When we buy a Christmas tree a thousand things come to mind: for how long, how was the pine seedling cared for until it sprouted into a tree, where did it grow, how was it transported to its destination? We can find answers to these with the help of the seller or the Internet. It rarely comes to mind that after Christmas, when a stripped donut, freed from a needle-shaped dress, finds itself on the street around a water crossing, what will its destination be.
Garbage trucks are picking up the Christmas tree torsos that have turned back to pine, we know that by now.
But then where do they put them?
Regarding the “action” in Budapest, we turn to the Metropolitan Public Area Manager, who collects and transports the pines in an organized manner after the holidays. This is not an ordinary logistical task,
since it is estimated that around 500-600 thousand pine trees will be placed on the streets at this time,
this amount must be treated and its recovery resolved. Yes, we are talking about utilization, because the trees do not end up in the garbage, they do us a good service, because thanks to the Main Distance and the FKF, we warm up with them, not for a short time.
“Dumping dumping” in the FKF experience
It will begin after January 6 and will last for a month and a half.
Residents of Budapest can choose from several options: they can place their trees next to the bins on the day of extraction, or they can be placed at one of the more than 250 designated collection points. However, care must be taken not to obstruct pedestrians, roadside parking, or car traffic.
Designated collection points are called
pine passages
Transport the Christmas trees.
In parallel, sooner or later, residential waste collection vehicles collect evergreens from residential properties, or collect large trees in a separate vehicle that would not fit in simple “garbage trucks”.
It’s very hot
The successful Christmas trees will be transported to the Budapest Waste Utilization Plant, which is the only waste-based communal power plant in Hungary.
Here 60 percent of the urban solid waste generated in the capital is incinerated. The Rákospalota plant can process 420,000 tons of garbage per year.
In the waste recycling plant, the weight of the incoming waste is first measured, the incoming pine trees are crushed and then transported to the bunker space, where they are mixed with the municipal solid waste by means of a 10-ton bridge crane, the so-called octopus. The ladle then feeds the mixture into the waste hopper of the boiler, which slides onto the measuring table, from where everything is pushed into the combustion chamber by the hydraulically operated measuring piston. In the combustion chamber, the air temperature sometimes reaches 850 degrees Celsius.
The contaminants are destroyed during the process and the wastewater is collected and sealed. Steam generated at more than 400 degrees Celsius enters the flue gas purifier, from where steam suitable for district heating is already emitted. The remaining amount is used to generate electricity through a turbine.
With the help of this steam, we heat our houses in Budapest and use electricity for lighting and electrical equipment.
The energy use of Christmas trees is therefore an environmentally friendly solution, since electricity and district heating are produced within the framework of so-called cogeneration. Produced at the facility
- thermal energy reaches about 76 thousand floors in Budapest in the form of district heating and hot water,
- and electricity provides the annual electricity demand of around 50,000 average Budapest households.
