Your bottle's footprint comes from the furnace and from the container it crosses the ocean in, and both sit inside the two sites MAIDAO runs in Shandong and Xuzhou. Natural gas since 2016, 20–30% recycled cullet in the batch, and NNPB forming that takes weight out of a wall your drinker never notices.
Guides on cullet, carbon and EPR fees →Three separate sources, and your leverage over each one is different.
The fuel that holds a furnace at melting heat is the largest single share, and it belongs to your factory rather than to your buying decisions. SGSBOTTLE, a glass bottle manufacturer with 14 lines in Shandong and Xuzhou, came off coal onto natural gas in 2016, so every bottle formed since carries that profile.
Soda ash and limestone give up CO2 as they decompose, and that happens whatever fuel a plant burns. Cullet is your lever against it: melted glass has already given up its carbon, so every tonne of cullet in the batch displaces raw carbonates and the emissions they would have released.
Glass is dense, so the lane out of China puts real weight into your total. A lighter 750 ml (25 oz) bottle carries less glass through the furnace and less mass across the ocean, and the two savings add rather than cancel.
Gram count follows your order into every bill after the furnace: sea freight, the EPR fee your importer pays per tonne of glass placed on the market, and the pallet positions your warehouse rents.
All four run today across the two sites, and each of them reaches your invoice somewhere.
The conversion off coal cut CO2, SO2 and NOx at the furnace, where a bottle's largest emission share comes from.
Clean, colour-sorted cullet melts under the heat raw batch needs, so it cuts fuel and carbonate chemistry at once.
Narrow-neck press and blow spreads glass evenly enough to take weight out of the wall, in Shandong.
Glass goes back to the furnace with no loss of purity, so your cullet this year becomes your bottle next year.
Colour and glass type decide the site, and the site decides how much cullet your batch can carry.
| Site | Glass | Lines | Inspection | What it runs |
|---|---|---|---|---|
| Shandong, Shandong | flint and super flint | 7 | Machine + manual | volume flint and super flint |
| Xuzhou, Jiangsu | flint | 7 | 100% manual | our own plant, mixed runs |
Cullet share moves with colour and with what the collection stream around a site delivers, so the figure for your order comes back with your quotation instead of as a site-wide average. Flint carries less than amber and green, because contamination shows in clear glass.
Your load plan and your EPR return read from the same gram count.
| Format | Units per 40HC | What moves the number |
|---|---|---|
| 750 ml (25 oz) round | 25,000 | Pallet pattern and carton size. |
| 750 ml (25 oz) irregular | 22,000 | An oval or square footprint loses cases. |
| 12 oz (355 ml) beverage | 60,000 | Bottle height and the crate you fill. |
Taking weight out of a wall starts as a mould decision. It changes the drawing, your filling line has to accept the new bottle, and the saving only counts once your line runs it at speed.
Your EPR fee follows that gram count every year the SKU sells, so a lighter bottle keeps paying you back long after the tooling has stopped costing anything.
Four things your quotation and document pack carry, and one thing they do not.
A third-party verified life-cycle assessment and a certified environmental management system are different documents from anything in that pack. Your enquiry gets a straight answer on what exists before any number reaches your customer's file.
The library entries these figures rest on, written for the people who buy packaging.
Cullet is crushed recycled glass fed back into the furnace. What it does to energy, quality and your recycled-content claim, and why colour separation limits it.
Read the guide →Melting, chemistry and freight each contribute. Where the carbon in a glass bottle actually comes from, what cullet and fuel change, and which lever is yours.
Read the guide →A recycled content figure on your pack is a public claim. What pre and post-consumer mean, how mass balance works, and what evidence a regulator expects.
Read the guide →Collected glass and furnace-ready cullet are not the same thing. What happens between the bin and the batch, and why colour sorting decides the outcome.
Read the guide →Two life cycle assessments of the same bottle can disagree completely. What scope, functional unit, trips, allocation and sponsorship each do to a result you are shown.
Read the guide →Extended producer responsibility charges you by weight, every year you sell. Who the obligated party is, how fees are modulated, and what your reporting rests on.

Cullet runs 20–30% of the batch across our melts. The share for your order depends on colour and on the site that runs it: flint carries less than amber or green, because contamination shows in clear glass, and your quotation states the position for your colour.
Yes, without limit. Glass returns to the furnace with no loss of purity or performance, and cullet melts under the heat raw batch needs, so a returned bottle saves fuel as well as raw material.
Natural gas, since 2016. The conversion off coal cut CO2, SO2 and NOx across the two sites in Shandong and Xuzhou, and it covers all 14 lines.
Not as a third-party verified number. What comes back with your quotation is the input your own assessment needs: bottle weight from the drawing, the cullet position for your colour, the fuel at the furnace and the units per 40HC on your lane.
Yes, where your market charges by weight, and most markets do. The fee lands every year the SKU sells, so grams taken out at the mould stage keep returning long after you have paid for the tooling.
Cullet means crushed glass going back into the furnace with the raw batch, and clean cullet costs your bottle nothing in strength. Glass loses no quality on remelting; what does cause defects is contamination, when ceramics, stones or metal ride the cullet stream into your glass.
Your current bottle, your annual volume and your markets are enough to start. What comes back:
