Introduction
This research paper describes the state of the art of the research on
`Solid Waste Micro and Small Enterprises and Cooperatives in
Latin-America', carried out between January and May 1996. The countries
involved were: Bolivia, Brazil, Colombia, Costa Rica, El Salvador,
Guatemala and Peru (an inventory study was carried out in Paraguay). The
research was coordinated by ACEPESA (Asociación Centro Ejecutor de
Proyectos Economicos y de Salud) of Costa Rica, IPES (Instituto de
Promoción de la Economia Social (IPES) of Peru and WASTE. This research
project was made possible with funding from the Urban Waste Expertise
Programme (UWEP) of WASTE itself and from the Urban Management Programme
(UMP-LAC and UMP-WB). The present paper is a summary of earlier papers
presented at international conferences in Cairo and Istanbul (see
Literature). The Spanish edition of a book describing all experiences is
available; the English edition will be available in the beginning of
1998.
1 Justification and Objectives
The research had two prime objectives: firstly, to contribute to the
improvement of solid waste management services and secondly, to promote
adjustments to national, regional, local and sectorial policies to allow
for the improvement and setting up of micro enterprises and cooperatives
(PYME/COOP) working in this area in Latin America. To meet these
objectives, the research study proposed documenting and analysing the
experiences of small and micro-enterprises and cooperatives in
Latin-America, which have become important mechanisms in presenting
alternatives to the grave environmental problems generated by inadequate
solid waste management.
Since little is known of projects in Latin-America in English and
French speaking countries, it was assumed that the Latin American
examples would provide interesting experiences and lessons for Africa
and Asia.
2 Scope and Limitations
The different entrepreneurial forms studied are found in every part
of the waste cycle: some of them promote recovery at the point of
origin, others play an important role in the sweeping and cleaning of
public streets, in garbage collection and in the management of
small-scale final disposal sites. Recycling enterprises were not
included in the study. The number of enterprises from each country and
their year of origin are listed in the following table according to
their type of activity.
Special attention was paid to financial-economic aspects of the
enterprises and we have attempted to elaborate performance indicators
for each enterprise. However, in some cases it was difficult to obtain
financial information because no accounts were kept, nor was there a
register of the waste collected, separated or disposed of. This
situation restricted the possibility of drawing detailed comparisons.

3 Methodology and State of the Art
Methodological guidelines were elaborated and were discussed and
explained during a workshop in Costa Rica in February 1996. In May 1996,
a second workshop was held in Peru to present the studies and to draw
conclusions. Field studies were carried out by local consultants. The
results were presented at HABITAT-II in Istanbul (June 1996), at the
UMP-conference on small and micro enterprises in waste management in
Cairo (October 1996) and at a World Bank seminar (November 1996). Final
reports are available from all countries and a book is currently in
production.
4 Results of Field Studies
4.1 Types of Initiators
By examining the origin and principal characteristics of their
activities, four "types" of initiators were identified: small
entrepreneurs, informal recovery workers, Community Based Organizations,
and NGOs.
- Small entrepreneurs
This type is represented by examples taken
from the City of Guatemala, El Salvador and Costa Rica. They are
projects initiated by small entrepreneurs, and offer waste collection
services directly to the population with municipal approval.
- Informal recovery workers
In this type, the entrepreneurial
organization was set up on the initiative of the recovery workers
(waste pickers and itinerant waste buyers). These projects were
established to assure the permanence of their jobs and to improve
their working conditions. Cooperatives in Brazil and Colombia are
examples of this type of initiative. They often received support from
the churches.
- Community Based Organizations
These are organizations formed by
the community to respond to its own needs. Examples can be found in
Costa Rica, El Salvador and Guatemala. The PYME/COOPs that basically
respond to community interests usually have very limited relationships
with the municipalities.
- Non-Governmental Organizations
This type of initiative
comprises small and micro enterprises formed with the support of NGOs
that have close links with the communities and which generally work in
waste collection in low-income areas. Examples can be found in
Bolivia, Peru and Colombia.
All of these entrepreneurial forms are characterized by the intensive
use of manual labour (a large number of workers in proportion to the
capital invested), a factor which has permitted many PYME/COOPs to
emerge and profit in the real world of free competition without
depending on donations or international loans for financing.
