“…In Bangkok, about 5% of the waste collected is recovered by the waste pickers at source, while the quantity of materials gathered by the collection crew varies between 1 and 6 tons/day and the amount of materials recovered by the scavengers at the dumpsite varies between 50 and 150 kg/person/day. Therefore, around 7.5% of the solid waste is recycled in Bangkok (Muttamara et al 1994). In Thailand, more than 1.5 million tons of MSW is recycled each year amounting to 11% of the total amount of waste generated.…”

The increasing municipal solid waste (MSW) generation along with the high fraction of organic waste and a common disposal of open dumping is the current scenario in many areas in Thailand. As a response to this problem, the country's Pollution Control Department (PCD) aims to reduce the MSW generation rate to less than 1 kg/capita/day, increase the collection efficiency, and improve the recovery of recyclables. For many years, more than 60% of the solid waste disposal system in Thailand has been carried out by open dumping. According to the survey conducted by this study, in 2004 there were 425 disposal sites (95 landfills; 330 open dumps) in Thailand and an estimated methane emission of 115.4 Gg/year was generated based on this practice. It has been estimated that the anticipated methane emission in Thailand will rise from 115.4 Gg/year to 118.5 Gg/year if the largest open dumpsites in provinces with no existing landfill are upgraded to sanitary landfill; and it will increase to 193.5 Gg/year if the existing sanitary landfill is upgraded to integrated waste management facilities. Moreover, Bangkok metropolitan have the highest methane emission (54.83 Gg/year) among all the regions in Thailand. The methane emission forecast of 339 Gg/year by 2020 (based on LandGEM methodology) provides a stimulus to create a comprehensive plan to capture and utilize methane as an energy source.

“…Fortunately, recyclebot technology has been developed that enables users to turn plastic waste into 3-D printing filament with lower costs and less environmental impact (Baechler et al 2013;Kreiger et al 2013Kreiger et al , 2014Zhong et al 2017;Woern et al 2018). Polymer waste, often from food and drink containers, is common in many developing communities (Muttamara et al 1994) and e-waste is becoming more predominant that can also be used as a feedstock (Zhong and Pearce 2018). Informal waste recycling is already conducted as an economic activity (Zia et al 2008) and now recyclebot technology enables the potential for fair trade filament or social plastic (Feeley et al 2014).…”

Self-sufficiency of 3-D printers: utilizing stand-alone solar photovoltaic power systems

A self-replicating rapid prototyper (RepRap) is a type of 3-D printer capable of printing many of its own components in addition to a wide assortment of products from high-value scientific or medical tools to household products and toys. There is some evidence that these printers could provide low-cost distributed manufacturing in underprivileged rural areas. For the most isolated communities without access to the electric grid, a low-cost alternative energy is needed. Solar energy can be harvested through a stand-alone photovoltaic (PV) power system specifically designed to match the needs of the RepRap. The voltage and current requirement for the printer demands the use of buck along with a bidirectional DC converters to ensure proper operation. This paper provides the design for a stand-alone PV-lithium ion battery power system with an efficient controller. Robust and agile PI controller schemes are utilized to efficiently maintain the distribution of energy through the power system. The system was defined with ordinary differential equations, simulated and tested for two operational conditions in MATLAB/Simulink. The results showed that the controller developed operates the system in a stable condition and the simulation shows steady acceptable behavior that makes this system highly suitable for hardware implementation.
