A brand-new study determines strategies that could decrease the use non reusable coffee mugs.
Scientists at Cardiff College evaluated a variety of measures to motivate the use recyclable coffee mugs in behalf of the foodservice coffee company Bewley's. They found that monetary rewards, re-usable options, and clear messages advising customers of the ecological impact of single-use coffee mugs all had a straight effect on customer habits.

The study discovers that:
a fee on non reusable mugs enhanced the use recyclable coffee mugs by 3.4 percent;
ecological messages in coffee shops enhanced the use recyclable coffee mugs by 2.3 percent;
the accessibility of recyclable mugs led to an increase of 2.5 percent;
and the circulation of free recyclable mugs led to an additional increase of 4.3 percent.
"While the increases for individual measures were moderate, the best behavioural change was when the measures were combined," says study writer Wouter Poortinga, a teacher at the Welsh Institution of Architecture.
The study found that the arrangement of free re-usable options combined with clear ecological messaging and a fee on non reusable mugs enhanced the use recyclable mugs from 5.1 percent to 17.4 percent.
"Our outcomes show that, typically, the use recyclable coffee mugs could be enhanced by up to 12.5 percent with a mix of measures. With this in mind, the UK's use of an approximated 2.5 billion non reusable coffee mugs each year could be cut by up to 300 million coffee mugs," Poortinga proceeds.
One of the most noteworthy finding was that although changing for non reusable mugs enhanced the use recyclable coffee mugs, a discount rate on recyclable coffee mugs had no effect on their use.
"There's an important nuance when it comes to monetary incentives…" says Poortinga. "Individuals are much more conscious losses compared to to acquires when production decisions—so if we really want to change a customer's habits after that a fee on a non reusable mug is more most likely to work."
