Net: 1 bin of 20 L per week for 5 people when we are crossing.
Compared to the class that is 3 times less, compared to a family 4 people it is 8.5 times less.
WHAT IS?
Before You Go: We watch what we buy: we prefer large containers: packages of 10kg of rice rather than 1kg. We also avoid over packaged products with few consumables. We do not consume products that generate fees in general waste a lot of yogurt, cheese, sour cream ... For water we use cans of 20L that we meet in the ports.
During the passage: A portion of our waste can be discharged into the sea without polluting. We must consider the sea off as a dustbin for biodegradable waste, organics, metal, paper and glass. Everything else, plastic, batteries, bottles of milk ... are thrown into the dustbin of the boat.
We throw the glass and metal that when we're far from shore (12 miles * = 21km) waste flow and are not rejected on the coasts, they are not a danger to the marine environment (Fauna and drill), they degrade even faster in water than on land.
* The International Convention for the Prevention of Marine Pollution (MARPOL) prohibits any vessel to throw plastic anywhere at sea food, cardboard, metal (cans) and glass are disposable at over 12 miles of coastline. Source: "Questions of marine curious"
That's life on the boat that we "force" to be like that, it teaches us to quel point il est facile de réduire nos déchets mais nous sommes conscients qu’il est difficile de se priver de certaines choses si faciles d’accès en France. Une fois revenu sur terre je pense que nous réduiront, naturellement nos déchets, mais nous ne pourrons pas revenir au niveau atteint sur le voilier.
Votre œuvre collective représente exactement le genre de déchets que nous n’utilisons pas. Gobelets plastiques (nous en avons sur le bateau mais nous réutilisons), yaourts…
Petite anecdote : what country we visited that pollutes the least? That spends the least? Who in the water / beaches cleanest ? Answer: Cuba.
Indeed Cuban life, completely away from mass consumption, is an example to follow. Cubans get their food with their containers, their rum in their bottles. They recycle everything they can and recover all that is recoverable (I've seen a Cuban pick up plastic cups in a hotel to wash them and use them in bars). I have no figures but I think that the rejection of a Cuban waste is at least ten times lower than a Western, knowing that Cubans live very well and have a life expectancy similar to those of Westerners. It should be noted that with this system Cubans have no access to the same products that Western countries.
Questions asked of students / Your answers to our questions are complete, we will only enrich with our experience, fat.
1 - Where does the ocean pollution?
Ocean pollution comes from human action because:
- Pollution of rivers
- discharges of domestic wastewater
- Industrial Waste
- oil spilled in the accidents occurring during extraction or during transportation of hydrocarbons
- marine debris such as waste plastics and synthetic
because marine pollution comes mostly lands, and especially rivers. Republic Dominican Republic, Santo Domingo river lay waste so that the marina, the river level, is protected by nets to prevent waste from returning.
2 - How many tonnes of waste are thrown away each year to the water?
Each year 20 billion tons of waste are thrown into the water:
- 150 000 tonnes of oil
- 1.8 million tons of toxic
- ; 6 million tons of pollutants from rivers
- 200 000 tonnes of oil dispersed in the air that falls into the ocean with the rain.
3 - What is the life of waste dumped in the sea?
Depending on their nature, waste take between three weeks and 1,000 years to degrade, some even indefinitely degradation.
Examples:
- newsprint: 3 to 12 months
- plastic bottle: 500 ans

Certains déchets mettent du temps à se dégrader mais ils ne font « pas de mal » à environnement : verre, papier et métal. Pour nous le poison des mers est le plastique : on en retrouve partout : dans la mer, sur les plages, dans l’estomac des poissons… en effet il se dégrade trop lentement (500 ans c’est l’équivalent à la découverte de l’Amérique) et il flotte (et donc on le retrouve OBLIGATOIREMENT SOMEWHERE). Some other wastes degrade even more slowly, but pose no threat to nature and do not cause visual pollution on the coast, if they are thrown away from the coast.
Here are the data we have: Source: "Questions of marine curious"
Paper: 2 to 5 months
Orange Peel 6 months Milk Carton
: 5 years
Tin: 10 to 100 years
Plastic bag: 450 years Aluminum Cans
: 200 to 500 years
plastic bottle: 100 to 1000 years
Glass bottle: 4000 years
4 - What is the most dangerous substance?
Plastic is the most dangerous substance. Indeed, the fish can eat the plastic bags that choke them.
summit We completely agree ...
5 - What pollutes the most in a boat? And on a sailboat?
What pollutes the most in a boat is oil.
And on a sailboat Waste Man.
Commercial boats reject a large portion of their waste in the sea (the cleaner), it is tolerated because it is small compared to emissions from the land.
On a sailboat, despite our efforts, we pollute too. On the one rejected by the engine some gas in the sea and on the other hand there is a pollution coming from the degradation of the hull of the boat and cleaning products we use.
6 - What is found on desert islands uncleaned?
There are all kinds of waste discharged into the sea and have a term of degradation or long (waste plastics and synthetic) and shipwrecks.
From plastic ... some islands we visited were deserted and no one is there to clean the edges of the hit on the beach is ALL products found floating: mainly plastic, all out (bottles, caps ...), sealed bottles, light bulbs, clothes ... it is difficult to list everything, just need to realize that any product returned to the sea to land somewhere.
