Waste management and reuse of landfill

Published

on

‘Locked down’ due to Covid-19 and going through some of my old collections, I came across an interesting publication as titled above. As this subject is relevant today, concerning climate change and renewable sources of energy, I quote the 11 suggestions made in the introduction, for the information of the authorities interested.

1. Total landfill management concept – With available space for landfills declining daily and concerns over population and dwindling natural resources; a Total Landfill Management Concept covering handling, recycling, composting, extraction and use of gases and maintenance and re-use of sanitary landfills is becoming vital.

2. Landfill gas – Anaerobic decomposition of organic solid waste in the landfill environment produces landfill gas [LFG]. LFG mainly consists of methane and carbon dioxide, both of which are odorless, Trace concentrations of other volatiles, often maladdress or toxic gases, are also found in LFG. LFG can migrate through soil into structures located on or near landfills. Since methane presents a fire or explosive threat, LFG must be controlled to protect property, and public health and safety. Also, many jurisdictions require landfill owners/operators to reduce reactive organic gas emissions to improve regional air quality, Thus, engineered solutions are needed to efficiently and safely monitor, collect, and process landfill gas.

3. Solid waste management planning – As existing landfills near capacity, as less land becomes available for the siting of new municipal solid waste [MSW] landfills, and regulatory agencies adopt stricter rules on waste disposal, or jurisdictions are facing the need to have a solid waste management plan. Unlike plans in the past, these plans are focusing on more than just collection and disposal of MSW, such as recycling, resources recovery, waste-to-energy and incineration, and examine other methods for reducing waste at the beginning of the cycle – i.e. less packaging, requiring biodegradable wrappings [bottle bills etc.

4. Waste composition studies – Waste composition studies are performed for a number of reasons, one of which is the most common – as a start towards recycling programs. Waste composition studies can assist solid waste management departments

5. Recycling – With available space in landfills declining daily, and concerns over population and dwindling natural resources growing, many communities are looking for recycling as one way to ease the strain created by increasing solid waste. Assisting communities in determining the most economically feasible and efficient method of handling recyclable materials. Several steps are involved in determining what recyclables exist in the waste stream. Evaluating the market to discover what are the current and projected needs for recyclables, comprehensive planning so implementation of a recycling plan goes smoothly and fits in with the overall goals of the community, and siting design of the recycling facility.

6. Material Recovery Facilities [MRFs] – Material recovery facilities, also sometimes called separation facilities, can be multi-million dollar installations with sophisticated, automated sorting, baling, crushing , wash-down machines or an empty building renovated with a conveyor and magnetic separator. The size and types of equipment of a MRF is determined by the usage – is the facility only used by the residents of a town, by a large city or country, or is it regional?. Much of what a MRF accepts is dictated by supply and demand and recycler’s requirements. One of the keys for designing a MRF is to design the flexibility as the demand for different types of recyclable grows.

7. Patented Technology for Conversion of Non-Organic Waste [Plastics etc] into Composite Structural Material – This process uses polypropylene, plastic and similar waste materials combined with chain fibers from biomass [wood, straw etc] to produce lightweight composites, which can be used for earth filling, building construction etc. The chemical and mechanical action of the process leads to steam explosion of the biomass material, through exposing more surface area to the melting polymers which promotes entanglement and adhesion. This allows for use of 65% biomass, 25% polypropylene,1 to 2% Epolene and 2 to 3% fly ash. Together, these longer chain fibers create an improved matrix with more flexibility at lower costs due to the wide variety of biomass which may be used. By using more fiber and less polymers, a lighter weight composite results and particle size is larger due to the chain fibers. Where waterproofing and external use are the prime concerns or where Maximum strength is desired, more plastic and finer particles can be incorporated. Color can be added to assimilate natural woods such as redwood or yellow pine.

