“…The vigorous gasification reactions occurred in the first 30 min, the conversions of ER were 0.195 and 0.75, respectively. This setting was similar to other researchers [21,43]. Figure 4 shows that the volume fraction of gas components changes over oxygen concentration at 650 • C. It is clear to see that the combustible components CO, CH 4 , and H 2 show a similar trend, these gases were consumed by excessive oxidation due to more oxygen content, while the trend of CO 2 is the opposite.…”

Municipal solid waste (MSW) gasification could be a novel method that shows the various advantages over traditional MSW treatments in China. Other research concluded that MSW gasification was operating by the assistant heat, and the gasification may occur under medium temperature. So, this study is aimed to investigate MSW gasification and pyrolysis behavior and analyze the syngas evolution and reaction mechanism. The MSW samples were collected in daily life and the experiments were carried out in a fixed tubular reactor below 650 °C. The effects of medium temperature and oxygen content on syngas quality were elucidated in depth. The results have shown that temperature can promote the syngas quality in the range of 550–650 °C, because the increasing temperature strengthens the reaction rate. The oxygen content should be controlled in a certain range, or oxidation reactions will be more prominent during gasification. The optimal gasification condition in this study was obtained at 650 °C and an oxygen concentration of 1.25%, the combustible gas yield and the lower heating value (LHV) of syngas of this condition were 0.296 L/g and 10.98 kJ/L, respectively. This study provides insights for MSW gasification under medium temperature, and a practical gasification system can be designed under a certain condition.

“…The authors of the investigation [31] have estimated close results that 312 kg/h of MSW are required to produce 107 kg/h of RDF, assuming that 50 % of total MSW are recyclables (ceramics, metals, plastics, glasses, etc. ), water flow in the separated MSW total flow is about 43 kg/h; actcording to real (actual) operation of MSW handling, there were considerable material losses in the milling (3 %) and briquetting (2 %) operations [31]. Table 3 shows a potential of about 1,213 kt/a of MSW which could be treated for RDF production.…”

Технологiя спiльного спалення вiдходiв у цементних печах зарекомендувала себе надiйним, ефективним та зручним методом утилiзацiї вiдходiв (побутових та промислових). Проте країни по всьому свiту зiштовхуються з наступними ключовими бар'єрами на шляху до впровадження технологiї сумiсної переробки вiдходiв у цементних печах: нечiтке законодавство, вiдсутнiсть фiнансової пiдтримки, сприйняття громадськiстю, тощо. Цi бар'єри можуть бути частково усунутi за допомогою заходiв, запропонованих у цьому дослiдженнi. Крiм того, сортування та переробка вiдходiв часто не проводяться систематично. Нацiональнi та мiжнароднi цементнi компанiї працюють iз сучасними печами, якi можуть замiнити частину викопного палива та сировини вiдповiдними потоками пiдготовлених вiдходiв, якi пiдлягають спiльному спаленню. Спiльне спалення вiдходiв, що не пiдлягають вториннiй переробцi, є надiйним варiантом закриття iснуючих прогалин для впровадження принципiв циркуляцiйної економiки. Ця технологiя широко використовується в рiзних країнах Європи, але з рiзним екологiчним впливом на навколишнє середовище. Отже, важливим є дослiдити екологiчний потенцiал цiєї технологiї, який є змiнним для рiзних умов морфологiї вiдходiв. Дослiджено потенцiйнi переваги впровадження технологiї спiльного спалення твердих побутових вiдходiв у цементних печах. Застосовано методику оцiнки викидiв парникових газiв для бiогенних викидiв при визначеннi переваг та екологiчного потенцiалу при впровадженнi технологiї. На прикладi української цементної промисловостi визначено можливiсть: зменшення споживання антрацитового вугiлля у виробництвi клiнкеру до 262 тис. т/рiк; запобiгання утворенню до 284 тис. т викидiв CO 2 екв/рiк вiд замiщення вугiлля. Для сектору поводження з вiдходами було визначено можливий потенцiал вiд спiльного спалення: утилiзацiя побутових вiдходiв до 1 213 тис. тТПВ/рiк; запобiгання утворенню парникових газiв до 111 тис. тCO 2 екв/рiк на звалищах. Цi висновки важливi для ряду країн, оскiльки ключовi бар'єри для здiйснення спiльного спалення вiдходiв у цементних печах є спорiдненими. Результати екологiчного аналiзу та запропонованi заходи щодо уникнення визначених ключових бар'єрiв впровадження технологiї можуть бути використанi для умов багатьох країн Ключовi слова: спiльне спалення, ресурсозбереження, цементна промисловiсть, викиди парникових газiв, ключовi бар'єри

“…Gasification is used to convert solid materials such as coal, coke, biomass and solid waste into a gas, with average composition 15-30% CO, 12-40% H, and 4.5-9% CH 4 . The lower heating value (LHV) of syngas is between 4 and 13 MJ/Nm 3 , depending on the oxidizing agent used in gasification, operating conditions, among other factors [34]. From the syngas gas produced, different chemical intermediate products can be obtained, with different industrial uses.…”

The contribution of this chapter is to deepen and widen existing knowledge on municipal solid waste (MSW) management by analyzing different energy recovery routes for MSW. The main aspects related to the composition of waste are addressed, as well as the technological routes for thermochemical and biochemical energy usage. Within the thermochemical route, incineration is currently the most utilized technology for energy recovery of waste, with generation of electricity and heat and also a decrease in the volume of the produced waste. Gasification and pyrolysis are alternatives for the production of chemical products from wastes. The biological route is an interesting alternative for the utilization of the organic fraction of MSW, as aerobic or anaerobic processes enable the production of biogas and of a compound that can be utilized as a fertilizer. Depending on the size of the population, composition of waste, and products to be obtained (energy or chemical), more than one technology can be combined for a better energy usage of waste.
