1. A waste management method to monitor and control emission of CO₂and CH₄from a waste collection system comprising a plurality of waste bins each waste bin having a waste bin housing and a lid on top of the waste bin housing, a plurality of sensors, a plurality of waste vehicles and a waste collection facility, wherein each waste bin of the plurality of waste bins has at least one sensor of the plurality of sensors, wherein the sensors and the waste vehicles are in wireless communication with a cloud server, comprising:

measuring, by the plurality of sensors located in each waste bin of the plurality of waste bins, a bin methane amount, a bin humidity, a bin waste level and a bin temperature with a methane sensor, a humidity sensor, a waste level sensor and a temperature sensor, respectively, each located under the lid of the waste bin;

determining, by a location receiver located in each waste bin, a bin location of each waste bin;

transmitting, by a sensor wireless communications transceiver of each of the plurality of sensors, the bin methane amount, the bin humidity, the bin waste level, the bin temperature and the bin location to the cloud server;

receiving, by the cloud server, the bin methane amount, the bin waste level, the bin humidity, the bin temperature and the bin location from each of the plurality of sensors;

recording, by the cloud server, a timestamp of the bin methane amount, the bin humidity, the bin waste level, the bin temperature and the bin location;

transmitting, by the cloud server, the bin methane amount, the bin humidity and the bin temperature of each waste bin to a first processor;

receiving, by the first processor, the bin methane amount, the bin humidity and the bin temperature of each waste bin and an allowable methane amount;

transmitting, by the cloud server, the bin waste level and the bin location for each waste bin and the timestamp to a second processor;

receiving, by the second processor, the bin waste level and the bin location of each waste bin, the timestamp and an allowable waste amount;

generating, by the first processor, a first time estimate to reach the allowable methane amount based on the measured bin methane amounts and the temperature of the plurality of waste bins;

transmitting, by the first processor, the first time estimate to a third processor;

generating, with the second processor, a second time estimate to reach the allowable waste amount based on the measured bin waste levels of the plurality of waste bins;

transmitting, by the second processor, the second time estimate to the third processor;

measuring, by a carbon dioxide sensor located on each waste vehicle of the plurality of waste vehicles, an amount of carbon dioxide generated by each waste vehicle per unit time;

determining, by a waste vehicle location sensor located on each waste vehicle, a location of the waste vehicle;

determining, by a waste vehicle methane sensor located on each waste vehicle, an amount of methane emissions of the waste within each waste vehicle;

transmitting, by a wireless transceiver of each waste vehicle, the amount of carbon dioxide, the location of the waste vehicle and the amount of methane emissions to the cloud server;

transmitting, by the cloud server, the amount of carbon dioxide, the location of each waste vehicle and the amount of methane emissions of each waste vehicle to the third processor;

receiving, by the third processor, the first time estimate, the second time estimate, the location of each waste bin, a set of parameters which determine the weighting of the first time estimate and the second time estimate, a number of waste vehicles available to empty the waste bins of waste, the amount of carbon dioxide generated by each waste vehicle per unit time, the location of each waste vehicle, and the amount of methane emissions of each waste vehicle;

generating, with the third processor, a collection schedule and a waste vehicle route for each of the plurality of waste vehicles based on the first time estimate, the second time estimate, the location of each waste bin, the weighting of the first time estimate and the second time estimate, the number of waste vehicles available to empty the waste bins of waste, the amount of carbon dioxide generated by each waste vehicle per unit time, the location of each waste vehicle, and the amount of methane emissions of each waste vehicle;

transmitting, by the cloud server, the collection schedule and the waste vehicle route to a database management system (DBMS);

transmitting, by the DBMS, the collection schedule and the waste vehicle route to each waste vehicle;

receiving, by the wireless transceiver of each waste vehicle, the collection schedule and the waste vehicle route;

transferring, based on the collection schedule, the waste from the plurality of waste bins into the plurality of waste vehicles, wherein each waste vehicle is travelling on the respective waste vehicle route, and

emptying the waste from each waste vehicle into the waste collection facility according to the collection schedule.