8. Transfer Stations – The siting, design and permitting of a transfer station, or a network of transfer stations in densely populated areas, can be difficult. Emotionally-charged issue for a community. Environmental , financial, legal, noise, traffic, aesthetics, public resistance, and health and safety concerns are some of the issues that must be dealt with when siting and designing a transfer station. Other considerations include hauling distances, collection vehicle arrival times and discharges rates, the needed tipping floor and loading area, etc. As the transfer station is one component in a solid waste management program, other vehicles, such as combining a waste transfer station with a recycling/or resource recovery facility must be taken into account.

9. Composting- Composting is becoming an important part of the recycling programme. Communities are finding it a useful tool to both keep yard waste out of the land fill, and to promote natural, and economic fertilisation of vegetable and flower gardens in urban and suburban areas. A plant of the solid waste management plan being conducted, strategy. The USEPA has conducted studies to determine if different types of composts [yard wastes, sewage, sludge, water waste sludge, food waste] can be processed for land cultivation and land reclamation purposes

10. Landfill Engineering – Landfill engineering assignments typically involve many elements, including – Siting of new landfills, – Geological and hydrogeological investigations. Environmental studies [ecology. Wetland, etc], Concept designs – Design [including leachate and landfill gas migration control and cap and cover plans]; – Operation plan – Preparation of permitting application packages and negotiations with regulatory officials. Environmental impact assessments and preparation of environmental impact reports. Closure and post-closure plans and Remedial action investigations and design.

11. Landfill Gas -Landfill gas [LFG] migration investigations, control and recovery design and continuing monitoring is absolutely necessary.

Labour exploitation at Sri Lankan audit firms: A regulatory blind spot

Published

on

A recent tragedy of a young audit professional has prompted a nationwide conversation on Sri Lanka’s audit work culture. What was initially described as an untimely passing has since raised serious concerns about excessive workloads, workplace responsibility, and the well-being implications of the professional pressure. Accordingly, this article seeks to explore prevailing audit culture and professional practices in Sri Lanka, and highlights areas where thoughtful reform may be considered

The Evolution of Accounting and Finance Education in Sri Lanka

Over the past several decades, accounting and finance education in Sri Lanka has evolved from a narrowly technical field into a recognised professional discipline. Universities and professional institutions now offer specialised programmes aligned with international standards, covering accounting, finance, auditing, taxation, and corporate governance.

Professional bodies have modernised curricula by incorporating international accounting and auditing standards, ethics, and governance related content. As a result, Sri Lankan accounting graduates develop both technical competence and professional judgment, enabling them to compete successfully in multinational corporations, international audit networks, and global financial institutions, both locally and overseas.

This progress reflects a broader national commitment to professional excellence. Accounting and finance are now recognised as disciplines central to economic governance, market transparency, investor confidence, and public trust.

Why Professional Qualifications Matter

Professional qualifications often act as gateways to the corporate world. Professional pathways in Sri Lanka include qualifications offered by the Institute of Chartered Accountants of Sri Lanka (ICASL), the Association of Chartered Certified Accountants (ACCA), the Chartered Institute of Management Accountants (CIMA), the Institute of Chartered Professional Managers (ICPM), and the Association of Accounting Technicians (AAT).

For employers, these qualifications signal technical competence, ethical compliance, and completion of structured practical training. For students, they represent professional legitimacy, career security, and upward mobility.

Therefore, families and students invest significant time and resources in this pathway, reflecting its importance, often exceeding the practical value of a degree alone. Qualified professionals trained through this system contribute to both Sri Lanka’s domestic financial sector and overseas markets.

The Growth and Public Role of the Audit Sector

Alongside educational development, Sri Lanka’s audit sector has expanded in scale and influence as businesses have become more complex and globally connected. Audit firms now operate across the listed companies.

Audit firms perform an important public interest function by assuring the credibility of financial information, supporting investor confidence, and underpinning regulatory compliance and corporate governance. Beyond service delivery, they also act as professional institutions that determine norms and train future leaders in accounting and finance.

As a result, internal practices within audit firms, including organisational culture, workload expectations, remuneration, and supervision, have implications that extend beyond individual workplaces, influencing professional judgment, audit quality, and long-term public trust.

