What to do with old phones
Cell phones from the 1980s and early 1990s were analog and used standards and protocols that are no longer in use. Since that frequency is possibly used in many countries, mobiles of that generation might still work. But it will depend on where you are. If you’re in the U.S., you’ll be out of luck.
Bell Phones introduced the first commercial push-button telephone on November 18, 1963. It was first installed in Carnegie and Greensburg, Pennsylvania, just outside of Pittsburgh. The push button telephone replaced the rotary dial telephone, which had been in use for decades.
Rotary dial mobiles were introduced to American consumers in 1919, said Sheldon Hochheiser, AT&T’s corporate historian, but were not widely used until the mid-1950s.
The first used less Direct Telephone was in 1892 in La Porte, Indiana, based on an 1891 patent by Almon Brown Strowger. In 1919 the American Bell Telephone Company initiated nationwide service for users controlled rotary dialphones.
Telephone to call
In the early stages of radio engineering, a hand-held mobile radio service was conceived. In 1917, Finnish inventor Eric Tigerstedt filed a patent for a “Folding pocket telephone with a very thin carbon microphone.” Early predecessors of cell phones include analog ship and train radio communications. The race to create portable telephone devices really began after World War II, with developments taking place in many advanced countries.
Advances in mobile telephony have been charted in successive “generations,” starting with “0G” (zero generation) services, such as Bell Systems Mobile Telephone Service and its successor, Enhanced Mobile Telephone Service. These “0G” systems were non-cellular, supported a few simultaneous calls, and were very expensive.
In 1991, the second generation (2G) of digital cellular technology was launched in Finland by Radiolinja, on the GSM standard. This sparked competition in the sector, as new operators challenged the existing 1G network operators. This technology became increasingly popular in the second half of the decade.
Where cell phones are thrown away
Green Points with Attention: There are a total of 47 stations located in squares and parks, with attention in charge of an operator trained to provide information and advice to neighbors on recycling. They operate from Wednesday to Sunday from 12 to 8 pm, and in addition to receiving recyclable materials, they also receive used vegetable oil, packaged in clean and dry plastic bottles.

The Green Dot Mobile goes around the neighborhoods to collect WEEE (waste electrical and electronic equipment). It is mounted on a van specially adapted to receive electronic materials. It operates in the squares and parks where the fixed Green Points are located, where recyclable materials such as paper, cardboard or glass are taken. Each resident can deliver up to three units with their accessories.
The Chamber of Environmental Managers calls for increasing waste recovery goals in the country as a requirement to comply with the best practices of the Organization for Economic Cooperation and Development (OECD) in this area.
In the case of used tires and residual (burned) oil, the recovery rate does not exceed 20% of the waste generated by the country, while in OECD countries that rate is around 70% or more.
“In general, Costa Rica is well below OECD waste recovery rates. We do not want to coexist with waste, we want as much of it as possible to be recovered and transformed into other products,” warned Marlon Cruz, President of the chamber.
This situation prevents an adequate development of the market for recoverable products, since the amount of materials that are recovered is very limited and hinders the development of productive activities in the market related to integrated waste management.
