Uncertainty in emissions from brick manufacturing is a major concern and more primary monitoring based datasets are required. This study presents latest emission factors for continuous fixed chimney bull trench brick kilns (FCBTK), which is the main technology used for brick production in India. Stack monitoring of kilns in a typical brick manufacturing cluster in India is carried out to monitor emissions of pollutants like PM, SO2 and CO. Average concentrations of PM, SO2 and CO in the stacks are measured to be 172±76, 114±47 and 484±198 mg/Nm3, respectively. Monitored stack concentrations are used to compute emission factors based on brick production and fuel consumption activities in the cluster. The computed emission factors across different kilns ranged between 0.81-1.18, 0.57-0.71 and 2.07-2.80g/kg of fired bricks for PM, SO2 and CO, respectively. Corresponding emission factors per unit of coal used in brick kilns are found to be in the range of 13-29, 9-15, 40-56 g /kg for PM, SO2 and CO, respectively. The differences in emission factors are mainly due to variations in the quality of coal used by different kilns. Good correlations were observed between changing calorific values, ash and sulphur content of coal and emissions monitored in the kilns. These new factors can be used for improvement in emission inventories and thereafter modelling results for the region.
Review on modeling of coal blends for prediction of coke qualityJorge Madias
The operation of blast furnaces with coal/natural gas injection requires high coke quality. For lowest coke cost while keeping the necessary coke quality, the choice of coals and the formulation of the blend is a very important issue. A widely utilized tool for blend design is modeling, preceded by coal characterization and followed by pilot oven testing. In this paper, the development of models is reviewed, based on public literature. Three main stages are taken into account, form the sixties to current times..

Study on Characteristics of Geopolymer Concrete with E-WasteIOSRJMCE
The usage of industrial by-products in construction industry can be reduced the pollution effects on environment. Geopolymer concrete is a concrete in which Portland cement is fully replaced by fly ash and GGBS (Ground granulated blast furnace slag). The present study covers the use of E-Waste as partial replacement of fine aggregate in Geopolymer concrete. Sand is replaced with E-Waste at 10, 20 and 30 percentage.Alkaline liquids used in this study are the solutions of sodium hydroxide (NaOH) and sodium silicate (Na2SiO3). Molarity of sodium hydroxide (12M) is considered. Fly ash and GGBS were used in the combination of 90 and 10 percent respectively. This study conducted to know the compressive and tensile strengths of Geopolymer concrete with E-waste and to compare the same with Geopolymer concrete. It has been revealed that 20 percentage replacement with E-Waste attained higher strength than the normal Geopolymer concrete of M40 grade
Cement refers to the commodities that are produced by burning mixtures of limestone and other
minerals or additives at high temperature in a rotary kiln, followed by cooling, finish mixing, and

materials together. The most commonly produced cement type is "Portland" cement, though
other standard cement types are also produced on a limited basis.
Cement plants produced 99.8 million metric tons of cement. Worldwide production accounted
for about 2.5 billion metric tons. As with most large manufacturing industries, by-product
materials are generated. These industrial by-product and waste materials must be managed

