THE PROBLEM AND ITS SCOPE

INTRODUCTION
Rationale of the Study

The disposal of plastics waste is one of today’s most pressing

environmental issues due to its low biodegradability and presence in large

quantities. Plastics are increasingly being used as packaging materials and in

products such as bottles, polythene sheets, containers, packaging strips, and

other items. As a result, plastic garbage is produced by a wide range of people

from industrial makers to home consumers. To avoid a pollution catastrophe,

many goods are made from reusable waste plastic. Waste reuse is significant

because it helps in the recycling and conservation of energy in the manufacturing

process, as well as reducing pollution and preserving non-renewable natural

resources. Using plastic waste in the material sectors is an eco–friendly way to

reduce the amount of waste incinerated in landfills. Plastic has been proved to

work in concrete studies, and this sort of material has become a prominent study

topic in recent years.

The use of eco-friendly blocks as a construction approach to alleviate the

problem of excess plastic accumulation in places that lack adequate waste

management systems. Other countries, including South Africa, the Philippines,

and few others, quickly caught on and adopted the idea. Rapid urban migration

has resulted in waste levels that are becoming increasingly unmanageable in

most southern African countries. Garbage management is a serious concern for

 2

public health and safety, according to the South African Development Community

(SADC, 2015), and it now faces three major challenges: "high volumes of waste,

low capacity to manage, and high costs involved in management" ("Waste

Management," 2012). Because local governments have been unable to

successfully address these concerns, most waste disposal has been privatized

across the region, with mixed results in some regions and worsening situations in

others.

As a result, researchers came up with this study to aid in the preservation

and protection of the environment by removing plastics from the environment,

preserving them, and repurpose them in new ways. Furthermore, with this

innovation people can help reduce the plastic waste pollution by using this eco-

friendly concrete block in building structures.

The objective of this study is to test the effectiveness of employing

shredded plastic waste in the production of concrete blocks. As an alternative,

the researcher will create a concrete block from common materials which

produce good quality and stronger concrete blocks. These materials are all found

in the locality. The output of this study is an eco-friendly concrete block for a

solution to plastic waste pollution.

Theoretical Background

Waste Management Theory (2004) and Zero Waste Theory (2009)

The study is based on Waste Management Theory (2004) by Green

Alliance and in addition to Zero Waste Theory (2009).

Theory Waste Management (2004) states that a unified body of

knowledge about waste and waste management, and it is founded on the

expectation that waste management is to prevent waste to cause harm to human

health and the environment and promote resource use optimization. Waste

Management Theory (2004) is to be constructed under the paradigm of Industrial

Ecology as Industrial Ecology is equally adaptable to incorporate waste

minimization and/or resource use optimization goals and values. (Pongrácz,

Phillips, Keiski, 2008).

Waste Management Theory (WMT, 2004) has been introduced to channel

environmental sciences into engineering design. It is an effort to organize the

diverse variables of the waste management system as it stands today. WMT is

considered within the paradigm of Industrial Ecology and built side-by-side with

other relevant theories, most notably Design Theory. Design Theory is a

relatively new discipline, still under development. Following its development

offers valuable insights about evolving technical theories. According to Love

(2002), it is crucial to theory development to integrate theories from other bodies

of knowledge, as well as the clarification of the definitions.

The Theory of Waste Management (2004) represents a more in-depth

account of the domain and contains conceptual analyses of waste, the activity
 4

upon waste, and a holistic view of the goals of waste management. The proper

definition of waste is crucial to constructing a sustainable agenda of waste

management. It is largely the case that current legislation attends to existing

waste. Definitions emerging from this condition may, however, conflict with the

goals of waste prevention, because something that already exists cannot be

prevented from arising. When material is assigned the label of ‘waste’, it will be

treated as such; consequently, despite its explicit wish of waste prevention,

implicitly, legislation essentially amasses waste. The inherent philosophical

implication of such definitions is that they are not able to facilitate a sustainable

waste management system. Therefore, new, dynamic definitions for waste and

waste management must be sought, which can explain why waste is created and

can offer an intrinsic solution to the problem. The Republic Act (RA) 9003,

otherwise known as the Ecological Solid Waste Management Act of 2000,

provides the necessary policy framework, institutional mechanisms and mandate

to the local government units (LGUs) to achieve 25% waste reduction through

establishing an integrated solid waste management plan based on 3Rs (reduce,

reuse, recycle).

The Zero Waste Theory (2009) on the other hand, states that other

materials will be used as resources in the lifestyle and practices to emulate

sustainable natural cycles. It was related in a way that the purpose of the crafting

of the eco-friendly concrete block is to help people in reducing their construction

cost and it shows higher workability and reduce environmental waste.

SUMMARY, CONCLUSION AND RECOMMENDATION

This chapter contains the summary, conclusion and

recommendation of the study.

SUMMARY

The disposal of plastics waste is one of today’s most pressing

environmental issues due to its low biodegradability and presence in large

quantities. Plastic has been proved to work in concrete studies, and this sort of

material has become a prominent study topic in recent years. The researchers

come up with this study to aid in the preservation and protection of the

environment by removing plastics from the environment, preserving them, and

repurposing them in new ways. The study is based on Waste Management

Theory (2004) by Green Alliance and in addition with Zero Waste Theory (2009).

The main aim of this study is to determine the effectiveness of the eco-friendly

concrete block as a substitute to the commercial concrete block. Survey method

was used in this study. To gather data, survey questionnaires were utilized by

the researchers. The study was conducted at G & N Hardware located at North

Poblacion, La Libertad, Negros Oriental. Data were analyzed using Paired

Sample t-Test. The level of satisfaction of the respondents on the Eco-friendly

Concrete Block got 3.31 or Very Satisfactory in terms of its efficiency,

compressive strength, density and appearance and the Commercial Concrete

Block on the other hand, got 3.22 or Very Satisfactory in terms of its efficiency,

compressive strength, density and appearance. The computed value is .558.

The p-value is 0.616 with 0.05 as the level of the significance. This implies that
 20

the null hypothesis was accepted since the p-value is greater than the alpha

value and the significant difference between the level of satisfaction on the Eco-

friendly Concrete Block and the Commercial Concrete Block was not significant.

CONCLUSION

With an alpha of 0.05, computed value of .558 and a p-value of

0.616 the data suggested to accept the null hypothesis since the p-value is

greater than the alpha value. The null hypothesis was not rejected suggesting

that there is no significant difference existing between the Eco-friendly Concrete

Block and the Commercial Concrete Block. Therefore, the level of satisfaction of

the 10 male construction workers from G & N Hardware in the effectiveness of

the eco-friendly concrete block and the commercial concrete block are the same.

These imply that Eco-friendly Concrete Block can be a good substitute to the

Traditional Concrete Block.

RECOMMENDATION

The researchers recommend the enhancement in making of the

Eco-friendly Concrete Block specifically to improve its efficiency and density. In

addition, the researchers commend that in the process of making the eco-friendly

concrete block future researchers should also make a commercial concrete block

to determine their differences in terms of measuring the ingredients that will be

used, its efficiency, compressive strength, density and appearance.