4.2 Employment Generation
The survey researched 89 PYME/COOPs which together account for more
than 800 jobs. It must be stated that the PYME/COOPs studied represent
only a small number of the total of PYME/COOPs that exist in the
countries investigated. Some of the examples studied:
- in Guatemala, five out of more than 300 waste collection
enterprises were studied
- in Colombia, four cooperatives were included in the research,
while more than 100 cooperatives exist in the country, most of them
being organized in the National Association of Recyclers (ANR)
- in Peru, 19 enterprises were studied out of a total of more than
100 enterprises.
From the survey, it was evident that the actual number of jobs
created in waste management activities is much higher, totalling around
10.000 jobs (excluding individual waste pickers and recyclers).
Alternative employment opportunities have also been set up, such as
the cooperative `Recuperar' in Medellin (Colombia), which has found jobs
for its members in other sectors (e.g. the manufacturing industries).
4.2.1 Income Generation
In general, the wages of PYME/COOP workers are higher than the
statutory minimum wage (see Table 2). An analysis of wages per activity
in the countries investigated, with the exception of recovery and
separation in Costa Rica, showed that all of the PYME/COOP workers earn
higher than the minimum wage.

If
the salaries are analysed by activity, the garbage collection and
transport workers of Guatemala are the most well paid, since they
receive 3.03 times the minimum wage. With respect to the recovery and
separation workers, in relative terms (average salary/minimum wage) as
well as absolute terms, those in Brazil are the best paid because they
receive 2.46 times the minimum wage. Sweeping activities were only
compared in Guatemala and Peru; PYME/COOP workers receive the highest
salaries in Peru.
4.2.2 Gender
The functions carried out by women in waste management are closely
related to the way men and women divide their labour both inside and
outside the home. However, the research shows that traditional divisions
of labour can be changed.
- Street Sweeping and Cleaning
In Peru, the micro enterprises
studied are made up exclusively of women who live in the marginal
urban areas of Lima. Here it is evident that the street sweeping
PYME/COOPs prefer to contract women because they consider them to be
more efficient at this work than men. This decision is based on the
gender stereotype that because women clean the home, they feel
comfortable with this type of work, transferring their domestic
cleaning experience to the public arena.
- Primary and Secondary Waste Collection
The following table
shows the participation percentages of men and women in the study
sample of solid waste collection enterprises. It is especially
interesting to note the differences in women’s participation in this
type of activity in the PYME/COOP in the Central American countries
with those of women in Peru and Bolivia.

The participation of women in this type of activity in Central
America is minimal. In Peru and Bolivia, the participation of women is
much higher. One of the reasons for this difference is the influence of
the majority of the NGOs, who guided the formation processes of the
enterprises, including the selection of poor, unemployed women from the
marginal urban areas.
One of the results of the investigation in Peru indicates that women
remain in the enterprises longer whereas most of the men consider it to
be a temporary job. Many men prefer to leave the PYME/COOP immediately
on finding a job or occupation considered more prestigious than garbage
collection. Women, however, see this job as their only source of income
and therefore perform their work with more responsibility and
continuity.
The above-mentioned situation provides a degree of insight into why
the enterprises are predominantly owned and managed by women. The
majority of the active associates are women and almost 70% are informal
or formal leaders (managers). It should be pointed out that some of
these women had previously acted as leaders in community organizations,
a circumstance which in some cases allowed them to become leaders in the
enterprises.
The following table shows the participation of men and women in the
solid waste recovery activities of the PYME/COOPs studied.

In the cases of the cooperatives in Colombia and Brazil, it is
difficult to determine the percentages of participation due to the
permanent fluctuation of the number of workers in the cooperatives. By
way of example, in the PROSPERAR cooperative, in Manizales, Colombia,
men occupy 69% of the jobs, women 23% and children 8%. These numbers
give an idea of the situation.
The participation of female manual labour is greater in recovery
activities than it is in garbage collection, probably because the
classification work requires visual-motor abilities and prolonged
periods of concentration. Both abilities are traditionally associated
with women. Another condition which facilitates the incorporation of
women in this type of labour is the fact that the installations of the
enterprise where they carry out the classification is generally located
in a room in their own home. Thus they can attend both to their domestic
work and to the work of the micro-enterprise.
4.3 Financial Aspects
4.3.1 Costs of collection and street cleansing
Even when the income levels and the costs of all the PYME/COOP have
not been precisely determined, there are relevant factors which indicate
that these have a "basic" income which permits them to continue
operating and guarantees their future growth to some degree. In general
the enterprises make enormous efforts to attain the best possible
income. Because of this, all of them continuously seek to reduce their
costs and maximize their income.
