My local council, in its wisdom, has just started a new waste recycling scheme. Each house now has a brown wheelie bin (for garden waste), a green crate (for glass and metal), a white plastic bag (for paper) and the original black wheelie bin (for everything else). These are all collected at various times according to a schedule which is so complex as to be virtually impenetrable. And, as if this isn't enough, all the glass and metal waste (including tins, foil trays, kitchen foil, etc) is supposed to be washed before putting it out. When you factor in the energy required to heat the hot water to wash the stuff, it's easy to believe that the environmental effects of this initiative may well be negative. And our Council Tax is increasing this year by about 20% too! Or am I just getting cynical?
In practice it isn't a big problem, if you sort your rubbish. In deep water, cans and bottles can be safely thrown over the side, to take the next century or two to biodegrade, and perhaps supply homes to some small fish. Vegetable and animal matter go over to feed the fish, and you are left with mostly paper and plastics. These will compact easily, and stay in a bag on deck until you get somewhere, when they can either go into a bin, or be burnt safely on the beach, if there is no rubbish system.Some people take stones with them to sink this sort of rubbish in deep water, which is not such a 'non green' idea when you accept that many places in less developed countries [ especially islands ] have no facilities for their own rubbish, and just tip it in the sea. I have also had 'boat boys'come alongside in dinghies, offering to take the trash away, only to recognise it on the beach later, opened, searched for anything worth taking, and thrown away.
My local Council has us jumping through hoops & sorting our rubbish out for trick cycling. Now they have been cought dumping it all in Landfill cos its too dificult to recycle.
I seem to remember reading about international conventions on waste disposal at sea. These define how far from land you need to be to chuck which sort of rubbish. Can't remember the details though.
I'm not sure that I am too happy about throwing anything over the side, unless it is bio-degradable, even in deep water. Surely everything should be stored until it can be properly disposed of. Should yachtsmen not be very 'green' and guardians of the sea?
i chuck everything except paper and plastic over the side but only in deep water (the channel dosn't count as deep) make sure you clean any rubbish staying on board or it will stink and flys will start buzzing round.
I think I remember a story from one of the early 'Whitbreads'. The boats had to store their rubbish onboard until arriving at port, part of a sea clean up drive. At the 'Rio' stop, I believe it was, they unloaded their rubbish and watch it put into a lorry. The lorry drove down the dock and unloaded the rubbish into a barge which was then towed out to sea where it was dumped.
3 weeks on passage in the tropics is a long time to keep all rubbish.
when coastal cruising nothing goes over the side but on a long passage you have to be realistic. bottles and cans sink and become part of the ocean floor along with dust, dead fish and everything else that sinks.
food and sewage are biodegradable and will disappear provided you don't drop them close to windward of a shore; probably the longest lasting are fruit skins.
paper disintegrates with water and wave action as long as it isn't plasticised.
plastic is of course a total nono. the worst offenders are clear polythene bags which turtles mistake for jellyfish and the interlocking rings from a six-pack which get round necks of many animals at sea or ashore.
Surely paper is one thing that could go over the side. Does Ellen and all those other racers chuck everything in during a race? If so, one never sees that in the documentary. I wonder why...
