There is an absolute need to adopt innovative technologies to improve energy efficiency with minimum possible environment emission and conservation of natural resources.

The Environment Protection Department of Punjab issued a notification that zig-zag firing (induced) technology brick kilns will be allowed and construction of old conventional technology shall not be allowed.

Sterilization Efficacy of Demolizer Technology for Onsite Treatment of Sharps and Other Regulated Medical Waste against Staphylococcus aureus, Escherichia coli, Candida albicans, Mycobacterium phlei and Bacillus subtilis Spores.

The German Lime Association is researching both carbon direct avoidance and smart carbon separation (SCS). Direct avoidance will require alternative fuels, and new kiln technologies using pure hydrogen or oxyfuel. Hydrogen can also be used with natural gas to reduce CO 2 emissions in natural gas-fired kilns. This will mitigate about one-third …

The technology has been known to reduce power consumption and cuts down carbon emissions hence improving the air quality. Bricks produced using zigzag technology are better in quality. Punjab Province is reportedly home to 7,896 brick kilns in total, most of which are located near urban areas. These kilns previously used energy …

Environmental Science & Technology has been certified as a transformative journal by cOAlition S, committing to a transition to open access in the future. If your research funder has signed Plan S, your open access charges may be covered by your funder through …

Regarding the type of kiln, previous studies on the environmental impacts of air emissions from different brick kiln technologies show that zigzag kilns and VSBK emit less CO 2 per kilogram of ...

Environmental Technology is an international, ranked, peer-reviewed journal which publishes original research contributions to scientific knowledge. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees.

Policy documents from the Department of Environment (DoE) were used to construct a chronological narrative of the technology mandate for the brick sector. Academic literature framed the policy goal by highlighting the benefits of switching to cleaner technologies, but avoided substantive discussion on the policy instruments for …

Energy efficient and clean, the Waelz Kiln technology is especially suited to the increasing demands of environmental laws being implemented globally.

To operate a brick kiln, mandatory environmental clearance certificate must be obtained from the regulatory authority Department of Environment (DoE), followed by a license from the district commissioners office ( ICIMOD, 2019 ).

Future studies should examine the extent to which owners are aware of modern kiln technology and assess the impact of education campaigns on their familiarity and comfort with using alternative materials for brick production and energy replacement.

The kiln is the heart of the cement-making process. Raw materials like limestone, clay, and sand must be heated to extremely high temperatures in a kiln to produce cement clinker. Kilns provide the intense heat needed to initiate the chemical reactions that convert the raw materials into clinker.

Emissions of PM from cement and concrete production are clearly areas in which appropriate policy, and implementation of existing technologies, can drive down undesired environmental burdens 16.