In some cases, we have been able to calculate performance indicators:
costs per ton collected. As shown in Table 5 the average collection
costs of the PYME/COOP in Peru and Guatemala are lower than the average
for Latin-America.

Both indicators provide strong evidence for the cost-effectiveness of
the PYME/COOP.
4.3.2 Payment of services
It is important to point out that there is a basic difference in the
income obtained by those PYME/COOPs which charge the population directly
for their services and those which are paid by the municipalities. With
regard to the first type of enterprise, the results in the two countries
researched are completely different.
In Guatemala, there is a competitive market for waste collection and
transportation services, and the method of direct payment by the
residents is very effective. In several cases, this has enabled the
growth of the PYME/COOP. However, in Peru, where the municipality has
granted the PYME/COOP the right to charge the people directly for this
service in some areas, this method has had little success and
non-payment or delayed payment is a frequent result. This situation in
Peru is basically due to three factors:
(a) There is a non-payment culture or tradition for these services
because people consider that these services should be provided by the
government free of charge.
(b) The lack of concern of people for the
solid waste problem.
(c) In Peru, services are primarily provided to
low income areas, while in Guatemala services are generally provided to
middle and high income areas.
The customers are not the only bad payers. In some cases where the
PYME/COOPs have a contract with the municipality, payment may be delayed
by several months. This is particularly the case in Peru.
4.3.3 Hidden Costs
In order to be present in the market and to be able to compete, the
PYME/COOPs have had to implement "defence" mechanisms. One of these
mechanisms is that of hidden costs. This refers to those costs which,
although they should be paid by the PYME/COOP, are not. Consequently,
the enterprises do not consider these costs as part of their real costs.
This concept was introduced in the investigation with the object of
evaluating and understanding the logic of the micro-enterprises and
cooperatives and of understanding how they remain in the market and,
above all, how the participation of external agents in this type of
enterprise contributes to their existence in one way or another. The
survey showed that there are common hidden costs in all of the
PYME/COOPs. One of the most representative examples is the cost of
labour or personnel. The hidden cost of personnel includes the unpaid
labour of the family members of the owners of the PYME/COOP, and unpaid
legal social benefits for many staff such as medical insurance and old
age pensions.
4.3.4 Hidden benefits
The fact that not all the inhabitants are disposed to pay for the
service has also prompted many enterprises to interact with the
community through educational campaigns. This situation can be seen in
several countries (e.g. El Salvador, Peru, Bolivia).
The disrespect of the population for waste collectors has stimulated
cooperatives to engage in environmental education. The cooperatives in
Brazil and Colombia pay great attention to organising educational
campaigns aimed at encouraging awareness of the importance of recycling
among the population and stimulating the community to cooperate in
recovery activities. Since environmental education campaigns are carried
out cost free, they were identified as one of the most important hidden
benefits of the work of the PYME/COOP.
4.3.5 Financing of the PYME/COOP
The enterprises that arose `spontaneously', received loans from
friends, families and banks. In some cases, particularly those in which
NGOs played a crucial role in establishing the PYME/COOP, special credit
schemes were established to serve the needs of the enterprise.
We have not identified a single case that makes use of the micro
credit programmes of international agencies such as the World Bank or
the IDB. In Peru it was discovered that the existing micro credit
schemes do not extend loans to waste collection enterprises - firstly
because a service providing enterprise is not considered a viable
enterprise and secondly, because enterprises must operate for at least
one year before they are eligible for credit. In general, micro credit
programmes have insufficient knowledge of the operational logistics of
waste management enterprises.
4.4 Technology
4.4.1 Types and Ownership
The enterprises investigated use completely different technologies.
These vary from carts made from waste to trucks (see Appendix 1). In the
majority of the cases investigated the technology used is owned by the
PYME/COOPs themselves. They have acquired the equipment they use in
their work in different ways: by making it, through credits, or through
donations.
4.4.2 Technological adaptations
Distinct examples of technological adaptations exist. For example, in
Costa Rica, one enterprise (garbage collection) uses a truck with a
partition and chain for emptying the solid waste. ECOASEO (Colombia) has
a three-ton garbage truck, in which the compacting system has been
removed in order to facilitate the recovery of recyclable materials.
This vehicle has been designed, at the suggestion of the recycling
workers, by an engineer (a Social Foundation functionary) and assembled
by a national firm using local technology.