- Very Low Running Cost
The Petroleum Coke also known as Petcoke, has several remarkable features from the usage point of view that are:
Petcoke can be a good replacement of coal/lignite.
It can be used in blend form along with coal/lignite or 100% in AFBC/CFBC boilers.
Ash content in Petcoke is much lower than coal/lignite. Hence particulate emissions are always lower as compared to coal.
All About Pet Coke
What is Petcoke ?
Cocking is a thermal cracking process characterized by long residence time and the production of petroleum coke (Petcoke), a heavy carbon residue. Petcoke is produced by thermal cracking of vacuum residue that is produced from crude oil.
In a petroleum refinery, atmospheric and vacuum distillation processes remove from the crude the oil the components that boil up to about 500oC. The distillation process separates the lighter part of the crude oil into fractions which are then processed into useful refined products such as LPG, petrol, kerosene, diesel, etc. The part of the crude oil which does not boil off during the distillation process even under vacuum is known as the vacuum reside. The vacuum residue consists of heavy, viscous, complex hydrocarbon molecules.
The coking process converts the vacuum residue into gas, liquid and solid products. In delayed coking, the heavy feedstock is heated in a tube still and pumped as rapidly as possible to insulated drums where it the large molecules are cracked into smaller molecules and residue, producing gas, liquid products and coke. The term 'delayed' comes from the delay between heating and coking. As coke buiilds up in the drum, the lighter products of cracking are recovered as overhead vapours and are taken to a fractionator for separation into various products.
Petcoke yield is mainly dependent on the carbon content of the feedstock, while the structural quality of the Petcoke is influenced chiefly by the type of feed, i.e., virgin crude or cracked products. Fuel grade Petcoke is produced from vacuum residues that have high sulfur contents. High sulphur Petcoke is used as fuel whereas low sulphur Petocoke is used in producing anodes.
Fuel grade Petcoke generally replaces iignite and coal.
The role of material in fertilizers industries with energy savingPremBaboo4
In Fertilizers industries the material plays a very important role. Right material can save energy as well as plant life and wrong selection of material may lead to catastrophic failures and outage of plants & even loss of Human lives, Right selection of material leads to long life of plant. In urea plant very corrosive chemicals are used for urea production. The raw material of urea plant is Ammonia and Carbon Dioxide gas which makes very corrosive chemical ammonium Carbamate. For reduced corrosion passivation air is used in reactor as well as stripper according to material of selection different quaintly of air is used. Controlled and less quantity of passivation air is required for Titanium and Zirconium material and hence saving of energy because the huge amount of ammonia is waste with venting of inerts, i.e. saving of energy and environments also. Passivation oxygen given in CO2 is directly proportional to ammonia losses in MP section. This paper intended how to increase life of urea reactor liner and energy saving with low passivation air and high N/C ratio, Ammonia is the noncorrosive and ammonia to CO2 Ratio is an important parameter for process optimization occurring less losses and less explosion probability in urea reactor because it affects the amount of produced urea and corrosion to the material in the reactor. Generally we are using urea reactor liner 316L (urea grade), now adopted 2RE69 for large capacity plant (world largest) and Duplex stainless steel.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.

11. Environmental load of Finnish ferrous and nonferrous
metallurgical industry – Future challenges
In ferrous industry main raw materials are oxide ores and in nonferrous
industry sulphide ores
Earlier sulphur dioxide was main problem in nonferrous metal manufacture;
now the main problem is a huge amount of unutilised solid wastes
High electric energy demand in electrolysis of copper, nickel and zinc and
ferrochromium and stainless steel manufacture
The main problem of ore based ferrous industry is CO2 emissions
Specific CO2 emissions (tons per produced ton of steel) of Finnish steel
industry are one of the lowest in the world
The major problem when using more steel scrap as a raw material will be the
contamination of steel by tramp elements
Utilisation of some dusts, slimes and sludge from ferrous industry is waiting
for economical solutions
12. Harjavalta industrial park as
an example of an industrial
ecosystem when developing
environmental friendliness of
carbon steel
Basic principle: “The primary production
chain of the ore based steel making is
not disturbed (Pöyliö et al. 2002)”
=> So, there is ahead a mega jump in
technological, economic and ecological
efficiency by totally eliminating waste
streams and fully exploiting synergies
with other related industrial technologies.
(Szekely 1996)
Heino 2006
13. Industrial ecology applied to carbon steel manufacture
More efficient use of own iron residues
(dusts, scales and sludge = waste oxides)
Use of iron residues from other industries
(Scrap, slags, roasting residues)
Use of secondary or bio based energy
sources and reducing agents (Plastics, tar,
heavy oil, tyres, wood, etc.)
More efficient use of slags in cement
industry, in road construction and agriculture
to replace virgin raw materials
Low heat energy utilization in district
heating, in greenhouses or somewhere else
in the surrounding community.
Coke oven gas can be converted into H2,
which can be fed into fuel cell battery for
automobile or chemical industry
Utilisation of carbon monoxide as a raw
material of formic acid manufacture
Better energy efficiency with the aid of
energy integration included pinch
technology, etc.

