Oil Palm Waste

This chapter presents the design and development of an economically and technically feasible small-scale oil palm waste shredder to contribuite to oil palm waste management. Most available oil palm waste shredders are unaffordable due to high initial investment cost, large, heavy and unportable, which have been the drawbacks for small and medium enterprises to participate in the industry that relates with oil palm waste management. To address this issue, a low-cost and small-scale oil palm waste shredder were designed and produced. The central design concept deduced is to compromise acceptable efficiency with an affordable price by integrating all mandatory components of oil palm waste shredder into a comparatively small and portable support structure. The innovations made in the design are size reduction and adoption of double-shafts cutters with seven jaws technology. Preliminary calculations supported the design. The cutting force produced is up to 19.45kN with safety factor of 4.5. This design can handle other oil palm wastes as oil palm frond is harder than other oil palm wastes.

There is a growing debate surrounding the contradiction between an unremitting increase in the use of resources and the search for environmental sustainability. Therefore, the concept of sustainable degrowth is emerging aiming to introduce in our societies new social values and new policies, capable of satisfying human requirements whilst reducing environmental impacts and consumption of resources. In this framework, circular economy strategies for food production and food loss and waste management systems, following the Sustainable Development Goals agenda, are being developed based on a search for circularity, but without setting limits to the continual increase in environmental impacts and resource use. This work presents a methodology for determining the percentage of degrowth needed in any food supply chain, by analyzing four scenarios in a life cycle assessment approach over time between 2020 and 2040. Results for the Spanish case study suggested a degrowth need of 26.8% in 2015 and 58.9% in 2040 in order to achieve compliance with the Paris Agreement targets, highlighting the reduction of meat and fish and seafood consumption as the most useful path.

The purpose of this chapter is to investigate and determine the most appropriate strategy according to the results of applied methodologies and literature about waste management for the textile sector. In this research, improvement of this concept for textile sector in Turkey has been implemented by using SWOT analysis integrated with AHP framework. Based on this, the most appropriate strategy has been chosen for this industry. According to this destination, SWOT analysis has been applied and alternative strategies have been determined which are based on green production and waste management of textile products for this sector. Then this SWOT matrix has been converted into a hierarchical structure. Thus, AHP model of this application has been formed with this perception via this methodology. Consequently, determination a management strategy within environmentally oriented production for this industry will be provided to contribute the environmental sustainability. Also, this study will be given a point of general view and approach for the importance of green production and consumption.

The Impact

Educational institutions and, specifically, university campuses are large energy consumers and waste producers. The impact of university campuses on the local waste management increases with decreasing the size of the city/town where universities are located. Following the growing interest of the scientific community on the research for strategies to improve the environmental sustainability of educational institutions, this paper aims at proposing specific parameters to 1) measure the performance of university buildings in waste management, 2) detect anomalous situations that require improvements and 3) implement ameliorative actions. Specifically, parameters like the per-capita or surface-specific waste generation could help identifying the structures that may require primary interventions. With reference to the case of a medium-size university, the paper points out the advantages of the punctual tariff system for waste management adopted by the local utility company and critically analyses its weak points. Overall, this system offers great opportunities for improving waste management and for cost savings, but requires careful management policies by public institutions.

AbstractA multi-floor manufacturing in residential districts of huge city promotes decongestion of urban traffic and satisfy the population’s demand for essential goods. City manufacturing and its supply chain entail several challenges related to the sustainable development of a large agglomeration. Environmental problems impose significant constraints on such manufacturing activities and production waste in the urban environment poses a real problem that needs to be addressed by special research. This paper discusses integrated sustainable production waste management for a city multi-floor manufacturing cluster, consisting of a group of production buildings and a supporting logistics node. In line with the theory of integrated sustainable waste management, three key components are addressed: waste management stakeholders, components of the waste management system, and the technical, environmental and legal aspects of a city multi-floor manufacturing cluster. The goal of the paper is to develop a concept for a model of environmental sustainable waste management in a city multi-floor manufacturing cluster, aimed at ensuring the system safety: human - technical facility - environment. This model can serve as a basis for the development of appropriate logistics chains for production waste management considering their hazardousness indicator. The versatility of the model will allow it to be widely used, and when its stages and working principles are embedded in the practice of city multi-floor manufacturing, proper control over the waste management process can be achieved. The application of the proposed model of integrated sustainable production waste management in the practice of the city multi-floor manufacturing clusters will contribute to the environmental sustainability of its operation.

One of the challenges of Lagos State is efficient and cost-effective solid waste management. This paper focuses on progress made in waste management operations in the State. An assessment to know how waste generation, collection, transportation and disposal have put demands on state resources, and its physical infrastructure was carried out. The state generates about 12,000 metric tons of waste daily (0.72kg/person/day). Due to limited budgetary allocation, the state government instituted the Lagos State Waste Management Authority (LAWMA) to perform supervisory roles and charged with the implementation, advocacy, monitoring and enforcement of waste management policies. As part of its roles, the agency enlisted Private Service Providers (PSP) for the purpose of appropriate billing of waste services. LAWMA centrally collects revenue and remits agreed portion of 60% of waste charges to individual PSP accounts in accordance to estimated waste collected. The state is focused on resource recovery programs such as composting, land filling and pelletizing of plastics and nylons. The implications (environmental, economic, social and financial) for managing solid waste gives credence to the renewal campaign for resource conservation and environmental sustainability. Thus, the 4 Rs of waste management – Reduction, Reuse, Recovery and Recycling are being demonstrated through establishment of compost production plant, championing of Waste-To-Wealth Initiatives and Renewable Energy (RE).
