Opis:
Cel – Podstawowym celem opracowania jest przedstawienie problemu marnotrawstwa żywności jako rzeczywistego i istotnego problemu, który nie został dotąd rozwiązany przez instytucje międzynarodowe i krajowe. Najbardziej istotny wydaje się problem braku ujednoliconej i dokładnej metodyki mierzenia tego zjawiska na poziomie krajowym, która jest niezbędna w celu podjęcia odpowiednich kroków przeciwdziałających marnotrawstwu żywności. Metoda badań – Artykuł stanowi przegląd obecnego stanu wiedzy i dostępnych statystyk opisujących skalę marnotrawstwa żywności. Na wstępie marnotrawstwo żywności zostało zdefiniowane w oparciu o międzynarodowe porozumienia, dokumenty i badania. Następnie, na podstawie różnych opracowań i źródeł danych, przytoczono szacunkowe wielkości marnowanej żywności w skali światowej oraz w krajach Unii Europejskiej. Wnioski – Przeprowadzona analiza dostępnych materiałów przekonuje, że marnotrawstwo na świecie jest ogromne oraz zróżnicowane zarówno geograficznie, jak i w zależności od etapu życia produktu żywnościowego. Implikacje /rekomendacje – Artykuł implikuje konieczność podjęcia prac nad ujednoliceniem klasyfikacji i metodyki gromadzenia reprezentatywnych danych. Takie działania powinny stanowić priorytet dla organizacji biorących udział w debacie na temat problemu marnotrawstwa żywności.
Purpose – The main objective of the study is to present the problem of food waste as a real and significant problem, which has not been adequately addressed by international and national institutions. The most important issue seems to be the lack of a well defined and accurate methodology to measure this phenomenon at the national level, which is necessary to take appropriate steps to counteract the problem of food waste. Research method – The paper provides an overview of the current state of knowledge and available statistics describing the scale of food waste. At the beginning, food waste is defined on the basis of international agreements, documents and research. Next, on the basis of various studies and data sources, the estimated amounts of food waste on a global and European scales are quoted. Results – The analysis of available statistics proves that food waste around the world is enormous and varied depending on a geographical region and on the stage of the life cycle of the food product. Implications/recommendations – The paper implies that harmonizing the classification and methodology of gathering representative data is necessary. Such work should be a priority for organizations participating in the debate on the issue of food waste.

Opis:
This comprehensive review explores the underutilized buckwheat hulls, sprouts, and grain and sprout extracts, concentrating on their nutritional characteristics, health advantages, and possible uses in developing functional food products. Buckwheat, a pseudocereal, is emphasized for its impressive nutritional content, including high levels of dietary fiber, essential minerals, and vitamins, as well as bioactive compound content, such as phenolic acids and flavonoids mainly rutin. The paper discusses the significant antioxidant and antimicrobial properties of buckwheat hulls, sprouts, and extracts, which contribute to their utility in creating healthier, functional food products. Buckwheat sprouts are noted for their enhanced levels of antioxidants and nutrients compared to mature grains. Meanwhile, buckwheat hulls, traditionally seen as by-products, are identified as sources of dietary fiber and flavonoids, suitable for use in dietary supplements and functional foods. The extracts from these parts are rich in bioactive compounds that offer health-promoting effects. The possible effects of addition of buckwheat hulls, sprouts, and extracts to food products in terms of nutritional, textural, and sensory properties are also discussed. The review underscores the need for further research to optimize the use of buckwheat less-utilized parts and to better understand their health impacts. By highlighting the novel uses and health benefits of buckwheat hulls, sprouts, and extracts, the review contributes to the growing field of sustainable food practices and the development of functional foods.

