Just a few weeks in the past, throughout his participation within the “Sustainable Development” discussion board organized by EL COLOMBINO, Mayor Federico Gutiérrez spoke concerning the challenges that Medellín faces to leap into the long run and develop into a mannequin and sustainable metropolis. the years to come back. And in that approach he talked concerning the massive mess that the capital of Antioquia has relating to the disposal of strong waste, declaring that solely the cultural transformation of the residents can reverse the state of affairs and he stated throughout his passing that he’s keen to analyze make the brand new applied sciences. he places on the world for Medellin to vary its outdated landfill mannequin which grew to become a headache.
A gaggle of Colombian consultants began an organization in america with a know-how known as plasma gasification that appears like one thing out of science fiction – however which already works in several components of the world – the mayor replied that he doesn’t must exit and spend assets in quest of this know-how as a result of he has the political will and the flexibility to separate himself from what all his predecessors had completed — burying rubbish to go away the issue to another person – they’re keen to construct a undertaking that won’t solely take away Medellín’s complications but in addition metropolis invoice breaking down your trash to show it into power.
Nelson Franco is a chemical engineer who co-founded and is CEO of WES Worldwide, and has managed initiatives for Exxon, Merck and Pfizer. He explains that though plasma gasification is the most recent know-how that present know-how affords for strong waste administration, it’s a comparatively easy thermochemical course of. It’s a development a plant fed completely with rubbish to that receives waste of every type, together with hazardous waste. When the waste enters, it reaches the primary reactor the place it’s dried, thermal degradation takes place (pyrolysis) and the gasification of that waste begins at a temperature between 800 °C and 1,000 °C. The gases generated there go to the second reactor the place the temperature rises from 3,000 °C to five,000 °C and the gases change to plasma. Lastly, this plasma is cooled in a warmth exchanger the place it’s lastly transformed to syngas, which is taken into account an excellent gas composed primarily of carbon monoxide (CO) and hydrogen (H2), which might energy generators that generate power transfer electrical. “We are able to say that We remodel a rubbish dump into the equal of an oil properly as a result of with the rubbish that is available in we produce gasoline like oil,” says Nelson. This complete course of generates business hydrochloric acid (HCl), metals for recycling and refined rock that’s extremely wanted within the development sector.
The large query is whether or not that know-how, which already exists in not less than 10 international locations, together with two enormous vegetation in China, is viable to copy in Medellín. Freddy Uribe, WES undertaking supervisor in Colombia, factors out that though they offered the undertaking to Emvarias lately, EPM, the Metropolitan Space and the Authorities now have a bonus they didn’t have earlier than: multilateral funding to development of gasification vegetation. . “We all know that many individuals are providing Emvarias or EPM supposed cutting-edge know-how, resembling waste incineration (very completely different from gasification), which is prohibited in Europe and america to generate furan and dioxins of their course of, extremely carcinogenic. However we additionally know that they’re proposals that come on the lookout for cash and our benefit is that there are already individuals who have arrange the funding,” he says.
The agency has been finishing the undertaking for a few years to make it viable in Colombia and Freddy asserts that the numbers they’ve present the break-even level by way of monetary closure. The development of a plasma gasification plant prices between 72 million {dollars}, to course of 100 tons per day, to 446 million {dollars} to course of 1,000 tons per day. Of their calculations, they’ve indicated that Medellín may have a capability of 1,000 tons per day, receiving solely 40% of all of the waste produced by the capital of Antioquia and solely barely greater than 30% of the day by day tons goes into the La Pradera landfill. day by day.
Nelson and Freddy clarify that the plant is succesful producing one megawatt per ton of rubbish and it could rely extra on the kind of waste (plastic and tires, for instance, generate extra manufacturing than natural waste). The monetary closure provides them a value of 10 cents per kilowatt. Vitality era could be the primary earnings, however it will additionally generate cash from the rubbish disposal cost, even cheaper than the charge presently charged to municipalities to obtain their rubbish in La Pradera (30 {dollars} per ton). As well as, as a result of it’s thought-about inexperienced power earlier than the world banks, the power generated by plasma gasification can promote carbon credit. For each ton of greenhouse gases that the plant prevents from getting into the ambiance, 3.7 carbon credit are emitted. To entry this market, one of many calls for of multilateral organizations is to ensure the inclusion of the recycling inhabitants, which is why in addition they think about a station the place formal recyclers promote on to them.
After granting the environmental license as a biomass power era undertaking, they point out that it will take 24 months to construct the plant. As soon as it’s in place, after paying the mortgage, the curiosity and the working prices, they declare that it will be capable to go away 100 million {dollars} internet per 12 months and, in accordance with the matrix they handle , 20 million {dollars} could possibly be according to Medellín as a associate if 20% of the undertaking is signed.
Medellín and the municipal areas they wish to affiliate don’t want funding to construct it, however they want the lot to construct the plant and the assure of with the ability to provide them with strong waste for 25 years, and that EPM (the proprietor of Emvarias, who ‘owns’ the rubbish of the town and the municipalities that eliminate it in Pradera) ensures the commercialization of the renewable power generated.
The plant should even be in an space with entry to interconnected energy networks. With these traits, in accordance with their evaluation, there are viable properties in a number of sub-regions of Antioquia (North and West, for instance), together with Pradera itself, between Barbosa and Donmatías, the place they’d be wanted round on 10 hectares or much less.
However Nelson reiterates that the very first thing wanted is the political will. They are saying that after sitting down with Emvarias to point out him the undertaking, they’re now within the technique of formally submitting the proposal with EPM, the Medellín Mayor’s Workplace and the Authorities and are ready for Mayor Gutiérrez, who as a result of it appears to be rising. chief to provide him a change in rubbish disposal in Medellín, listening to his proposal with the intention of stopping Medellín from dumping rubbish, accumulating well being and environmental issues and burying cash within the course of.
