CAUSE
PROBLEM
Inadequate solid waste disposal and management practices are one of the main
environmental issues that developing countries are dealing with. Solid waste has been a serious
environmental concern since the industrial revolution. (Pulp and Paper Technology, 2023).
Today, waste masses are a regular sight. Thrown trash is everywhere in the form of
decaying mounds that litter our landscape, contaminate our rivers, and contaminate our wells and
lakes. Trash has very successfully crossed the urban-rural barrier, such that even the notion of
a tidy village is no longer realistic.
As defined by the World Health Organization, solid waste is any kind of garbage, trash,
refuse, or waste material. It can be divided into different categories depending on where the
garbage is produced, such as municipal solid waste, health care waste, and e-waste. Municipal
solid garbage production exceeds 2 billion tons annually.
It can be divided into three categories including its place of origin, which involves
residential, industrial, commercial, building, or institutional; materials which can be organic, glass,
metal, plastic, paper, etc.; and potential for hazards, either it is infectious, radioactive, poisonous,
flammable, non-toxic, etc.
Depending on the biodegradability, solid wastes can be also classified as:
Biodegradable those that bacteria and other microorganisms can break down
(decompose) into their component parts. The primary biodegradable wastes include food waste,
manures, and crop waste. Methane gas may develop if the breakdown process is carried out
anaerobically (without the presence of air). Methane is a potent greenhouse gas that, in the
presence of an ignition source (such an electrical spark), can ignite if enough of it builds up and
it is there. In addition to unpleasant scents, the decomposition may also cause them.
Non-biodegradable
also known as inorganic, do not break down due to microbial activity. Plastic bags, scrap
metal, food and beverage cans, and plastic containers are some of these wastes.
According to whether or not they would burn, materials in solid wastes can also be
categorized as combustible or non-combustible.
The Philippines produces far more trash than can be managed by its solid waste
management system. With a population of over 100 million, the Philippines produces more than
21 million metric tons of trash each year. The weighted average per capita generation for the
nation is 0.4 kilograms, or about half a kilo. Considering the Philippines has generated a total of
21,4265,676 metric tons of trash as of the anticipated 2020 garbage last year. With an estimated
population of more than 12 million, the National Capital Region (NCR) is the largest creator of
trash.
Valdez (2023), in her report highlighted legally required requirements about these trash
diverting practice solid waste management goal, materials recovery facilities, 10-year plan, and
disposal facility—all of which continue to be badly followed, especially by LGUs. Waste diversion,
according to her definition, is the practice of reducing or eliminating the volume or amount of solid
waste produced by waste facilities. According to Section 20 of RA 9003, which mandates the
establishment of mandatory solid waste diversion, each LGU plan must include an implementation
schedule outlining how the LGU will divert at least 25% of all solid waste from waste disposal
facilities through reuse, recycling, and composting initiatives as well as other resource recovery
activities within five years of the law's implementation.
There are many factors that increase the development of solid trash. These variables are
subject to regional variation and are impacted by social, economic, and cultural factors. Listed
below are some frequent reasons: (McAllister, 2015).
Rising industrial production
Solid waste output can definitely be significantly influenced by rising industrial production.
Industrial production entails the mass production and processing of items, which frequently results
in the creation of trash.
As an unavoidable result of their industrial processes, industries frequently produce
garbage. These leftover raw materials, packaging components, and byproducts or emissions from
chemical reactions or other industrial operations can all be included in this garbage.
Population growth and trash generation
The amount of garbage generated by people and communities also rises as the world's
population continues to rise.
Consumption has increased as a result of the growing population and the resulting
demand for products and services.
Urbanization
More individuals moving to cities and other densely populated places generally coincides
with population expansion. Due to their dense population, increased economic activity, and more
affluent consumer habits, urban regions typically produce more garbage.
Inadequate waste management systems
Inadequate collection, incorrect disposal, and a lack of facilities for recycling and
composting, can increase the amount of solid waste. This is especially common in resourceconstrained areas or developing nations.
Lack of knowledge and education
Rise in the production of solid waste may be caused by a lack of understanding of suitable
waste management techniques. Lack of knowledge about composting, recycling, and the effects
of garbage on the environment may lead to poor disposal practices.
In this study, solid wastes particularly the agricultural wastes are being investigated.
The foundation of the global economy, and a key factor in ensuring human survival, is
agriculture. (Plastic Exp, n.d.). Agricultural waste has, however, significantly increased along with
the growth in agricultural productivity. There is significant environmental degradation as a result
of the inappropriate treatment and disposal of organic waste and solid waste produced by
agricultural activities.
Solid wastes from crop production are primarily generated from agricultural activities that
involve crop production. Such agricultural solid wastes include things like crop leftovers and
husks. (Saleh, 2020).
Both organic and inorganic components are included in agricultural waste. In contrast to
inorganic trash, which includes plastic, chemical containers, and other items used in farming,
organic wastes include crop remnants, manure, and other plant and animal byproducts. The vast
amount of agricultural waste produced annually is a big reason for concern owing to the possible
harm it can do to the environment.
The nutritional value and appealing properties of biodegradable garbage are being
concentrated on to enable to produce various kinds of products that can be utilised.
Agricultural operations typically involve the preparation, production, storage, processing,
and consumption of agricultural products, livestock, and their byproducts, all of which generates
agricultural waste. (Saleh, 2020).
The primary cause of the production of agricultural solid waste is farming activities. Every
stage of farming activities, from clearing the land to harvesting the crops, produces agricultural
waste. Solid waste is produced during the entire process, from setting up the pen for the animals
to arrive at the farm to setting up the pasture or paddock until the animals are killed and sold.
Another way to produce a lot of agricultural solid waste is through a poor road system for
moving harvested goods from the farm to the market or storage. This occurs mostly as a result of
the poor road infrastructure in some developing nations, which could cause a traffic accident or
delay the transportation of agricultural products from farms to markets.
Solid garbage production is also a result of inadequate electricity or a lack of rural
electrification. The ability to store the harvested produce in the cold would have made it easier to
prevent spoiling, which would have reduced agricultural solid wastes.
One further significant source of agricultural solid wastes is food spoilage. An estimated
40% of food is lost or wasted every year in the US alone. The Natural Resources Defense Council
has predicted that this waste will cost around 162 billion dollars.
Solid waste from agriculture produced in the kitchen from family consumption is typically
the outcome of agricultural activity. Typically, there is some creation of agricultural solid waste
associated with family use of agricultural products. These wastes are created in some cases for
practical reasons. For instance, many families dump orange peels and banana peels as
agricultural solid wastes.
EFFECTS
Effects of poor solid waste management
Waste as in general is causing environmental pollution on earth surface, water, and
air. (Gond, 2020).
According to Goyol (2021), environmental impacts from poor waste management are
numerous. It hurts a nation's total economy in addition to having an unpleasant outcome. Animals
that depend on the environment, in addition to humans, are also affected by the harm. The
production and improper management of garbage pose a serious hazard to the air, water, and
land. There are numerous methods for managing garbage, including energy conservation,
recycling, biological processing, and burning. But our ineffective waste management still causes
problems.

For one thing, the smoke from burning is irritating to the eyes. It also induces difficulty in breathing.
When dumped along the roads, heaps of cornhusk become eye sores. These heaps of cornhusks
would be there for a long time as they decompose very slowly (Gerona, 2012; Ahmad et.al, 2015).
