How can waste management technologies help you contribute to sustainable development?

WM, should align with the (SDGs) by giving priority to the waste hierarchy pyramid and tackling important aspects of the trio of life management (environment, society, and economy), through conceptual modifications which involves shifting attitudes. The importance on including the waste management process-technology within the principles of circular economy, in order to understand the waste hierarchy management more in depth, where and when to stop, to start for the next step. One of the steps must be co-processing, there is nothing to waste. Do not forget to set clear targets, provide sustainable incentives, and what is important investing in infrastructure and education.

We need to stop promoting false solutions and “high tech” answers that are usually very inefficient in dealing with waste. Waste prevention can be tackled through strong and robust product design criteria to phase out problematic solid waste materials. This should be followed by an introduction of a labelling system for transparency and holding polluters accountable. Finally, shifting away from single use and fast moving consumer goods culture towards reuse and refill systems, integrated in our infrastructure. Once we have these systems in place, waste would be reduced and once waste is generated, it has a much higher likelihood of being adequately recovered or disposed.

As tecnologias e o desenvolvimento tecnológico será a base do conhecimento necessário para a efectivação da prevenção de resíduos como eixo prioritário na hierarquia de residuos e para a sua monitorização. A rastreabilidade dos produtos, a sua capacidade de reutilização, a modelação de processos e produtos (ecodesign) e a alteração para um modelo de Buy a Service not a Product sustenta-se no desenvolvimento tecnologico em toda a cadeia de um produto e residuo.

One effective method for waste prevention is adopting the "3Rs" principle: Reduce, Reuse, and Recycle. Encouraging the minimization of waste generation through conscious consumption (Reduce), promoting the reuse of products and materials (Reuse), and facilitating recycling processes (Recycle) can significantly contribute to sustainable development by conserving resources and reducing environmental impact. Additionally, incorporating circular economy practices, where products are designed with a focus on longevity and recyclability, can further enhance waste prevention efforts.

Advanced waste management technologies enable the recovery of valuable resources from waste, such as metals, plastics, and organic materials. This promotes a circular economy by reusing and recycling materials, reducing the need for raw resource extraction. WTE technologies can convert waste into energy through processes like incineration or anaerobic digestion. This helps in reducing dependence on traditional fossil fuels, mitigating greenhouse gas emissions, and contributing to the generation of renewable energy. Implementing smart technologies, such as sensors and data analytics, allows for efficient monitoring and management of waste. This helps optimize collection route and enhance overall operational efficiency.

Waste management is of crucial importance to sustainable development. Waste production is intensified due to significant population growth, urbanization, and consumerism. The waste sector emits methane emissions, coming from the breakdown of organic waste in anaerobic environments. When broken down by source, the waste sector is split into emissions from solid waste and wastewater. Solid waste emissions from landfills and dumps represent the majority of methane emissions. Concurrent with the increase in waste management, smart waste management strategies are being developed through the application of intelligent and novel technological tools. These include interalias smart waste bins; AI recycling robots ,etc.

As a person living in Iran, the biggest problem I face every day is garbage collection. The easiest way to manage waste is to separate dry waste from wet waste. It is really worrying that such a small thing will not happen in 2023.

La collecte des déchets est une étape fondamentale dans le processus de gestion des déchets. Des technologies innovantes peuvent être utilisées pour améliorer l'efficacité, la durabilité et la gestion globale de la collecte des déchets. Voici quelques technologies liées à la collecte des déchets : -Systèmes de collecte intelligente : Les technologies de collecte intelligente utilisent des capteurs et des dispositifs IoT (Internet des objets) pour surveiller le niveau de remplissage des conteneurs à déchets. Cela permet d'optimiser les itinéraires de collecte en envoyant des équipes de ramassage uniquement lorsque les conteneurs sont pleins, -Véhicules de collecte intelligent

In numerous developing countries, the daily generation of waste poses a significant challenge, leading to vast landfill areas burdened with segregated and unsegregated wastes. A primary issue contributing to this situation is the inadequate availability of land for traditional landfilling practices. However, embracing the waste-to-energy principle presents a transformative solution to this problem. The potential game-changing aspect lies in the utilization of high-calorific value waste as a valuable source of fuel for steam power plants. By tapping into this resource, not only can the mountains of waste be substantially reduced, but an additional benefit emerges in the form of energy generation.

The novelty needs to be applied even in dealing with the waste. Waste-to-energy practices for example can be effective in dealing with the current municipal waste disposal towards a more sustainable future. Diverting waste from landfills and making the best use of black bags by converting biological waste through various processes into power and energy. One example we can bring here is Milton Keynes Waste Recovery Park (MKWRP) where they successfully supplies more than 10k homes with electricity by the use of organic waste, and there is many others that go innovative in re-reusing waste.

Separation of waste at the source is the most effective step in waste treatment, which makes the rest of the path smoother. Recycling and burning and turning waste into energy are the best solutions at a time when energy is very expensive.

Voici quelques-unes des technologies de traitement des déchets : Incinération : Les déchets peuvent être incinérés dans des installations spécialisées. Cette méthode génère de la chaleur, qui peut être convertie en énergie électrique. Méthanisation : La méthanisation, également appelée digestion anaérobie, est un processus biologique où les déchets organiques sont décomposés par des bactéries pour produire du biogaz, principalement du méthane. Ce biogaz peut être utilisé comme source d'énergie renouvelable. -Compostage : Le compostage est un processus biologique de décomposition des déchets organiques en un amendement du sol appelé compost.

