/ecoeng/articles/rss en /ecoeng/article/heating-core-composting-vessel <p>Considering the present push towards greener industrial and residential activities, composting is once again a hot topic amongst Ecological Engineers. Since a uniform composting system is necessary to ensure the removal of pathogens and to keep the whole system at the same composting stage at a given time, it is essential to maintain a homogeneous temperature throughout the media. Therefore, in the quest to accomplish the latter, a design consisting of a heater core, copper tubing and heat recycling, was designed and tested.</p> Thu, 08 Aug 2024 21:03:25 +0000 Eyad Jamaleddine 635 at /ecoeng /ecoeng/article/phosphorus-cycling-and-organic-waste-management-island-montreal <p>Many human activities such as agriculture and waste management alter natural biogeochemical cycles. In many cases, they create linear flows of nutrients that can be energy intensive and lead to negative impacts on surrounding ecosystems.</p> Thu, 08 Aug 2024 21:02:08 +0000 Jillian Treadwell 634 at /ecoeng /ecoeng/article/optimization-heat-extraction-compost <p>Thermophilic bacteria break down the substrate in compost which results in large amounts of heat energy as a bi-product. Research has been published to quantify this heat and also find a use for the energy released. In this research, Kayode uses finite element modelling methods to develop standards in which this extraction of heat can be optimized.</p> Thu, 08 Aug 2024 21:00:11 +0000 Kayode Nwanze 633 at /ecoeng /ecoeng/article/gas-emissions-compost <p>Brendan is investigating the effects of augmenting agricultural compost with biochar in terms of the biochars' ability to retain agriculturally-valuable and environmentally deleterious nitrogen-containing gases. The research is divided into the physical composting stage, and a supplemental phytotoxicity and effects on plant production stage. </p> Thu, 08 Aug 2024 20:49:16 +0000 Brendan Peachey 632 at /ecoeng