The Dream of Becoming a Chartered Accountant

For thousands of young Sri Lankans, becoming a Chartered Accountant represents one of the most respected professional ambitions. It is widely viewed as a symbol of discipline, resilience, and upward mobility. Students enter the pathway with the expectation that years of study, sacrifice, and perseverance will ultimately lead to professional recognition and stability.

A defining feature of this pathway is mandatory practical training. To qualify, students must complete a prescribed period of supervised training, most commonly within audit firms. This requirement is designed to bridge theory and practice, ensuring that academic knowledge is reinforced through real world exposure, professional supervision, and ethical decision making.

In practice, securing a training position is often the most decisive and competitive stage of the journey. Without completing this training, the qualification remains unattainable regardless of examination success. Therefore, audit firms are not only employers but also essential gatekeepers to professional advancement, controlling access to qualifications, experience, and future career opportunities.

Where the System Begins to Strain

This structure, while well intentioned, creates a significant imbalance of power. Trainees depend on audit firms not only for income, but also for the completion of their professional qualification. In such circumstances, questioning workloads, working hours, or basic welfare provisions can feel risky. Many trainees remain silent, fearing that concerns could delay qualification or affect future career prospects.

Audit work is demanding worldwide, particularly during peak reporting periods. Long hours, tight deadlines, and intense fieldwork are widely recognised features of the profession. However, the concern arises when these pressures become normalised without sufficient regard for rest, safety, remuneration, or minimum working conditions.

Training allowances and entry-level remuneration in audit firms are often modest relative to workloads and expectations, with trainee allowances typically ranging from LKR 10,000 to 20,000 per month, despite daily working hours that frequently extend 8 to 12 hours. Many trainees accept low pay and long hours as temporary sacrifices in pursuit of long-term professional goals. Over time, when such conditions are justified as “part of training,” unhealthy practices risk becoming normalised and embedded within professional culture.

Such environments may still produce technically competent professionals, but at the cost of burnout, ethical fatigue, and reduced long term engagement with the profession.

A Regulatory Blind Spot

In Sri Lanka, audit firms are regulated by CA Sri Lanka with respect to professional standards, ethical conduct, examinations, and prescribed training requirements, thereby playing an important role in maintaining the profession’s credibility and international standing. This is a professional regulation.

However, professional regulation serves a different purpose from organisational or workplace oversight. While audit firms are subject to general labour laws, there is no audit specific public oversight mechanism that systematically reviews audit firms’ internal governance, remuneration structures, or training environments.

This creates a regulatory asymmetry. Audit firms scrutinise others under detailed regulatory frameworks, yet their own internal systems are not subject to equivalent public review. Given the large population of trainees with limited bargaining power, this gap may affect professional sustainability, audit quality, and public trust.

Following a recent tragedy involving a trainee, CA Sri Lanka issued a public condolence statement acknowledging stakeholder concerns and confirming that the circumstances are under review.

Looking Ahead

To strengthen the long-term sustainability of the audit profession, Sri Lanka may consider the following measures:

* Establish a dedicated public oversight body for audit firms, with responsibility for monitoring firm level governance, training environments, and organisational practices, complementing existing professional regulation.

* Introduce transparency reports for audit firms, requiring disclosure of governance structures, quality control systems, training arrangements, and continuing professional education practices.

* Apply modern labour governance principles, drawing on modern slavery frameworks used internationally that emphasise prevention, transparency, and early identification of labour related risks.

* Improve visibility of trainee remuneration and workload practices, particularly where mandatory training creates structural dependency.

* Strengthen coordination between professional self-regulation and public oversight, ensuring that professional excellence is supported by sustainable and accountable organisational environments.

These measures do not imply illegality or misconduct. Rather, they reflect an opportunity to align Sri Lanka’s audit profession with evolving global norms that prioritise transparency, dignity, and long-term public confidence. If audit firms are entrusted with holding others accountable, the systems governing them must also reflect responsibility toward the people who sustain the profession.

