*** Update March 2024
Finally Available in a Refill pack that weighs 133g holding 125g of coffee -
is still more than the jar packaged version at £3.34 / 100 g (with Nectar ) or £4.60 /100g without card.
On the plus size looks like they have ditched the stupid big plastic top.
========= Previously
I like a cup of strong flavour instant coffee, I also like to recycle and encourage reduction in packaging.
In a fit of packaging madness Jacobs Douwe Egberts lo'r has this most ridiculous plastic top on it's instant coffee.
551g Total Jar made up of
347g of glass -> 62.3 %
37g of plastic top -> 6.7 %
167g of product -> 30.3 %
Looking by height
19cm Total Jar
16cm Glass -> 84 %
6.5 cm plastic top -> 15% which overlaps jar by 3cm and has a further 3cm on top of that.
This type of plastic top is typically non-recyclable ( unlike the glass ) and has no recycling marks identifying the plastic. There is also a plastic film wrapping the glass, which may look nice but does nothing for the recycling process.
Is there a more effective packaging solution ? Yes but the economics don't look great on the latest Morrisons shopping trip.
L'or = £2.34 per 100g
Nescafe gold refill pack = £3.00 per 100g ( no glass, minimal plastic bag )
66p more expensive for packaging free refill option. Sigh.
Even worse for the environmentally minded Morrisons on-line shopping currently has the refill pack 50p / 100g more expensive than the glass jar version. 6 Nov 2017.

Madness.

Thank you for contacting L’Or.
The lid is made of plastic and is recycled through
standard plastic recycling bins.
Kind Regards