In the majority of garbage collection micro-enterprises investigated
in Peru, the equipment used was made with certain ergonomic
considerations in mind. This has been the case in the design of the
garbage collection tricycles and capachos (a fifty-gallon drum on wheels
with a handle for pushing). In some cases the micro-enterprise workers
have detected defects in the equipment and have introduced improvements
in order to make their work easier and quicker.
In spite of the adaptations made, there are still technological
aspects which need improvement. For example, the principal technical
problem with the carts in El Salvador is the bicycle wheels, which are
easily damaged by the weight of the refuse and the conditions of the
terrain. In most cases, these are small problems which increase the
operational costs of the enterprises.
4.4.3 Effectiveness versus efficiency
The techniques and technology used for the collection and
transportation of waste have been adapted to the situations within in
each locality and have largely been improvised. The collection method is
effective, but can at the same time be inefficient. This does not
reflect on the technology used, but rather on the enterprise’s poor
logistics.
Taking the garbage collection micro-enterprises of Guatemala as an
example, garbage collection can be said to be effective because, using
appropriate technology, 90 to 95% of the waste produced by the
population is collected and 60 to 70% of residents is willing to pay for
the service. However, the system established to collect this 90% is not
efficient. The clients are not concentrated in the same work area (a
collector works in at least three different zones), and the distance
between the work area and the workers’ homes is great (the worker must
travel at least half an hour to get to his work area). Moreover, in some
cases the unloading of waste at the final disposal sites is slow, thus
prolonging operation time.
4.5 Linkages with municipalities
4.5.1 The responsibility of municipalities
In all cases, municipal responsibility for solid waste encompasses
all of the corresponding services. However, solid waste management
occupies a position of prime importance on the municipal agenda only in
some cases. Only in Costa Rica, Colombia, Bolivia and Brazil does the
subject of solid waste receive political attention, although this does
not always guarantee adequate solid waste management. Recovery and
recycling are usually not seen as the responsibility of the
municipality.
4.5.2 Types of relationships
The relationships between the municipalities and the PYME/COOP are
very different in the countries investigated. On the one hand, in
Guatemala the relationship is distant because the municipality does not
intervene in any way in the functioning of the garbage collection
system. There the micro-enterprises decide for themselves who they will
provide their services to, how much they will charge their clients, when
they will attend them, and so forth. While in Peru, on the other hand,
the relationship is very close. The municipality determines in great
detail how the PYME/COOP must operate.
4.5.3 Contractual relations
In the majority of the cities investigated the micro-enterprises
operate under contract or concession from the municipality. This
contract varies from a period of four to six months as in Cucuta,
Colombia, to a period of several years. For example, in Costa Rica and
in Villa Nueva, Guatemala, some PYME/COOPs have managed to acquire
contracts for up to ten years. However, the majority of the contracts
with the enterprises are for an average of one year.
Despite this, there are examples where the PYME/COOPs operate without
written or verbal contracts, but have been granted authority to operate
by the municipality. In the City of Guatemala, more than 300
micro-enterprises have collected solid waste without any form of
contract for the last forty years. Likewise, there are examples such as
the city of El Alto, Bolivia, the district of Villa El Salvador in Lima,
Peru and the majority of the cities in Costa Rica where
micro-enterprises are in operation.
4.5.4 Dependency relationships
Even when there is no contract between the PYME/COOP and the
municipalities, a dependency relationship is sustained, especially with
regard to the authorization necessary for access to the final disposal
sites. These sites are almost always managed by the municipality, which
is the reason why the PYME/COOPs require municipal permission to dispose
of the solid waste collected. Another dependency relationship is the
coordination required of the garbage collection enterprises, which do
not directly transport the waste to the final point of disposal, and the
municipal vehicles which should carry out this task.
4.6 Community Participation
The PYME/COOPs that are dedicated to garbage collection and
transportation are those which establish closer relationships with the
communities as a result of the characteristics of their activity. In
this case the PYME/COOPs were created to meet the needs of the
community. They offer personalized service and form part of the
community. From the analysis it was concluded that the client's
satisfaction with the service offered is vital to the permanence of the
PYME/COOPs in the communities and is a necessary condition for their
success.
From the start of the activities, and especially during operation,
the communities participate in distinct ways:
- They put the waste out in time for collection and store it as
required by the enterprises.
- They participate in community cleaning tasks.
- They pay for the service.
- They control and supervise the work. For example, they control the
quality of the work, the running of the route according to the
schedule, the demeanor of the worker, the correct use of the uniform
and equipment, etc. They also comment on the service rendered, discuss
the operative problems, and make suggestions concerning how the
service can be improved.