Opis:
The food industry produces large amounts of solid and also liquid wastes. Different waste materials and their mixtures were pyrolysed in the laboratory pyrolysis unit to a final temperature of 800°C with a 10 minute delay at the final temperature. After the pyrolysis process of the selected wastes a mass balance of the resulting products, off-line analysis of the pyrolysis gas and evaluation of solid and liquid products were carried out. The highest concentration of methane, hydrogen and carbon monoxide were analyzed during the 4th gas sampling at a temperature of approx. 720–780°C. The concentration of hydrogen was measured in the range from 22 to 40 vol.%. The resulting iodine numbers of samples CHFO, DS, DSFW reach values that indicate the possibility of using them to produce the so-called “disposable sorbents” in wastewater treatment. The WC condensate can be directed to further processing and upgrading for energy use.

Opis:
The purpose of the research is to investigate consumers’ perception concerning food wastage and their awareness of economic, social and environmental costs concerning the issue. The research focused on the concept of food waste in context of consumers’ attitude regarding this problem. Comparative analysis, synthesis and evaluation of scientific literature and legal documents, statistical data collection and analysis was performed together with the results of on-line survey of 500 households representing 1494 inhabitants from all Lithuanian counties. Data was analysed using statistical package for the social sciences (SPSS): descriptive statistics, frequencies, crosstabs. Lithuanians discard relatively small amounts of wholesome edible food in comparison with averages for EU 27, but most of them have the limited knowledge of the meaning of “best-before” dates, consumers are strongly influenced by retail promotions, and wasting food for them is primarily associated with a waste of money. State waste management policy is focused on waste sorting, while this research provides the evidence that households are insufficiently informed about economic, social and environmental costs concerning food waste. This underlines the necessity to review the current state policy with emphasis on public education as an important factor in minimizing household food waste. Lithuanians recognize that the consumers are mostly responsible for food waste, but food wasting is treated mainly as financial lost. The added value of this article is the proposal to create information campaigns that will cause a sense of guilt for food squandering.

Opis:
More than 30% of the world’s food production is wasted. Organic waste and residues are produced in a variety of sectors, including agriculture, food industry and forestry. Residues and waste are generated throughout the entire food production and use cycle: surplus food production, processing and distribution, and consumption. Some food that has not been consumed should be managed. Bioconversion using insects provides the opportunity to produce feed and energy using by-products of the agro-food industry. The aim of the work was to present the concept of “IN OIL: an innovative method for the bioconversion of by-products from food processing industry” under the project LIDER VII (co-financed by the National Centre for Research and Development). Project IN OIL is being implemented at the Poznań University of Life Sciences. IN-OIL’s main assumption is combining two ideas – waste into energy and waste into feed. The developed method will reduce the adverse impact of unused food on the environment by using ReFood products in insect feeding (Hermetia illucens). H. illucens (Black Soldier Fly) is a Diptera characterized by a very high index of growth, and rich source of fats and proteins. The main assumption of the project is based on the introduction of by-products from the food processing industry to feeding with larvae of H. illucens. Biomass of insect larvae will then be processed into products that will be used for feed and energy purposes.

Opis:
Food waste has recently received attention due to its environmental, economic and social impacts. Final processing of food waste encounters a number of technical challenges, arising from weak physical structure of food waste with weak porosity, high content of water, and low carbon-to-nitrogen relation. This study deals with the research of food waste processing in households by using an automatic device. The main objective of the study was to assess the toxicity of the end-product produced by an automatic device. The research included 10 experiments. The input foundation consisted of common food waste generated in household kitchens. Following its processing, the end-product was tested in a pot experiment for the germination capacity and biomass increase in different concentrations. The end-product was mixed with the reference soil in concentrations 5/95, 30/70, 50/50 (tested/reference substrate). The testing included three different plant species, i.e. Sinapis alba L., Hordeum vulgare L. and Cannabis sativa L. The germination capacity of plants and their increase in biomass were evaluated after 21 days. The increase in biomass was monitored by using the Before-After-Control-Impact method. The plants developed much better without the end-product additive to the soil substrate than with its small addition. The best germination capacity in the case of end-product addition was observed in the concentration ratio 30/70 in all plants. In spite of this, the highest increase in biomass was recorded in the concentration ratio 5/95. This might have caused the occurrence of mould in the pots. The test shows that the end-product made of food waste is toxic to plants; therefore, it is not recommended for direct application as a soil amendment.