INTRODUCTION
Natural reserves of coking coal are limited and the standards for blast furnace iron
making are becoming increasingly strict, encouraging steel producers to implement
environmentally friendly and economical processes.
The production of high quality coke requires a better control of its properties (e.g.,
reactivity and strength) as well as sustainable and economic management of coke
oven gases (H2 ~ 58.5% and CH4 ~ 23.8% as a main utilisable components).
Because of the limited source of coking coal, it must be found new ways to
substitute the virgin raw material with other appropriate renewable or secondary
organic compounds.
Without large investments costs to extra treatment plant twaste plastics charged in
coke ovens can be used as a secondary source of hydrogen, a fuel, a reductant, a
carburization agent and a structural support used in a BF thus substituting virgin coal
and thus decreasing carbon dioxide emissions.

15. INTRODUCTION TO PLASTIC COKE RESEARCH IN EFBF
Without large investments costs to extra treatment plant waste
plastic can be processed in coke ovens to be used in blast furnace as
structural support, carbon based reductant, carburization agent, and
fuel for the hot iron metal.
By-products of coking process (H2, hydrocarbon oil, and CH4) can be
used in other more valuable purposes.
Virgin coal will be substituted and CO2 emissions reduced.
16. PLASTIC COKE RESEARCH
To study how coking process proceeds when coking coal without and
with varying amounts of plastics.
To investigate coking process when changing the amount of the
plastics among the coking coal.
To produce different type of plastic-free and plastic-bearing coke for
analysing and testing.
To investigate how plastics and their amount affect the porosity and
strength of the coke and to define is there any maximum limit to the
amount of the plastics.
To measure the coke gas composition when coking coal without and
with varying amounts of plastics.
17. The coal-to-coke transformation takes place as follows:
The heat is transferred from the heated brick walls into
the coal charge with the following consequences:
1. From about 375°C to 475°C, the coal decomposes
to form plastic layers near each wall.
2. At about 475°C to 600°C, there is a marked
evolution of tar, and aromatic hydrocarbon
compounds, followed by resolidification of the
plastic mass into semi-coke.
3. At 600°C to 1100°C, the coke stabilization phase
begins. This is characterized by contraction of coke
mass, structural development of coke and final
hydrogen evolution.
4. When the plastic layers have met at the center of
the oven, the entire mass has been carbonized.

21. EXPERIMENTAL
Metallurgical coke was prepared in laboratory scale coke ovens by coking three
common coals (RI, EV and BU) without and with most widely used plastic polyethylene (HDPE, (C2H4)n).
Plastics and coals were grinded to < 5 mm.
In mini coking process samples were warmed up to 1200 ºC.
Coke compression strength was measured by Zwick 100 kN Tensile test machine.
Image analysis by optical microscopy was performed to study textures and
porosity of coke.
ASAP 2020 Pore size analyser was used to measure porosity and surface area
(BET) of coke

24. Cold compression strength (kN/m2) of coke as a function of PE plastic 0 – 12,5 % addition in RI coal
25. RESEARCH RESULTS
No significant changes were observed in the cold strength results from 0 up
to 5% of HDPE plastics addition to the three different coals BU, EV and RI.
Below 5% HDPE plastics addition in RI coal the increase of mosaic texture at
the expense of isotropic texture compensates for the weakening effect of
increased porosity. Also rounded macro pores observed in texture analysis,
decrease the weakening effect.
Mosaic carbon texture in coke is usually less reactive with carbon dioxide
compared to isotropic carbon texture, thus improving the CRI and CSR
values of coke to be used in blast furnace.
The cold compression strength results of coke manufactured by adding the
most common plastic (HDPE) to Riverside coal were very encouraging.
Estimations are both coal-specific and plastic-specific and should be made