Waste heat recycling is an additional option. for reuse of waste heat. This presents a climate-neutral energy source and can cut costs for steam generation, process heat, district heating, electricity or cooling. A waste heat stream can also be applied in food processing technologies such as food drying, further contributing to preservation methods and in a cyclic way, reduce / prevent wastage of food at source by proving a a preservation method to excess perishable biomass.

It’s quite straightforward for disposal Currently, we still predominately dispose our solid waste in dumpsites rather than landfills. We need to efficiently transition towards more sanitary landfills to reduce pollution resulting from dumpsites. Once we are sufficiently addressing that transition, we could then think about other capture technology that operate in landfills but the priority should be transitioning away from dumpsites. The process naturally would allow waste management system to capture more recyclables prior to compaction and burial of the solid waste

Il est important de noter que l'élimination des déchets doit être gérée de manière responsable pour minimiser les impacts environnementaux et protéger la santé publique. Les approches choisies dépendent souvent des types de déchets, de leur volume, et des ressources disponibles dans une région donnée. Les technologies émergentes continuent d'évoluer pour améliorer l'efficacité et la durabilité de l'élimination des déchets. En tant qu'environnementaliste, vous pouvez plaider en faveur de méthodes d'élimination des déchets plus durables et encourager des pratiques de gestion des déchets responsables -Enfouissement (décharge) -Biorestauration : -Valorisation énergétique : -Recyclage final

Electronic waste (e-waste) is the fastest growing solid waste stream in the world. E-waste contains multiple known and suspected neurotoxicants, including lead and mercury, that may disrupt the development of the central nervous system during pregnancy, infancy, childhood and adolescence. Some harmful toxicants from e-waste may also impact the structural development and function of the lungs. Developing countries are at a significant risk from e-waste pollution due to lack of adequate testing equipment and standards as well as lack of responsive technology to treat the waste to manageable state/ condition. Special consideration and attention needs to be given to e-waste in developing countries.

L'utilisation de ces technologies de surveillance contribue à une gestion plus efficace des déchets, à la prévention des problèmes environnementaux et à la promotion de pratiques responsables. En tant qu'environnementaliste, vous pouvez plaider en faveur de l'adoption de ces technologies et encourager la transparence dans la gestion des déchets pour garantir une meilleure protection de l'environnement. -Surveillance environnementale : La surveillance des paramètres environnementaux tels que la qualité de l'air, de l'eau et des sols à proximité des sites de gestion des déchets permet de mesurer les impacts potentiels sur la santé publique et l'écosystème. -Capteurs de remplissage de conteneurs -Applications mobiles de signalement des déchet

It is also helpful to ensure the compliance on the journey. Registering all the rides of the fleets with their tonnage, directions and the destinations and linking them with bins/containers and landfills is important for all types of wastes. It allows a better vision and control on the waste management system.

It is essential to build a Lifecycle and Waste Management System : by gathering data from sensors and APIs, companies can have a deep understanding and monitor their waste with Machine Learning. From technological issue it will become a transformation challenge with the change of processes and the way teams work. Let's make these technologies adopted! Data and AI Consultancies can help building a strategy and then develop a tailored solution.

As tecnologias de gestão de resíduos permitem às organizações uma melhor visibilidade das cadeias de abastecimento, trazendo maiores oportunidades de controle e inovação, e permite a criação e processamento dos dados necessários para atender às demandas complexas das cadeias de abastecimento circulares, como rastreamento de materiais, logística reversa...

Waste should be viewed for its potential use. Depending upon its composition, it could be fuel, ballast, or resource material. It presents in so many different ways there should always be consideration of its use.

Public education and promotion, I believe, are the most critical for waste minimization. Before recycling plastics bottles, for instance, we should wash them properly for better safety and hygiene of the workers of the waste collection companies. The mixing of dirty or infectious substances with the recycling waste would undoubtedly increase the risks of workers handling such waste. We could also imagine that the quality of paper to be recycled is worse in case it is wet with water, gel or other solutions when collected. We should never be selfish when joining such sort of waste recycling programs. We might need to adjust our living styles a little bit accordingly.

Bringing waste trading platforms to mainstream is another way to manage waste. This is more feasible in industrial waste sector as the waste profile and amounts are generally defined. Industry A's waste could be raw material for industry B. For example, sulfur containing waste from an industry could be used for vulcanization in tire industry.

Cada cuidad, país o región tiene sus legislaciones ambientales que contribuye con el alineamiento de la gestión de residuos. Varias de estas tienen en cuenta como deben ser administrados en el sitio (como parte de la segregación) los residuos peligrosos, especiales o urbanos; además de como deben ser tratados en su disposición final. En caso de no tener legislaciones claras en nuestro entorno, es posible guiarnos de lugares limítrofes para poder organizar y solucionar problemas que no estamos pudiendo visibilizar. A su vez es importante saber que existen varios entes/organizaciones internacionales que tienen en cuenta estas problemáticas diarias y ofrecen soluciones ante los distintos sistemas de gestión de residuos.