Opis:
In this study, the effect of thermal pre-treatment (TP) on the physical characteristics and co-digestion of a mixture of food waste and sludge was investigated. The food waste (FW) to sewage sludge (SS) ratio used in this research is 1:2 (VS-based) to form a final concentration of 11.20%. The inoculum to substrate ratio was set at 1:1 (volumebased). Undoubtedly, the results show that TP has changed the physical characteristics of the food waste to sewage sludge mixture. The results show that the pretreatment increased the biogas production from 4385 ml for the untreated reactor to 5685 for the reactor R2(140) at 140 °C and the improvement in biogas production reaches 29.65% in the reactor R2(140) and the removal of volatile solids was 58.90%. Therefore, after the biomethane potential test, the temperature of 140 °C was found to be optimal in the production of biogas. The optimal condition is to use a mixture of pre-treated SS at the temperature of 140 °C and untreated FW, so TP is recommended to be used in anaerobic digestion of the mixture of food waste and sewage sludge.

Opis:
In modern agricultural biogas plants, the biowastes are being increasingly used for the biogas production. The food waste is also widely used in larvae breeding. This is an important because, based on biowaste, its proper management and green energy production is possible. This study aims to determine the biogas and methane efficiency of the Hermetia illucens larvae that were fed using the food waste. In the research on the biogas and methane efficiency, the Hermetia illucens larvae were used. The total solids (TS) of the substrate equals 30.35%, and the volatile solids (VS) content was 92.31% of TS. The larvae were fed only with the food waste of plant origin. The obtained substrates were homogeneous. The experiment was carried out under mesophilic anaerobic digestion conditions – 39°C in the 21-chamber biofermentor set in the Institute of Biosystems Engineering in Poznań University of Life Sciences. The anaerobic digestion process in the batch reactor ran correctly. Fermentation inhibition was not detected. The biogas efficiency for larvae amounted to 198.75 m3∙Mg-1 fresh mass (FM). On the other hand,the methane efficiency, amounted to 127.73 m3∙Mg-1, at the methane concentration of 64.27%. On the basis of the research, it was found that the larvae feeding on food waste can be used directly as anaerobic digestion in the bioconversion process.

Opis:
Anaerobic digestion of food waste is an encouraging technology for biogas production. Pretreatment of the substrate is needed to increase biodegradation. This study aimed to investigate the effect of alkali pretreatment and organic solvent pretreatment on biogas production. Physical pretreatment was also applied in this study. NaOH (0%, 2%, 4% and 6%) was used as alkali pretreatment. Ethanol (0, 2, 4 and 6%) was used as organic solvent pretreatment. The experiment was conducted in a 1 L batch digester under room temperature. Results showed that 0% NaOH generated the highest cumulative biogas yield of 46.1 mL/gVS. The best biodegradability of 37.5% was achieved in NaOH of 0%. The lower concentration of ethanol generated a higher biogas yield. The greatest cumulative yield of 41.5 mL/gVS was obtained at an ethanol concentration of 0% with a biodegradability of 33.84%. Statistical analysis proved that alkali pretreatment and organic solvent pretreatment had no significant effect on biogas production (p>0.05). Physical pretreatment had a significant effect (p<0.05) with the highest cumulative yield of 58.2 mL/gVS. The kinetic model proved that the modified Gompertz was a suitable model for predicting and simulating the kinetics of anaerobic digestion from food waste (R2 > 0.9).