Buddhist insights into the extended mind thesis – Some observations

Published

on

It is both an honour and a pleasure to address you on this occasion as we gather to celebrate International Philosophy Day. Established by UNESCO and supported by the United Nations, this day serves as a global reminder that philosophy is not merely an academic discipline confined to universities or scholarly journals. It is, rather, a critical human practice—one that enables societies to reflect upon themselves, to question inherited assumptions, and to navigate periods of intellectual, technological, and moral transformation.

In moments of rapid change, philosophy performs a particularly vital role. It slows us down. It invites us to ask not only how things work, but what they mean, why they matter, and how we ought to live. I therefore wish to begin by expressing my appreciation to UNESCO, the United Nations, and the organisers of this year’s programme for sustaining this tradition and for selecting a theme that invites sustained reflection on mind, consciousness, and human agency.

We inhabit a world increasingly shaped by artificial intelligence, neuroscience, cognitive science, and digital technologies. These developments are not neutral. They reshape how we think, how we communicate, how we remember, and even how we imagine ourselves. As machines simulate cognitive functions once thought uniquely human, we are compelled to ask foundational philosophical questions anew:

What is the mind? Where does thinking occur? Is cognition something enclosed within the brain, or does it arise through our bodily engagement with the world? And what does it mean to be an ethical and responsible agent in a technologically extended environment?

Sri Lanka’s Philosophical Inheritance

On a day such as this, it is especially appropriate to recall that Sri Lanka possesses a long and distinguished tradition of philosophical reflection. From early Buddhist scholasticism to modern comparative philosophy, Sri Lankan thinkers have consistently engaged questions concerning knowledge, consciousness, suffering, agency, and liberation.

Within this modern intellectual history, the University of Peradeniya occupies a unique place. It has served as a centre where Buddhist philosophy, Western thought, psychology, and logic have met in creative dialogue. Scholars such as T. R. V. Murti, K. N. Jayatilleke, Padmasiri de Silva, R. D. Gunaratne, and Sarathchandra did not merely interpret Buddhist texts; they brought them into conversation with global philosophy, thereby enriching both traditions.

It is within this intellectual lineage—and with deep respect for it—that I offer the reflections that follow.

Setting the Philosophical Problem

My topic today is “Embodied Cognition and Viññāṇasota: Buddhist Insights on the Extended Mind Thesis – Some Observations.” This is not a purely historical inquiry. It is an attempt to bring Buddhist philosophy into dialogue with some of the most pressing debates in contemporary philosophy of mind and cognitive science.

At the centre of these debates lies a deceptively simple question: Where is the mind?

For much of modern philosophy, the dominant answer was clear: the mind resides inside the head. Thinking was understood as an internal process, private and hidden, occurring within the boundaries of the skull. The body was often treated as a mere vessel, and the world as an external stage upon which cognition operated.

However, this picture has increasingly come under pressure.

The Extended Mind Thesis and the 4E Turn

One of the most influential challenges to this internalist model is the Extended Mind Thesis, proposed by Andy Clark and David Chalmers. Their argument is provocative but deceptively simple: if an external tool performs the same functional role as a cognitive process inside the brain, then it should be considered part of the mind itself.

From this insight emerges the now well-known 4E framework, according to which cognition is:

Embodied – shaped by the structure and capacities of the body

Embedded – situated within physical, social, and cultural environments

Enactive – constituted through action and interaction

Extended – distributed across tools, artefacts, and practices

This framework invites us to rethink the mind not as a thing, but as an activity—something we do, rather than something we have.

Earlier Western Challenges to Internalism

It is important to note that this critique of the “mind in the head” model did not begin with cognitive science. It has deep philosophical roots.

Ludwig Wittgenstein

famously warned philosophers against imagining thought as something occurring in a hidden inner space. Such metaphors, he suggested, mystify rather than clarify our understanding of mind.

Similarly, Franz Brentano’s notion of intentionality—his claim that all mental states are about something—shifted attention away from inner substances toward relational processes. This insight shaped Husserl’s phenomenology, where consciousness is always world-directed, and Freud’s psychoanalysis, where mental life is dynamic, conflicted, and socially embedded.

Together, these thinkers prepared the conceptual ground for a more process-oriented, relational understanding of mind.

