Intensifying Waste Management on Guam: Insights from Consumption Behaviour and Composting Initiatives | Chapter 7 | Research Advances in Environment, Geography and Earth Science Vol. 7

 

This study presented the efficacy of knowledge-based resource-recovery management to transform municipal waste into a valuable soil conditioner. Guam is a small, isolated tropical island in the western Pacific with a population of over 160,000 people. Although population growth and life style have been shown to have strong effects on the character and generation of waste, very little is known about consumption patterns and behavior of the people of Guam in this regard. Currently landfilling is the only discard method available to the island. Rapid increases in the volume and variety of solid and hazardous waste as a result of continuous economic growth, urbanization, and industrialization are a burgeoning problem for national and local governments, which must ensure effective and sustainable management of waste. Placement of huge volumes of organic waste material in landfills not only causes environmental problems for the island but in fact constitutes loss of valuable resources that could be composted and made available for land application as a soil amendment in forest lands, farm fields, and home gardens. Composting on the other hand reduces both the volume and the mass of the raw material while transforming it into a valuable soil conditioner. Here we present some of the results of survey questionnaires that was developed and conducted over the past two years that is anticipated to help waste operating managers and decision makers to determine societal consumption behavior and residential life style as the first step toward development of an effective waste-management strategy for the island of Guam. In this regards, we also presented an example of a large scale composting method developed in Isfahan, Iran, for recycling of organic wastes of municipal origin. Different zero-waste management strategies and techniques have been developed and adopted in different countries [1], but the strategy used in the city of Isfahan, Iran, which includes large-scale mechanical composting as a major component is of particular interest to Guam and the neighboring islands in the Micronesian region.

Integration of IoT, Blockchain, and Machine Learning in Recycling: A Survey of Waste Management Innovations | Chapter 27 | Innovative Solutions: A Systematic Approach towards Sustainable Future

Over the past few years, the growing amount of garbage generated by households has become a major issue that is affecting society as a whole. The consequences of unmanaged garbage generation are extensive and include economic burdens, public health hazards, and environmental deterioration, from overflowing landfills to polluted waterways. In this endeavor, recycling becomes crucial since it provides a comprehensive answer to the intricate interplay of waste-related challenges. Recycling has the ability to lessen the negative consequences of household trash while also promoting environmental stewardship and community resilience since it diverts items from landfills and reimagines them as useful resources. This paper investigates and provides the reviews of the relationship between digital technology and recycling by analyzing various methods of recycling and social impact of current platforms. It also aims to provide a path for the future by spotting chances to use digital advances to promote sustainability and holistic wellness in the contemporary day. This investigation's insights highlight how important it is to combine digital technologies and recycling practices in order to effectively tackle the various issues that arise from home waste. Society may move towards a more sustainable future where waste is seen as a useful resource rather than a burden by utilizing the power of digital platforms.

Application of Mollusc Seashell as Aggregate in Concrete | Chapter 6 | Novel Perspectives of Engineering Research Vol. 3

 Recycling waste materials in cement-based products has been the subject of recent studies on sustainable construction. Large quantities of mollusk seashells are frequently discarded as rubbish along beaches or in landfills, bringing health and environmental problems including as pollution and vector breeding. Mollusc seashell waste is managed by recycling the seashell as a partial or complete replacement for natural aggregate in concrete. Cockle, mussel, oyster, periwinkle, and scallop shells have been utilised as coarse and fine aggregate replacements in concrete. The calcium carbonate content of mollusc seashells is similar to that of limestone-type rocks. Although mollusk seashells contain chlorides, sulphates, and harmful organic materials, their contents can be reduced by washing and boiling. The qualities of mollusc seashell concrete, as well as the treatment, preparation, and features of mollusk seashells, are covered in this chapter. The existing state, limitations, and future potential of mollusk seashell in sustainable concrete building are also discussed. Concrete's workability, density, and strength qualities all diminish as more seashells are replaced. Crushed seashell can be used as a partial fine aggregate in concrete up to 20% without compromising the density or strength of the concrete. As a result, mollusk seashells can be utilised as a secondary aggregate in concrete, especially in areas where large quantities of seashells are available.

Resource Recycling for Enhancing Farm Productivity and Profitability in Integrated Farming System under Rainfed Situation in Odisha, India: A Recent Study | Chapter 09 | Current Topics in Agricultural Sciences Vol. 2

 From April 2010 to March 2013, the current study was conducted in a 0.8 ha rainfed farm with two water sources: no pond/rainfed and pond/irrigated in five different blocks: Khajuripada of Kandhamal district (North Eastern Ghats Zone), Dhenkanal Sadar and Odapada of Dhenkanal district (Mid Central Table Land Zone), Golamunda and Narla of Kalahandi district (Western Undulating Zone) of Odisha The Rice Equivalent Yield (REY) in the Integrated Farming System (IFS) model farm was 31.92 q, compared to 3.78 REY in the conventional rice-greengram system. The net return in the IFS model was Rs. 1,61,148/-, whereas the conventional system yielded Rs. 11,631/-. In the IFS model, recyclable wastes of 3.3 t paddy straw, 3000 kg pond silt, 2129 kg poultry excreta, and 13 t mushroom were used as resources for various components. The efficient recycling of wastes increased the productivity and profitability of IFS models. Almost no trash was left to damage the environment or degrade the resource base, whereas waste in traditional systems was not properly utilised.
