Official estimates by EXPO S.p.A. talk about 20 million visitors that will lead to a consequent production by the entire exhibition of 17,000 tons of waste in just 6 months . These are important numbers generated by 100 hectares on which extends the entire site of Expo Milano 2015 .

By comparison, to help us understand the magnitude of these numbers , keep in mind that we are talking about an amount of waste equivalent to the one produced by the entire city of Milan in a month on an area of 18,200 hectares. The relationship between the two is impressive if we think of 100 hectares vs 18,200.

To all this, the enormous amount of waste already produced in the crucial phase of the months close to the opening of the exhibition itself must be added. During this time, working in total emergency, it has lost track of the actual quantity produced. Of course also in this case we speak of very high numbers.

120 tons of waste produced daily

The numbers are certainly of great importance. Millions of visitors are expected with daily peaks of up to 250,000 admissions to which are added also the 15,000 people who work daily within the site to ensure all services. 120 tons of waste will be produced in the peak days such as weekends to 70-80 tons produced in normal days.

The real challenge will be to collect and confer waste with the most modern techniques of recycling with the aim of recycling at least 70% of the waste produced. To do all this in the best way EXPO Spa found qualified partnership in the management of the collection to perform this daily task.

But since the European Directive on the Management of Municipal Solid Waste (link to our article) indicates as best practice the prevention and waste reduction at the source , we at Ecodyger wanted to bring our direct contribution. How? By equipping some catering facilities with our machines that will allow to reduce up to
90%, the organic waste produced. All at zero km , or the 90% of this discard will never become organic waste. Think of all the energy saved by avoiding the collection, transport and treatment of rejection once this will be conferred in its final destination, whether it be a landfill , an incinerator or a treatment plant for the production of biogas, compost, etc.

This results in huge savings in terms of CO2 emissions without forgetting that the solid residue remaining is a 100% natural fertilizer used in all the activities of horticultural farming . So this will be our important contribution designed to reduce waste in perfect symbiosis with the same official theme of EXPO “Feeding the planet, energy for life” .

20 tons of organic waste per day

Official estimates of EXPO S.p.A. talk about the total amount of waste produced without going into the details of the various categories of the collection; this happens because it is difficult to identify which are the habits of above 20 million visitors, one third of which are foreigners from many different countries of the world, with customs and habits completely different from each other, including regarding waste.

Let’s say that about 40% of the waste will be generated by visitors; 60% will instead be produced within the various exhibition areas, especially the food ones, operated by 145 different countries.

So, based on European standards (Eurostat), the wet waste is 34% of the total waste collected, even 30% during “normal” days, which means at least 20-21 tons of organic waste per day.

If the same was treated on the spot, the source would have an immediate reduction of the same waste of approximately 15 tons a day. Key figures that would rise up to 24 tons a day on the weekends with the highest turnout, with an average of waste equal and over 120 tons; some assumed to be up to 130 tons. One Ecodyger allows a structure such as a hotel, a restaurant, a school or company canteen, a hospital to save for itself and the environment up to 2000 kg per month!

Just think to the quantity of CO2 not emitted, the lower energy used and, given that one of the EXPO themes is “Energy for life”, we think we are on the right path….

In the coming weeks, we will bring you the actual testimony of our presence at EXPO . Hoping you can directly touch with hand our technology when you will wonder before you go: “Expo Milan, what to see?”
