Mollusk Shell

This paper studies the utilization and management of the waste mollusk shell. The two major export countries of mollusk shell are the Southeast Asia’s Thailand and the Philippines. First, the aquaculture of oysters and bivalve shells has been studied as background understanding. The effect of the global climate change on farming and the consequences of farming on the nearby environment and neighborhoods have also been discussed. The utilization technologies on the waste shell are available on a small scale and not industrialized. This study offers an enabling context under which a suitable method can take action to solve the overflow waste shell problem, and at the same time, provide sustainable management.

Cockle Shell

A conspectus based upon a compelling topic, namely, versatility of cockle shell use in concrete to replace partially the natural coarse aggregates and river sand, which is yet to be investigated, is covered in this chapter. An introduction to enlighten the reader with this promising waste material precedes a review of environmental issues with cockle shell which would reduce harm to environment and preserve natural materials for future generation. Cockle trade is an important subtitle that covers cockle shell waste generation, research, and development related to the deployment on the use of cockle shell, processing cockle shell for making construction material are discussed in detail. Experiments were conducted, and the test data revealed that the use of cockle shell as partial replacement of coarse aggregates enhanced the strength of concrete and as partial replacement of sand improved the performance of mortar bricks.

Selection Of

Concrete houses have a higher social and economic status. This study provides another consideration for the selection of building materials (Wonorahardjo, 2008). There are several ways that can be used to make concrete lighter, including using lightweight aggregates, substituting coarse aggregates with foam agents, adding coconut shells and additives where coconut shell waste has not been used optimally. In this research, a lightweight concrete mixture made from additives 5M additive, foam agent and coconut shell using 3 kg cement composition. While the 5M additives variation of 3%, 5%, 10%, 15% of cement, 15 milliliters of foam agent and coconut shell of 1%, with consideration of the specimens for 28 days not soaked non-curing. The test specimen is made with a size of 15x30 cm. This study is to determine the weight, compressive strength of the lightweight concrete produced. The results of research on the use of additional 5M additives, foam agents and coconut shells cause concrete to be lighter and compressive strength decreases. The weight of light concrete at 28 days not soaked is 775 kg / cm3, while the quality of concrete is 22 kg / cm2.

Freshwater Consumption

The conservation and proper management of natural resources constitute one of the main objectives of the 2030 Agenda for Sustainable Development designed by the Member States of the United Nations. In this work, a hybrid strategy based on process integration is proposed to minimize freshwater consumption while reusing wastewater. As a novelty, the strategy included a heuristic approach for identifying the minimum consumption of freshwater with a preliminary design of the water network, considering the concept of reuse and multiple pollutants. Then, mathematical programming techniques were applied to evaluate the possibilities of regeneration of the source streams through the inclusion of intercept units and establish the optimal design of the network. This strategy was used in the shrimp shell waste process to obtain chitosan, where a minimum freshwater consumption of 277 t/h was identified, with a reuse strategy and an optimal value of US $5.5 million for the design of the water network.