The study analyses tax law regulations in force in Poland and in selected European Union countries which may influence attitudes of entrepreneurs (taxpayers) in taking actions aimed at preventing food waste. This analysis demonstrates that all countries investigated in this study have made attempts to develop and implement various measures to combat the problem of food waste. At the same time, it is worth noting that properly constructed tax preferences are an important factor in preventing food waste, which is part of the sustainable development strategy implemented by European Union countries. In this respect, actions must be long-term and they should be based on various legal measures. Further changes in this area will be determined by some key factors. These include the need to use tax law regulations or to determine economic and social trends. Directions of activities of the state, local government and non-governmental organizations for counteracting food waste will also set course for these changes. Achieving sustainable development also at the stage of using food already produced should be based on optimization of all related processes, and thus also financial (mainly tax) processes. Therefore, attention should be paid in particular to the tax legislation in force in Poland and in selected European Union countries, i.e. the Act on tax on goods and services and the Act on corporate income tax.

Opis:
Marnotrawstwo żywności to problem, który nabiera szczególnego znaczenia w XXI wieku. Jak wynika z danych Banków Żywności co roku na świecie marnuje się 1,3 mld ton jedzenia. Stanowi to 1/3 wyprodukowanej żywności. W Europie jest to niemal 100 mln ton, a w samej Polsce prawie 9 mln ton rocznie [Banki Żywności 2016]. Dane dotyczące Europy nie obejmują strat w rolnictwie oraz rybołówstwie, czyli w rzeczywistości wartość ta może być znacznie większa. Z drugiej strony w krajach Afryki Subsaharyjskiej i Azji skala marnotrawstwa jest zdecydowanie niższa, a pomimo to występuje tu chroniczny problem niedożywienia, czy wręcz głodu. Jak donosi UNICEF niedożywienie jest przyczyną śmierci ponad 5 milionów dzieci rocznie [UNICEF 2016]. Dlatego konieczne jest opracowanie strategii skutecznej walki z tym zjawiskiem. Takie próby podejmuje Unia Europejska, która zwróciła uwagę na problem w strategii „Europa 2020”, a w roku 2011 Parlament Europejski wydał rezolucję „Jak uniknąć marnotrawienia żywości: strategia na rzecz poprawy wydajności łańcucha żywnościowego w UE” [Parlament Europejski 2011]. Jednocześnie duża część mieszkańców UE (w tym Polaków) deklaruje, że nie są świadomi sytuacji, nie zauważają kampanii informacyjnych i programów, które mają na celu zmniejszenie marnotrawstwa żywności [Federacja Polskich Banków Żywności 2013, s. 10]. Walkę z problemem XXI wieku należy zatem rozpocząć od podstaw, od budowania świadomości poszczególnych gospodarstw domowych oraz przedsiębiorstw wytwarzających i prowadzących obrót żywnością. Celem niniejszego artykułu jest wskazanie na problem marnotrawstwa żywności, jego przyczyny i przejawy, a także określenie możliwych strategii przeciwdziałania temu zjawisku. Metody badawcze zastosowane w pracy to krytyczna analiza literatury przedmiotu i metaanaliza z elementami wnioskowania dedukcyjnego, przy wykorzystaniu dostępnej literatury przedmiotu i raportów.
The problem of food waste is particularly relevant in the twenty-first century. According to the data from the Food Banks, 1.3 billion tonnes of food is wasted every year around the world. This represents a third of the total food production. In Europe, there are almost 100 million tonnes and in Poland there are some 9 million tonnes per annum (Food Banks 2016). The data on Europe do not include losses in agriculture and fisheries, which, in fact, make this figure much higher. However, the scale of waste in sub-Saharan Africa and Asia is much lower and there is a chronic problem of malnutrition and even starvation. As reported by UNICEF, malnutrition is the cause of death of over 5 million children annually (UNICEF 2016). It is therefore necessary to develop strategies to effectively combat this phenomenon. Such attempts are taken by the European Union, which pays attention to the problem in the strategy ‘Europe 2020’. In 2011, the European Parliament adopted a resolution ‘How to avoid food waste: a strategy for improving the efficiency of the food chain in the EU’. At the same time a large part of the EU population (including Poles) declare that they are not aware of the situation, do not notice information campaigns and programmes that aim to reduce food waste. Struggle with this twenty-first century problem should therefore start from building attitudes and awareness of individual households and firms engaged in food production and distribution. The purpose of this article is to point to the problem of food waste, its causes and manifestations, and to identify possible strategies to combat this phenomenon. Research methods used in this work include a critical literature analysis and meta-analysis with elements of deductive reasoning based on available literature and reports.

