The outlet sits slightly above the floor of the bottle, so a gallon or two of heel always remains. A tote tipper frame or a stand that lets you tilt the unit recovers most of it. Do not tip a tote on a forklift without a proper attachment.

Yes, with two precautions that double or triple the bottle's life: block the light, and never leave one full and sealed through a freeze. Unshaded full sun takes a bottle from ten-to-fifteen years down to three-to-five.

That depends on your product and your jurisdiction rather than on the container. Spill pallets and bunds for one, two and four totes are available and are routine for anything regulated or anything that would be expensive on a floor.

A 48 × 40 footprint needs about 42 inches of clear door with a pallet jack leading on the 40-inch side, and roughly 48 inches of swing to turn a corner. Measure the narrowest point of the whole route, not just the doorway.

Empty and indoors, three is common and four is possible with square cages on a level floor. It is a stability question rather than a strength one — an empty stack is light, tall and easy to catch with a forklift mast.

Yes, and by about an order of magnitude. A new 275-gallon composite carries roughly 410 lb CO₂e; reconditioning an existing one costs about 34 lb. Almost all of a container's footprint is spent forming its shape, and reuse keeps the shape.

97.4% of inbound weight for 2025, measured on certified scales at the gate and at every outbound route and reconciled monthly. The remaining 2.6% is manifested residue sludge, which cannot be diverted.

Because every wash line produces sludge, and there is no chemistry in which removing residue from containers makes the residue cease to exist. A yard claiming full diversion is either not counting that stream or not mentioning it.

No, and we have no tonnage targets that would reward it. A bottle reaches the granulator only after failing reuse twice — once at inbound grading and once after a wash attempt. Cages and pallets are always assessed independently of the bottle.

Replace seals rather than containers, and cover the units. The valve and seal set is about a quarter of a reconditioned unit's remaining footprint, and blocking light doubles or triples bottle life.

We issue diversion certificates per batch with unit counts, weights by material stream, destination routes and dates. That batch-specific document is the right basis for your reporting; our yard-wide percentage is ours, not yours.
