How do I count latex and backing cloth in a tufted carpet footprint?
Latex compound and backing cloth are purchased materials, so they go in Scope 3 Category 1 for your company and in the cradle to gate figure per square metre. Multiply kg used per square metre by a supplier or published factor for each material, and add the energy of the curing oven.
Materials
- Latex: synthetic SBR or natural rubber, with different factors.
- Primary and secondary backing: cotton, jute or polypropylene.
- Filler such as chalk in the compound.
Curing
Gas, diesel or wood burned in the drying and curing stage, per square metre, from fuel invoices and production logs.
Where to find factors
Ask the latex and cloth suppliers first; use a published average only when they cannot answer, and label it.
What Senseible does here
Senseible reads purchase invoices into a dated, fingerprinted record, so each supplier figure in your Scope 3 sits next to the quantity and the document it applies to.