- They participate in the management of the enterprise. For example,
a few enterprises in El Salvador, Costa Rica and Brazil are the
property of a community organization.
- They pressurise the municipal authorities into allowing the
PYME/COOP to offer the service. For example, one community pressurised
the municipality to retract its decision not to extend the
enterprise’s contract.
- They participate in the design of solid waste collection projects
to be presented to the municipality, in the convocation and selection
of workers, in the establishing of tariffs, etc.
4.7 Roles of Stakeholders
The research identified a large variety of stakeholders’ roles, a few
examples of which will be given here (see also Appendix 2). The simplest
system encountered is the system whereby the enterprise delivers the
services to the beneficiaries and the beneficiaries pay the enterprises
directly. The role of the municipality is very limited and often implies
no more than a certain type of authorization or tolerance. These systems
are often spontaneous initiatives, which emerged without external
support, and exist, for example, in Guatemala, Bolivia and Costa Rica.
The case of Guatemala City is interesting (see Figure 2). The role of
the municipality is almost absent, which makes this example one of total
privatization. 300 to 400 yellow trucks, as they are called locally,
provide waste collection services. The ‘technical support’ of the
municipality means no more than a quick inspection of the vehicle, after
which it receives a stamp. The non-profit sector (NGOs and CBOs) is
completely absent.
The system in Peru and Bolivia is quite different (see Figure 3). It
is important to note that most of the enterprises did not emerge
spontaneously, but were initiated by NGOs at the request of either the
community or the municipality. In this system the enterprise provides
the service, the beneficiaries pay taxes to the municipality and the
municipality contracts and pays the enterprise. The role of NGOs is very
strong: they provide financial, technical and institutional advice and
manage to obtain small loans from the banks. The system in La Paz,
Bolivia, is basically the same as the Peruvian system. The differences
are that the municipality of La Paz provides the loans and that a law
was recently established to facilitate the participation of citizens
through locally established Committees of Vigilance, which have a role
in the monitoring and control of the enterprise. If the enterprise does
not deliver an adequate service, these committees can complain, which
may result in terminating the contract.
In Costa Rica, the situation is again quite different (see Figure 4).
The enterprises studied operate in semi-urban areas, where the role of
the municipality is often limited. Most of them also emerged
spontaneously, in tourist areas in particular. In Costa Rica, CBOs are
established by law and receive state financing, which they can spend
according to their own needs and priorities. One system encountered is
the ‘communal enterprise’, whereby the beneficiaries pay fees to the CBO
and whereby the CBO employs workers to provide the service. Waste
collection is only one of the activities of the CBO. Another system
consists of beneficiaries paying the fees directly to the enterprises.
These enterprises often receive payment from both the beneficiaries (the
households) and the state.
5 Conclusions and Recommendations
It is difficult to draw specific conclusions from such a diversity of
activities and experiences encountered in seven countries. However, the
two most important general conclusions are presented below:
- The PYME/COOPs studied and described, can contribute to solving
the problems of urban waste management, directly tackling the main
causes which generate them:
- by introducing efficiency in waste management through the
transfer of services to the PYME/COOP;
- by reducing investment costs and operating costs involved in
waste management by using unconventional systems characterized by
the use of simple technologies and the intensive use of labour; and
- by achieving the active participation of the population in the
solution to environmental problems by seeking to raise their level
of awareness of environmental health.
- One of the major constraints the investigated enterprises face is
the limited institutional framework in which they operate. In
particular, the municipalities face serious problems with, for
example, staff incompetence, inadequate legislative and regulatory
infrastructure and inadequate administrative and financial systems. In
this context, they can hardly comply with their normative, regulatory
and fiscal functions, which are indispensable if enterprises are to
provide the services in an adequate and integrated way.
Intervention programmes need to be directed at the three principle
actors involved in waste management:
- municipalities and other government agencies: training in
principles of integrated sustainable waste management, regulation and
control of privatized services, taxation;
- small and micro enterprises and cooperatives: training in
negotiating capacities, bookkeeping, working conditions, business
management and
- the population: environmental education, strengthening of
Community Based Organizations.
6 Proposed Follow-Up Activities
The following activities have been proposed:
- Execution of the project: `Urban Environmental Management of Solid
Waste’ in La Ceiba
- Development of training manual
- Development of performance indicators
- Formulation of `Programme of Technical Assistance for
microenterprises and municipalities in Latin-America