Opis:
Research background: The commitment to increasing the volume of agricultural production remains the main strategy for food supply in Ukraine. In fact, such an approach does not solve the problem of the limitation of food's physical availability. It works quite the opposite way, as there is a guaranteed food loss and waste, worsened environmental situation and decreased level of economic availability of food. Purpose of the article: According to the results of the empirical study, the volume of food shortages has been determined as a result of food loss and waste, food surpluses in case of compliance with the rational consumption norms and zero food loss and waste, as well as potential social benefits from reducing food loss and waste. Methods: The research of the limitation of the physical availability of the different types of products as a result of food loss and waste was carried out according to the methodology developed by the authors. In particular, for the group of products in which the consumption deficit is established in a small number of regions - the main indicator is the "production surplus in the conditions when the rational consumption norms and zero food loss are met"; for the group of products in which the consumption deficit is established in the vast majority of regions - the main calculation indicators are the "production shortage in the conditions when the rational consumption norms and zero food loss are met" and the "specific gravity of the consumption shortage, which occurs as a result of food loss and waste". Findings & Value added: The obtained results are crucially important for shaping of the food security policy. Reducing of the food loss and waste has positive social consequences through the expansion of the physical availability of food, which, under other conditions, leads to greater economic availability of products, as well as contributes to the gender equality and poverty reduction for rural residents.

Opis:
Anaerobic co-digestion of domestic sewage sludge with food waste as a substrate for biogas production and as a mean for waste management was conducted. The food waste was incorporated into the bioreactor as a cosubstrate semi-continuously via replacement mode and addition mode of operations in ratios up to 50%. The methane gas yield under the replacement mode of operation ranged from 295 to 1358 ml/gVSadded and from 192 to 462 ml/gVSadded for the replacement mode of operation and the addition mode of operation, respectively. The results indicate that the methane gas yield increases along with the percentage share of food waste in the feed. Anaerobic co-digestion under semi-continuous operation enabled handling large organic loadings compared to batch co-digestion processes.

Opis:
Zagadnienie strat i marnotrawstwa żywności jest głównym problemem współczesnej gospodarki światowej. Na szczególną uwagę zasługuje powiązanie go z bezpieczeństwem żywnościowym. To ostatnie, leżące w kręgu zainteresowania globalnych i regionalnych organizacji międzynarodowych (i nie tylko), próbuje się zachować m.in. przez realizację różnorodnych działań ukierunkowanych na ograniczanie zjawiska strat i marnotrawstwa pożywienia. Istotne w tym kontekście są działania struktur unijnych, które wniosły znaczny wkład w utożsamianie się społeczeństwa z przytoczonymi wyzwaniami i w głębszą jego edukację w zakresie racjonalnego gospodarowania zasobami żywnościowymi. Celem opracowania jest przedstawienie istoty problemu strat i marnotrawstwa żywności oraz ukazanie jego wpływu na zachowanie bezpieczeństwa żywnościowego. Do przygotowania publikacji wykorzystano metodę opisową, analizę krytyczną literatury oraz wnioskowanie oparte na indukcji i dedukcji.
The issue of food loss and waste is a leading problem in the modern world economy. Particularly noteworthy is its connection with food security. The latter, being in the field of interest of global and regional international organisations (and not only them), is tried to keep, among others, with the implementation of various activities aimed at limiting the phenomenon of food loss and waste. In this contect, noteworthy are the activities of the EU structures, which have made a significant contribution to the identification of society with the mentioned challenges and to its deeper education in the rational management of food resources. The aim of the study is to present the essence of the problem of food loss and waste and to show its impact on the maintaining food security. The descriptive method, the critical analysis of literature and inference based on induction and deduction were used to prepare the publication.
