The design was conducted using a new philosophy developed by manipulating Reed’s Plant Layout Procedure, Apple’s Plant Layout Procedure, Muther’s Systematic Layout Planning Procedure and Nadler’s Ideal Systems Approach with my own input. The plant will convert waste glass into decorative glass tiles that can be sold in Trinidad and Tobago. The recommended land area for the plant is 30.23 m × 21.17 m and is to be located in the Point Lisas Industrial Estate. The total capital cost of the plant is $12,255,575.80 TTD and operating cost is $ 16 659.20 TTD a day. The plant’s design will essentially cut the rate of waste glass into the landfills by 30 tons/day. If implemented the plant would provide numerous benefits that will outweigh its initial construction and operating expenses. Various methods was employed to prove the plant’s feasibility, which included determining the percentage utilisation of the plant’s equipment, the percentage utilisation of the plant’s floor area by equipment, a cost benefit analysis, market analysis and etcetera. In the end it was determined that the plant will be a worthwhile venture and will surely make an impact on the country’s landfills.

It will assess how viable this solution is to reducing the manufacturing cost and time of products, and increasing the level of quality control and assurance. The report is primarily research oriented in which a feasibility study was conducted to answer the research question. A Cost-Benefit Analysis and SWOT Analysis was used, along with research on the T&Ts economy, plastic bottle exportation and key drivers in the packaging industry to determine the project's viability.

It indicated that the average significant wave height and wave period in the Caribbean is 1.62 m and 5.91 s, respectively, while the average total theoretical power capable of being absorbed from a wave energy converter is 7.4 kilowatts per meter of surface waves. Devices should be designed to withstand a significant wave height of 19.0 ± 2.8 meters (95% confidence) for a 1 in 100 year return wave. This was determined by performing various extreme wave analyses. Additionally, a design life of 30 years for a device would have a probability of exceedance regarding this return wave as 26%. Using two-dimensional wave spectra analysis for the resource study, the overall spectral width, directionality coefficient and direction of the maximum directionally resolved wave power for the region are determined to be 0.172, 0.74 and 42 • , respectively. It is expected that the combination of these information would improve the viability of a wave energy industry in the Caribbean and advance technological development.

Potential avenues for developers to exploit the available technology and allow them to evade barriers preventing advancement were identified. The results of the study indicated that combining wave energy technologies with other functional systems in society such as coastal protection and eco-tourism initiatives can lead to increased value proposition of projects and reduced costs. They primarily include the ministries and agencies of a government responsible for public health, infrastructural development, energy, trade, industrial development, tourism, education and agriculture in SIDS. Wave energy harvesting devices should be engineered as part of established industries and supply chain to incrementally advance technology development. When choosing an energy stream to be utilised, project developers, policymakers and stakeholders use the Levelised Cost of Energy (LCOE) as their critical metric. To determine the applicability of the system, the LCOE is compared to the societal benefits. The societal benefits can be quantified by combining the avoided costs with the economic benefits. Additionally, standards, regulations for ownership and maintenance and installation procedures should be developed for increased chance of technology development.

The use of an energy dense and accessible renewable resource like wave energy in the Caribbean region is important since most of the nations are small island developing states with limited or no natural conventional energy resources. As such, their economy, safety and security is often impacted significantly by decisions from the world's major energy producers and trade markets. The advancement of wave energy conversion within the region will also contribute to the reduction of greenhouse gas emissions as dictated within the Paris Agreement. This study was conducted via a detailed research of literature related to the topic and an analysis of key metrics. It was identified that though the Caribbean possesses some of the lowest levels of ocean wave energy in the world, due to other factors it can still be considered as one of the most practical destinations for wave energy harvesting.
