Council tips will accept cooking oil as well as engine oil. 2 litre plastic cola/water bottles are ideal for storage, when the oil has cooled of course.
Oil should never be poured down the sink as it emulsifies into sticky lumps and causes blockages in the sewerage system. A time consuming, expensive and growing problem for the water companies to deal with.
Wit’s ideas are spot on.
DIY fatballs for our avian friends are much cheaper than shop bought. The peacocks (aka house sparrows) in my garden love them, as does Ratty.
Incidentally if you can manage to do without the delicate fragrance of a virgin wafting around your olfactories, then used olive oil is quite adequate for a ‘greasy spoon’ fry-up once it has been stored awhile in the aforementioned bottles allowing time for solids to sink to the bottom.
