"Findings I" - These suggest that household cooking oil users are short of suitable options provided by waste-collectors

"Findings II" - These suggest that household cooking oil users are short of suitable options provided by waste-collectors. Identified in the studied sample of participants when disposing of their used cooking oil - Most Recurrent Behaviours emerged as:

• Down into the drains - SINK and TOILET.

• Bottled it to Recycle or Wipe-it & Bin-It.

Although, MOTIVATION was found in form of an available willingness to change behaviours, particularly those implicit on Fatbergs outbreaks (Sink/Toilet) if the OPPORTUNITY arises in form of interventions made available to households, comprising user-centred schemes for oil disposal mitigated by either waste collectors in town, the local council or water utility.

"Findings III" - The findings suggested that household cooking oil users feel let down by the lack of suitable oil disposal options. Meanwhile, with exceptions, Out-of-sight then Out-of-mind feelings prevail.

The findings outlined from coded the transcripts using the COM-B model (Michie, Atkins et al.,2014; Michie, van Stralen et al.,2011) and the TDF (Cane et al.,2012) have constructed the themes identified. Then, the emerging results generated with the application of the COM-B and TDF framework suggested that, in general, cooking oil users from households from this Charnwood area. Yet, it may include the remaining widespread to all over the UK, are still short of appropriate options provided by waste-collectors and to deal with this form of waste. 13 TDF elements were identified emerging from initial COM-B components, with a few exceptions, the feeling of out-of-sight-out-of-mind prevails and waiting for appropriate interventions that could retrieve used cooking oils out of users hands and prevent the Fatberg outbreaks.

"Findings IV" - Relationships - In which category household's sampled participants were found?

"Findings" - Relationships - In which category household's sampled participants cooking oil users neutralize?

A collage of a few stills pictures retrieved from video demonstrations of participants disposing of their cooking oils after finishing cooking. Genuinely, those framed here, categorised as Fatberg friends, did not reveal any malice intentional in disposing of the oil down the drain this way, for contempt or negligence. But this could be identified as an easy and gullible way to do it, regardless of other additional considerations of doing it using plenty washing up liquid and hot water will be sufficient to neutralise the congealing propriety of oils and fat after disposed of this way.

"Findings V" - Results revealed by the sample of participants

The word cloud answers with the findings illustrating participants reasonings. The first set reports how and what they do. However, the second set of questions reveal an existing MOTIVATION willingness to change behaviours, depicted as “YES” if the OPPORTUNITY of a well-implemented intervention rises, combining household users considerations and needs in mind, as reported by households sample in this study.

The NVivo consolidated table assorts the whole questionnaire answers of the interview schedule and for a seemly visually presentation. This outline encompasses the qualitative data analysis provided by the behaviour change frameworks used, .i.e. BCW with COM-B and TDF.

"Conclusion/ Discussion" - Results suggested that household cooking oil users are still short of suitable options provided by waste-collectors.

The outcome of discussing findings and results emerged by the application of the COM-B and TDF framework suggested that, in general, cooking oil users from households, in this case, from this Charnwood area, although also widespread to all over the UK, are yet short of suitable options provided by waste-collectors to deal with this form of waste.

Scattered enablement of pilot trials emerging, e.g., Sainsbury's/Olleaco/Scottish Water at an Edinburgh's, a supermarket car park cooking oil collection, are not part of an effective national campaign to stop Used Cooking Oil (UCO) disposals down into the drains. Therefore, it will be challenging to see replications or even find established reasoning out of such subjective small-scale regional experiment.

Legal cause through coercion is almost unfeasible, due to the household's privacy issues. Other leading research Team of Social and Human Scientists experts mainly based in Manchester/Sheffield/Keele funded by the ESRC, stressed the same concerns at the "NEXUS at Home" WEF Project. There is need for more research addressing this problem by applying practice theory to inform better interventions aimed at changing behaviours regarding this context of the "Water, Energy and Food" (WEF) NEXUS in the home.
