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:
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:
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.

Hermetia illucens
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).

Opis:
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.