Varela and the Enactive Turn

A decisive moment in this shift came with Francisco J. Varela, whose work on enactivism challenged computational models of mind. For Varela, cognition is not the passive representation of a pre-given world, but the active bringing forth of meaning through embodied engagement.

Cognition, on this view, arises from the dynamic coupling of organism and environment. Importantly, Varela explicitly acknowledged his intellectual debt to Buddhist philosophy, particularly its insights into impermanence, non-self, and dependent origination.

Buddhist Philosophy and the Minding Process

Buddhist thought offers a remarkably sophisticated account of mind—one that is non-substantialist, relational, and processual. Across its diverse traditions, we find a consistent emphasis on mind as dependently arisen, embodied through the six sense bases, and shaped by intention and contact.

Crucially, Buddhism does not speak of a static “mind-entity”. Instead, it employs metaphors of streams, flows, and continuities, suggesting a dynamic process unfolding in relation to conditions.

Key Buddhist Concepts for Contemporary Dialogue

Let me now highlight several Buddhist concepts that are particularly relevant to contemporary discussions of embodied and extended cognition.

The notion of prapañca, as elaborated by Bhikkhu Ñāṇananda, captures the mind’s tendency toward conceptual proliferation. Through naming, interpretation, and narrative construction, the mind extends itself, creating entire experiential worlds. This is not merely a linguistic process; it is an existential one.

The Abhidhamma concept of viññāṇasota, the stream of consciousness, rejects the idea of an inner mental core. Consciousness arises and ceases moment by moment, dependent on conditions—much like a river that has no fixed identity apart from its flow.

The Yogācāra doctrine of ālayaviññāṇa adds a further dimension, recognising deep-seated dispositions, habits, and affective tendencies accumulated through experience. This anticipates modern discussions of implicit cognition, embodied memory, and learned behaviour.

Finally, the Buddhist distinction between mindful and unmindful cognition reveals a layered model of mental life—one that resonates strongly with contemporary dual-process theories.

A Buddhist Cognitive Ecology

Taken together, these insights point toward a Buddhist cognitive ecology in which mind is not an inner object but a relational activity unfolding across body, world, history, and practice.

As the Buddha famously observed, “In this fathom-long body, with its perceptions and thoughts, I declare there is the world.” This is perhaps one of the earliest and most profound articulations of an embodied, enacted, and extended conception of mind.

Conclusion

The Extended Mind Thesis challenges the idea that the mind is confined within the skull. Buddhist philosophy goes further. It invites us to reconsider whether the mind was ever “inside” to begin with.

In an age shaped by artificial intelligence, cognitive technologies, and digital environments, this question is not merely theoretical. It is ethically urgent. How we understand mind shapes how we design technologies, structure societies, and conceive human responsibility.

Buddhist philosophy offers not only conceptual clarity but also ethical guidance—reminding us that cognition is inseparable from suffering, intention, and liberation.

We do not want to be press-ganged 

Published

on

Reference ,the Indian High Commissioner’s recent comments ( The Island, 9th Jan. ) on strong India-Sri Lanka relationship and the assistance granted on recovering from the financial collapse of Sri Lanka and yet again for cyclone recovery., Sri Lankans should express their  thanks to India for standing up as a friendly neighbour.

On the Defence Cooperation agreement, the Indian High Commissioner’s assertion was that there was nothing beyond that which had been included in the text. But, dear High Commissioner, we Sri Lankans have burnt our fingers when we signed agreements with the European nations who invaded our country; they took our leaders around the Mulberry bush and made our nation pay a very high price by controlling our destiny for hundreds of years. When the Opposition parties in the Parliament requested the Sri Lankan government to reveal the contents of the Defence agreements signed with India as per the prevalent common practice, the government’s strange response was  that India did not want them disclosed.

Even the terms of the one-sided infamous Indo-Sri Lanka agreement, signed in 1987, were disclosed to the public.

Mr. High Commissioner, we are not satisfied with your reply as we are weak, economically, and unable to clearly understand your “India’s Neighbourhood First and  Mahasagar policies” . We need the details of the defence agreements signed with our government, early.
